As the portal opened up, our heroes jumped out and saw where they are. Most of the mobiun heroes were surprised by where they were at, the equestrian heroes were in awe at the place, while Sonic cringed at the place.

He didn't like this place much. It was the hydrocity zone! A ancient aquatic ruins in angel Island. A floating lsland that's usually hidden in the sky, is also home to the master emerald. The most powerful object In the entire universe.

Twilight, Spike Rainbow dash, And Amy rose were amazed at the beauty of the ruins. Spear and Tails had memories of their adventures here. While Sonic DID think that it looked interesting, there was one thing that bothered him. "Ugh, water. Why did it have to be water?"

Spear turned and smirked at Sonic saying "Oh come on Sonic, don't tell me your still afraid, are you?~" Sonic tensed up, knowing that Spear was on the money on that. "I-I'm not afraid! ...I just don't like getting wet..."

Twilight then looked at Sonic funny and said "Wait, you don't like water? Why is that?" Amy then decided to tell them, so they can be up to date of Sonic's fear. "Sonic doesn't like the water, because he can't swim. So he avoids the water if he can help it."

Sonic gulped and shook in fear a bit. The only time he actually faced he fear was when Amy was knocked into the water, out cold, and Sonic was desperate to save her. If there was ONE thing he was more afraid of then water, was Seeing his friends near death. Especially Amy.