Chapter 1: The Giant of Light Appears / Raise Your Hand and Call My Name!

Flash Sentry, a high school teenage boy who plays a guitar in a band is seen floating through a dark void with his eyes closed. He hears echoes out of a melody into the void before he slowly opens his eyes to see a ball of light hang towards him. The light was too bright, but he could see that there was some sort of figure flying right towards him. Soon the light engulfed him as he heard some sort of sound coming from it.

"Dah!" Flash quickly moved out of the way as he saw a giant figure within the light as it flew by before landing on some sort of giant asteroid in front of some sort of temple. He saw two other giants, one had a female figure while the other was a male, as all three of them were fighting some sort of enormous monster. The monster itself had very dark scales all over its body while it had a long neck attached to a head with glowing red eyes and a very sharp nose. The monster itself has very sharp metal claws and dark red armor along its back.

Flash noticed that each giant was covered in a bright light as they were fighting this monster. One quickly stopped to notice him as Flash saw some sort of gems coming from the temple before he was blinded by a bright light.

Flash then suddenly wakes up in his bedroom as he was awoken by his alarm clock when it went off. "What a strange dream…" He muttered to himself before he turned off his alarm. He then got out of bed and stretched his arms before walking over to the window and looking out into the city with a wonder in his eyes. "What were those things, those giants in those lights, that giant monster they were fighting and that temple that was filled with gems… it all felt so real." Flash then shook off those thoughts as he knew he didn't have time for that as he needed to get ready for school.

After a nice shower, brushing his teeth, he got dressed and went downstairs where his mother had already made breakfast and his little sister, Scootaloo, was at the table eating her pancakes. "Morning, Flash." Scootaloo grated as Flash sat down.

"Good morning, Flash." His mother greeted. "So, just a few days until the Fall Formal. Have you gotten anyone for the dance yet?"

"Mom, it's just a few days away and I have a band to practice with, so I have a lot to deal with." Flash mentioned. "Plus I also have a few assignments to do and I promised a few friends of mine to help them out with some problems they have."

"You know, that's why people like you so much." His mother mentioned as she placed down his breakfast in front of him. "You have such a good heart, always helping your friends out, having to find time to be yourself, and you never let that light inside of you die down. If your father wasn't in Japan for that business meeting, he would tell you the same thing." Flash smiled at his mother's remark as he knew she was right. "Now, eat your breakfast and get ready for school you two." As Flash began to eat his breakfast, he still couldn't stop thinking about the dreamy had last night and the three giants that were covered in light. To him, it felt all so real that he couldn't shake this feeling that things are going to change for better or for worse.

Up in space, a few light years away from the Earth, the battle Flash had dreamed about was all too real. The first giant flash had seen before had a silver full helmet with two fins on top and crust down the center of the back of it while he had oval eyes that glowed along with some sort of blue gem piece on his chest. He had armored shoulder pads with blue gems on them while his body being sort of a blue and red pattern of a diamond going down his arms, legs, and center chest. He launched himself right at the monster before the monster swung his claws and knocked him back to the ground.

"Delta!" A female voice called out before a female giant with curved horns on her silver helmet jumped in front of the first giant. The eyes of her full head helmet were circular while her body was purple with a star shape pattern and a six-pointed star gem on her chest. The monster then unleashed a laser from its mouth before the female giant held up her hands to create a shield that was in a diamond pattern to block the attack. "Are you okay?!"

"I'm fine, and thanks, Alpha." Delta said as he stood up before another giant came in and did a double kick towards the monster's chest. This one had a helmet with an M shaped on top of it while the eyes were in the shape of diamonds and his body was black and red. The gem on his chest appeared to be in the shape of a triangle as he flipped back to the other two giants. "Mega."

"Delta, Alpha, both of you stand your ground!" Mega ordered as he took a fighting stance. "I don't know how this monster found the Ultra Temple, but we know why it's here."

"The Ulta-Gems, containing the power of every Ultraman that has ever existed." Alpha said with a worried tone as she looked back at the temple they stood in front of. Inside contain many gems that had images of passed Ultramen throughout the ages. "If it gets its claws on even one of them, the universe is doomed."

"Stand your ground and unleash a unified attack on my command!" Mega ordered as all three of them stood ready. The ends of their hands began to glow as Ultraman Mega pumped both his fists before crossing them while Ultrawoman Alpha crossed her arms and Ultraman Delta circled his arms as they seemed to be charging up with power. "MEGA…"

"ALPHA…"

"DELTA…"

"FLASH!!!" All three of them declared as they crossed their arms into a t and fired powerful laser beams right at the beast. Each beam hit the beast as they had hoped to destroy it, but Delta noticed the horns on its head started to glow red and realized that they were powering the monster up.

"Alpha, Mega, stop! We're charging--" He tried to warn the other two, but it was too late as the ferocious beast opened its mouth and unleashed a powerful red laser right at them. They quickly dove out of the way but the laser struck the temple as it exploded into millions of pieces. The Ultra-Gems however remained intact as they flew right out of the remains of the temple. Delta saw this and quickly jumped to grab something out of the storm of gems that flew past them.

"The Ulta-Gems!" Mega called out when they saw the gems flying off into space.

"I've only managed to grab three of them!" Delta told the other two as he showed off two of the Ulta-Gems: Ultraman, Ultraman Trigger, and Ultraman Blazar. They then heard the beast let out a roar as Wings spread from its back. "It looks like it's going after the rest!"

"And they're all heading towards earth!" Alpha pointed out as the beast turned towards the direction of earth. Just before it could take off, Ultraman Mega quickly grabbed it by the tail as he was keeping it from flying after the gems. "Delta, go after the Ultra-Gems! Me and Alpha will keep it busy!"

"But…But I can't leave you both…" Delta said before he felt Alpha place a hand on his shoulder.

"Delta, who or whatever sent this monster is after them." She told him with a serious tone. "We can't let them fall into the wrong hands! We believe in you, little brother. And if you must, bond with a human whose heart is filled with light and defend that world!" She then charged right at the base before jumping onto its back as she was helping Ultraman Mega, to keep it from taking off.

"Alpha…Mega…" Delta muttered before he looked at the three gems in his hand and clenched his fist. "DAH!" He shouted when he jumped and started to fly off towards Earth, where all the other Ulta-Gems were scattered to. As he was a few miles away, an explosion was suddenly hurt before he looked back and saw there was nothing left of the place where he and his siblings fought the monster, nor his siblings. "No…" He whispered before he shook his head and continued his way to Earth.

Back on Earth, Canterlot High was just let out of school as Flash was walking beside Sandalwood and Micro. "Can't believe the Fall Formal is going to be a week away." Sandalwood mentioned. "Let's just hope there won't be any dangerous magic involved this time."

"With the Rainbooms around, it's a 100% chance of them making sure no magic ruins it this time." Micro calculated. "Hey, want to head to Sugarcube Corner for some nice milkshakes?"

"Yeah that sounds pretty nice." Flash replied before a thought crossed his mind. "Hey guys…" He spoke to get the two's attention. "I had this weird dream last night and it felt so real too."

"Really, what was it about?" Sandalwood asked as they were walking through the streets.

"Well, I was floating through space and I heard some sort of melody." Flash began to tell them about his dream. "I then felt like three giants covered in a bright light, but I couldn't tell what they look like and there was this giant monster with metal claws they were fighting against in front of a temple. I could barely see them, but I saw some gems inside of that temple they were guarding against the monster."

"Interesting." Micro said as he adjusted his glasses. "What happened after that?"

"Well, I just woke up and didn't see what happened after that." Flash replied before he bumped into a familiar violet skin girl. "Sorry about that, Twilight."

"It's okay, Flash." Twilight replied as she got up from the ground. "I was just doing some little experiment. Earlier, my readings detected some sort of strange energy signal coming not too far from space."

"Really?"

"Yeah, I'm hoping Sunset could help me out because the energy readings are like off the scales." Twilight mentioned before she walked away from them.

"You know dude, you should really ask her to go to the Fall Formal." Sandalwood told Flash.

"What?!" Flash questioned with a surprised tone. "I can't do that. She has a boyfriend, Timber from Camp Everfree."

"Yes, but he doesn't go to our school." Micro pointed out. "And there's no reason you can't go with her as just a friend."

"I guess…" Flash said as he had an unsure look on his face. 'But she's just similar to Princess Twilight from Equestria… Not that me and her had anything going considering I'm a human and she's a pony. It wouldn't work out between us anyway." As the three of them walked through the streets, his mind was still thinking back about the three giants fighting a giant monster in space and couldn't shake the feeling why he couldn't stop thinking about them. Meanwhile, someone in the shadows had a gauntlet on with a diamond shape screen on it. This person placed three red gems in the gauntlet before pressing down on the slider on the right side as it scanned each gem before pressing the trigger on the left side of the gauntlet.

Kaiju rise!
Gomora, Eleking, Basser!
Zet Gomora!

A bright red light shined from the gauntlet before a ball of light went up to the sky and opened some sort of large portal before it released red lightning before something came out of it. Everyone in the city soon felt the ground shaking like crazy before they saw something rising up. They saw some sort of giant, very buff dinosaur-like creature with blue scales mixed with white, black, and golden yellow down the center of its body. The creature itself had horns on its head that looked curvy while its eyes glowed red before it let out an earth rumbling roar as it spread its wings.

Everyone began to panic as it started to destroy buildings around it while it moved through the city. "What in the world is that?!" Sandalwood exclaimed when they saw the giant monster.

"I don't know, but it definitely doesn't look friendly!" Micro said as the trio started to run away, along with a large number of people from the monster.

In Japan, red lights were blurring as the sound of an alarm was blurring while a bunch of people on machines were at work. Soon a man with dark orange skin, light blue hair, and wearing a red and orange jumpsuit walked into the room with a serious expression on his face. "What's the situation here, people?!" The man questioned as a woman with light pink skin, ruby red hair, and wearing the same suit as the man walked up to him.

"Satellites have detected a massive energy surge somewhere above your hometown, Commander Trail Blaze!" The woman informed as she saluted him.

"Where is it and where is it coming from?" Trail questioned.

"It was detected over in the United States, sir." One of the workers answered as it was shown on a big screen. Trail looked at it as he recognized the location of where the energy signature was detected. "We believe a kaiju has appeared."

"That's Canterlot City, my hometown!" He exclaimed with a worried tone. "My family lives there!"

"There's more sir, this Kaiju has three unique energy signatures that are similar to three other kaijus." Another worker told him. "We've never seen anything like this before, sir."

"How long till the Fighter Wings are ready?" Trail questioned the workers.

"We already sent them the moment we realized it was a kaiju." One of the workers answered. "They're ETA is 5 minutes."

"And how long till Project Skybound is ready."

"3 hours." The woman answered as Trail let out a sigh. He then looked at the big screen with a worried expression as he gripped tightly on the rails in front of him.

"Be safe, Misty… Scootaloo… Flash…" He whispered under his breath.

Back in Canterlot City, the Kaiju continues its rampage as it destroys buildings in its way while people are fleeing for their lives. Three people however got trapped underneath the rubble of the building as they struggled to get free. Suddenly, the rubble that weighed them down was lifted off of them as Applejack was using her strength to lift it up. "Go on y'all, get!" She shouted as the people she rescued quickly got up and ran away, just as Rainbow Dash managed to get some people out of a building.

"That's everyone out of that building!" She called out, but didn't notice a big chunk of rubble about to fall on her if Rarity had not put up a diamond shield to protect her.

"At least be more careful around here, darling!" She told Rainbow as the rest of the girls were getting people to safety. "It's almost like a war zone here at this point!"

"What exactly is that thing?!" Twilight asked as she pointed towards the rampaging Kaiju.

"Um… I may know what it is…" Fluttershy muttered before Rainbow quickly grabbed her friends and moved them to a safer distance away from the giant beast.

"You know about that big, giant, dinosaur thing?!" Rainbow questioned Fluttershy.

"Well, remember when me and my family went to Japan when we were in grade school for a summer?" Fluttershy asked her friends as all but two of them gave a nod in response. "Well, I enjoyed our vacation so far before a giant rampaging lizard-like monster attacked Tokyo. The locals called it a Kaiju…"

"Wait, a minute, is that what that thing is?" Sunset asked before they saw the Kaiju sparking up its horns before it released a red laser beam that shot across the city. An explosion was left in its path as it startled the group. "Let's talk more about that after we get everyone to safety!" As the Rainbooms continued to get people to safety, the Kaiju was about to unleash another beam before something fired right at it, causing it to stumble back.

Soon four large colorful jets came flying by as each of them looked very advanced with a number on each of them. "This is Surge Light, we've reached delta point and are now engaging the Kaiju!" A man with light blue skin, orange hair under a helmet, and wearing an orange and red and orange jumpsuit piloting the blue jet with the number one. "Sapphire, you're with me on keeping that thing at bay!"

"Roger that!" A woman with dark yellow skin and dark pink hair under a helmet called out from the green jet with the number two on it.

"Chemical, keep your distance and I want you to get a reading on that Kaiju!" Surge called out to a man with dark green skin, red hair under a helmet with glasses piloting the orange jet with the number three on it. "I want to know where we're dealing with here!"

"On it!" Chemical called out as he started circling the Kaiju while pressing a few buttons on his console. "Now let's see what you're made of…"

"And Star Shine, help evacuate any civilians that are having trouble getting out!" Surge commanded a woman with aquamarine skin, pink and purple hair under a helmet as she was piloting the fourth jet that is colored yellow.

"Way ahead of you!" Star replied as she pressed a few buttons before grabbing a mic and speaking into it. "All civilians, follow my Fighter Wing to safety! We have everything under control!"

"Who are these guys?!" Rainbow asked her friends as they saw the Fighter Wings flying by.

"I don't know, but they look like they're helping us out." Sunset mentioned before she looked at her friends. "Come on, we need to help everyone else out!"

"Okie dokie loki!" Pinkie said it with a salute before she saw Mr and Mrs. Cake running up to them with worried expressions. "Hey, what's the matter?"

"We were out delivering a cake before that monster arrived!" Mrs. Cake started with a very worried tone.

"We then realized we left Pound and Pumpkin Cake back at home!" Mr. Cake added with the same worried tone. "We have to go get them!"

"Whoa, whoa, whoa!" Rainbow quickly stood in their way. "It's way too dangerous to go back in the city! I'll go get your kids."

"She's right, it's way too dangerous for anyone to go back there." Twilight told the couple. "Come on, we have to get you both to safety and Rainbow will get your kids." She and Sunset escorted the couple away just as Rainbow Dash used her super speed to run back to the city.

Meanwhile, Flash was running through the streets of the city as he had a worried expression on his face. "I really hope mom and Scootaloo got out okay." He said to himself before he heard a couple of babies crying when he passed Sugarcube Corner. He quickly stopped and went inside to find the Cake Twins crying. "Oh man, your parents must have gone out on a delivery before this happened." He theorized before he looked back at the Kaiju that's still on a rampage and then back at the twins. "I'll get you both to your parents, don't worry!" He quickly went in and grabbed the twins before running out.

Meanwhile, both Surge and Sapphire continued to fire at the Kaiju in their Fighter Wings before they took evasive maneuvers when it shot red lightning from its horns. "Damn, this thing is really tough!" Sapphire called out.

"And I think I may know why." Chemical called in through their communication network. "I did a full analysis on this thing and when I found out about this thing it was really shocking."

"What did you find out?" Surge asked as he dodged another lightning strike from the Kaiju.

"This thing is three kaijus in one!" Chemical answered, which surprised and shocked his teammates. "It has Gomora, Eleking, and Basser energy signatures in one!"

"How is that even possible?!" Star Shine asked as she was using her Fighter Wing to get people out of the city.

"I don't know how… Wait, something is entering our atmosphere." Chemical informed the others with a confused tone. "Multiple things…" Before any of them could ask him what he meant, they suddenly saw a bunch of small gems shining as they fell from the sky.

Outside the city, the rest of the girls and Star Shine got the people to safety before they saw the gems falling from the sky. "What is all this?" Applejack asked as the gems continued to fall from the sky.

"I don't know, but it sure is sparkly." Pinkie commented just as Twilight noticed one of the gems landing not too far from where they are. Twilight went over, kneeled down and cautiously picked up the Ultra-Gem. It shined in her hand for a bit before the light died down to reveal an image of Ultraman Geed.

Back at the city, Flash saw the gems falling from the city as he continued to carry the twin babies in his arms while trying to find their parents. He was distracted by the gems falling and focusing on finding the Cakes, he didn't see the Kaiju walking towards him and was about to get stepped on. He noticed the shadow looming over him as the Kaiju was about to step on him and the twins, but suddenly a bright flash of light appeared in the sky as a familiar figure was seen flying down.

"Dah!" Flash heard a familiar sound as something in the light kicked the Kaiju back before landing on the ground. Flash looked up and saw the light die down as it was revealed to be the Giant of Light himself: Ultraman Delta. Flash, the four pilots, and everyone outside the city gazed in awe at the giant of light as Delta took a battle stance, ready to fight the Kaiju but Flash recognized Delta as he remembers seeing something similar in his own dream.

The Kaiju let out a roar before Ultraman Delta charged right at it as he threw a punch right towards its chest. He then blocked an attack from one of its claws before he jumped and kicked it back. "Guys, is it really him?" Sapphire questions her teammates.

"It is… the Giant of Light…" Chemical said in awe as Ultraman Delta flipped back to dodge an attack from the Kaiju.

"Ultraman…" Surge finished when Ultraman Delta delivered a punch to the Kaiju's face.

"That's…" Flash started as he couldn't believe one of the giants from his dream was real.

"Flash!" He snapped out of it when he heard Rainbow going out to him before he turned to see her running up to him. "Oh good, you found the Cake Twins."

"Uh yeah, I was just on my way to find their parents and stuff." Flash said as he handed Rainbow the twins before he pointed towards Ultraman Delta and the Kaiju. "But you are seeing this, right?"

"Yeah, it's pretty insane and we can admire it from a very safe distance! Rainbow mentioned before the Kaiju grabbed Ultraman Delta by the throat before throwing him back. He then crashed onto a building near Flash and Rainbow. Flash quickly pushed Rainbow out of the way as a bunch of rubble fell right on top of him. "Flash!" She called out before the smoke cleared as she saw him with a large chunk of rubble on top of them. "Are you okay?!"

"I'm…I'm fine…" Flash groaned before he looked at Rainbow. "Just…get those kids back to their parents, now. They're probably still worried sick about them."

"Okay, but I'll be back with Applejack to get you out!" She told him before she used her super speed to race back to Mr and Mrs. Cake. When she was gone, Flash struggled to get the rebel off of him before he felt something under his hand. He looked and saw the three Ultra-Gems shining on the ground before he picked them up. He then saw the images of Ultraman, Ultraman Trigger, and Ultraman Blazar on each of them.

Meanwhile, Ultraman Delta set up as he held his head. "This one is much stronger than the last…" he said to himself before he realized something as he looked at his hands before looking around. He then noticed Flash holding the three Ultra-Gems he had dropped but they were still shining. "They're reacting to him… Could he…?" He wondered as he remembered what Ultrawoman Alpha told him before. He then heard the Kaiju roar before he noticed energy building up in its mouth. "Oh no!" The Kaiju then released an energy beam straight towards Flash just as Ultraman Delta jumped right towards him as his body glowed bright.

Flash slowly opened his eyes and found himself in a place filled with light around him. "Wha…Where am I?" He asked himself as he looked around.

"It's okay, you're safe now." He heard a voice before a light shined in front of him before Ultraman Delta formed in front of him. "I brought you here."

"It's…It's you…" Flash gasped when he saw the giant of light in front of him. "You're one of the giants I dreamed about. I saw you in three other giants in space fighting some sort of monster in front of a temple."

"You how to dream about me along with my brother and sister?" Delta asked as he thought for a moment before he shrunk down to come face to face with Flash. "Well, if you had seen me before, I might as well introduce myself. I am Ultraman Delta. The other two you saw in your dream was my older brother and sister, Ultraman Mega and Ultrawoman Alpha. All three of us were tasked into protecting the temple that housed the Ultra-Gems."

"Ultra-Gems?" Flash repeated before the gems that he picked up suddenly shined in his hands, causing him to look at them.

"Gems that were created in honor of past Ultramen, they hold memories and powers of the Ultramen and they are extremely powerful." Delta explained. We've guarded the temple for thousands of years as it was well hidden, up until now. Somehow a Kaiju has found the temple and we did our best to defend the temple from it, but…" Flash noticed he clenched his fist in anger as Delta remembered his brother and sister's sacrifice. "The Kaiju destroyed the temple and the Ultra-Gems were scattered onto your world. My brother and sister held off the Kaiju so that I may able to come to Earth and find the gems. Although, I did not expect another Kaiju to be here when I arrived."

"Kaiju?" Flash said before he realized something. "Is that the thing that's attacking the city?!"

"Yes, and you almost perished when it fired its beam right at you." Delta mentioned. "You would have perished, if I have not saved your life and brought you to this Ultra dimension."

"Is that where we are?" Flash asked before he wondered something. "But why did you bring me here?"

"Because you have a heart of light." Delta answered. "The gems reacted to your touch and my sister, Alpha, told me that if I must, I have to bond with a human whose heart is filled with light. The Kaiju is too strong for me to face alone, but with the power of the Ultra-Gems and you, will be able to defeat it and save your world. But, it can only be done if you accept this offer."

Flash thought for a moment as everything Ultraman Delta told him was a lot to take in. Then he thought about his dream and wondered if it was really a vision and it was fate that the two of them had met. He then thought about his hometown, his friends and family in danger because of this Kaiju. He then clenched his fist before he looked at Ultraman Delta with a determined look. "If the darkness is going to hurt those I care for, then we will defeat it with our light." He told Ultraman Delta as he held out his hand, accepting his offer. Ultraman Delta nodded before his body shined bright before he became a ball of light that flew over onto Flash's left arm. Soon the light died down and a gauntlet was formed on his arm.

It was a black and blue gauntlet, being black leather covering his lower arm whilst the blue metal covered the back of his arm and his entire hand. On the back of the gauntlet, embedded in the metal, were three slots of some kind.

The gauntlet also had a button of some kind on the back of his hand, along with a black leaver that was connected to the left and right side of the gauntlet whilst the grip was above it. The side of that grip had a red button on it, where Flash's thumb would go whilst holding it. And from what Flash could tell, the leaver could move backwards and forwards over the section that had the slots on it.

"This is the Ultra-Gem Rise Gauntlet." He heard Delta's voice explain. "Insert the gems into it and you'll be able to transform with me. But a fair warning, will only have three minutes before you transform back and then you'll have to wait 20 hours before you can transform again."

Flash then realized something when Delta mentioned the time limit. "Oh man, the Kaiju must have destroyed the city by now!" He said with a worried tone.

"Don't worry, here in this Ultra dimension, time moves differently here." Delta told him. "Minutes here would be seconds out there. If you want to save your world, let us transform together and protect the light!" Flash had a determined look on his face as he clenched his fist before he looked at the gauntlet.

"Let's do this!" Flash declared before he pressed the button on the back of his hand, making the whole thing light up with light blue. He then took the three Ultra gems and placed them in the slots.

He then grabbed the leaver in his hand and pressed the button on the side, causing the bottom of the leaver to unleash a line of blue light. And as he pushed the leaver forwards, the light washed over the gems. And as it did, the gauntlet spoke before an Ultraman appeared out of the gems.

Ultraman

Ultraman Trigger

Ultraman Blazar

Ultra Rise!

Soon Ultraman Delta appeared behind Flash as he stood tall in his giant form. "Okay, now what do we do?" He asked him.

"Now raise your hand and call my name!" Delta declared as Flash clenched his fist and thought about saving his home, his family, and all of his friends. Determination filled his entire body as he opened his eyes with a spark in them.

"Ultraman Delta!!" Flash called out as he raised up his hand with the gauntlet on it and waited for something to happen.

"Pisst, pressed the trigger on the left side." Delta whispered as flash noticed the trigger on the side of the gauntlet.

"Oh, right." Flash quickly pressed the trigger before he did a pose and he transformed into Delta as a gem formed around him. The other three Ultraman soon collided and a burst of light soon beamed up into the real world.

Ultraman Delta: Strike Type!

Soon a portal of light opened up as Ultraman Delta emerged from it upwards while he raised his fist up high and grew to his giant size as his appearance seemed different. He had Ultraman's colors on his body with Ultraman Blazar's was honest chest with Ultraman Trigger's golden cuffs on his wrists and ankles with blue gems in the center of them. Finally the helmets of each Ultraman were fused into one as he raised his arm up high. "Dah!" Ultraman Delta shouted as he stood tall before taking a battle stance at the Kaiju.

Earlier, Rainbow had returned the Cake Twins to their parents and told her friends about Flash being in trouble before they saw a beam of light emerging from the city. They then saw Ultraman delta, in a different form standing tall as they were surprised by his new form. "W-Wait, that's where Flash was!" Rainbow said with realization.

"Come on, we got to make sure he's okay!" Sunset said before Applejack stopped her from going forward.

"And get caught in the crossfire?" She asked rhetorically. "I think we should wait until it's safe to go in."

Ultraman Delta stood his ground as Flash could feel the immense power coursing through him. "So this is what it's like to be an Ultraman?" He asked as he looked at himself. "This is incredible!"

"Yeah, now let's put this power to use!" Delta declared in Flash head as Flash nodded and took a defensive pose as the Kaiju roared and charged right at him. Delta quickly dogged the upcoming claws as he evaded by quicky side and delivering a side punch right and Zet Gomora face making the Kaiju take back at the pain. Delta took the opportunity and charged back at it as he jumped in the air and spun around as he came flying down at the Kaiju and kicked it right in its stomach as it fell back on the ground as Delta landed back on the ground. Zet Gomora got up as his crimson eyes glowed in anger and used his electricity to attack again but Delta dogged quickly and cartwheeled in front of Zet Gomora and delivered a few punches right to its chest. But then the Kaiju swung its claws and got a few hits in as sparks came off of Delta before he was thrown back.

The Kaiju horns glowed red as well as its red veins on its body as it was getting ready to launch its energy ray at the Ultraman. Flash inside saw this and quickly got ready as outside Ultraman Delta arm braces glowed purple as Zet Gomora shot his beam at him as Delta quickly constructed a shield in front of him to block the strike."SHAAWWW!" He pushed the beam back as he used his strength and launched the shield at the Kaiju as it hit directly at the Kaiju face making it yell in pain. "HAAAAHHHHHH!" Delta then suddenly pointed his hands in front together as energy constructed in his hands as he opened them wide and created an energy spear.

This ability belonged to Ultraman Blazer as it was his signature weapon used against long range enemies and perfect for close weaponry. He let out a cry as he swung the energy staff and hit the Kaiju in the side in a quick manner as the Kaiju let out a cry of pain and anger. Delta spun around and quickly got another strike but that was when Zet Gomora had enough and used his wings to push Ultraman back trying to get him away.

"Shoot! It's holding us back by the wind and it looks like it wants to take off in the air to fight us!" Delta said in Flash head as Flash looked at the Kaiju flapping its wings upwards and started to lift off the ground. The winds were strong as it started to push the buildings and the things away. The people near the area who were running away from the fight were accidentally caught in the hurricane that the Kaiju was causing as somewhere trying to hold on to things to not being flown away and such as they held on for dear lives. Flash and Delta quickly heard the cry of help and looked back to see some people who were still trying to hide caught in the crossfire. "Shit! We have to do something quick before anyone else is hurt by the Kaiju!" Flash quickly told his partner.

Delta used the energy stick and launched it right at the Zet Gomora as it came through the wind and hit the Kaiju dead on the side chest making It yell out in pain. It flew upwards from there and towards the sky as Delta quickly followed by flying upwards.

Zet Gomora flew in the air as it thought it lost the Ultra. But soon it heard a yell as it looked back to see the Ultra chasing after him. He growled as he used his wings to launch a burst of wind at the Ultra but he momentarily dodged the beam and flew upwards and launched two energy blades at the Kaiju. The Kaiju launched red electricity at them as their attack collided as an explosion occurred in the air.

Meanwhile, at the top of a building area. The one from before who made the Kaiju appear stood on the top of the building as he observed the ongoing battle. He wore a long gray coat and a hat over his head to shadow his face and see the fight happening in the air.

"This is certainly good. An Ultra in this world and this one seems to have the thing I need." He chuckled a bit as he held up his hand that had the Gauntlet. "This would be a perfect opportunity to learn about what I'm gonna be dealing with in the future." He said while rubbing the gauntlet as it glowed red.

The battle continues on as Ultraman and the Kaiju keep up with one another. The fighter jet pilots were seeing this as they flew in close."Looks like Ultraman is having some trouble!" Sapphire called out before Surge flew by and started firing at the Kaiju.

"Then let's lend him a hand!" He called out as both him and Sapphire started firing at the Kaiju. With it distracted by the two flyers, Delta got up as his hands started to build up with power. He soon slashed his hands as buzz saws made of energy were shot out and hit the Kaiju. The Kaiju roared before it started flapping its wings that sent the Fighter Wings flying back as Ultraman Delta came at it and made an energy spear and launched at the Kaiju back that made it lose its balance as it had enough and decided to end this. It turned around as it's body glowed more and more as its mouth was beginning to glow red.

"This thing is going for the kill!" Flash shouted before the gem in his chest started beeping red. He felt himself getting weak all of a sudden. "I'm guessing that's our timer for our transformation!"

"It is and that means we need to end this now! So let's use our own attack" Delta told him as Flash suddenly had a thought to him as both him and Ultraman Delta were sharing the same mind. "Are you ready?"

"Let's go!" Flash called down before Ultraman Delta crossed his arms into an X as they once again were building up with power. Soon he started to Circle his arms as he was preparing a final strike against the Kaiju who had gotten himself ready and finally launched its own red beam at the Ultra.

"DELTA STRIKE FLASH!!" Ultraman Delta declared as he crossed his arms and Unleashed a powerful beam of energy straight at the Kaiju own beam. Both attacks collided with one another as they were pushing one another back. Delta wasn't gonna give up nor was Flash as he struggled a bit."I-Im Not gonna let you destroy my world! We will stop you!" He shouted inside Delta as he used his energy in him to push his attack further overpowering the Kaijus attack.

The Kaiju didn't have any time to escape as Delta's attack broke through the beam and hit the Kaiju dead in the chest as it was sent down on the ground. It's body couldn't handle the attack and soon-

BOOOMMMM

Ultraman Delta soon landed on the ground as he looked to see the Kaiju was taken care of. The Fighter jets flew by him as he looked at them from below as they could see him from above as they cheered for him. Delta just gave them a nod in understanding. With the job done in the end he knelt down and flew off into the sky. "SHAAAAAHHHHHHH!!" He yelled out his signature cry and flew away.

Soon the people of Canterlot cheered along as they were overjoyed that the Ultraman won. However, the Mane Seven was curious as to who Ultraman Delta was and wondered what happened to Flash, but Twilight was most curious as she looked at the Ultra-Gem she had in her hand and Ultraman Delta. "This is Surge to base, you're not going to believe who arrived here today. Surge reported in.

Ultraman Delta soon landed just outside the city before he felt exhausted and his body became light dust. Soon he transformed back to Flash Sentry as he laid on the ground. "Man…what a rush…" He panted before he looked at his wrist and noticed that the gauntlet had turned into a wristband with a blue diamond on it. "I guess… I pressed that…when I needed the gauntlet…"

"That's right, we did good today." Flash heard Delta's voice in his head. "But I have a feeling that it is just the first wave. More kaijus will arise and we must find all the ultra gems here on Earth if we have any chance to stop them."

"Okay…how many gems are there exactly?" Flash questioned.

"You don't want to know."

Meanwhile at the spot where Zet Gomora was destroyed, the three red Kaiju Gems laid on the ground before a shadow loomed over them. A dark gray hand then picked up each gem before the figure stood tall as he looked at them with a grin on his face. "And so the games begin." He said with a dark chuckle before he walked away.

Author's Note

Here is the little melody that Flash heard in his dreams:

And if there's any Ultraman fans out there, I like your opinion on what kind of combination should Ultraman Delta get throughout this series.
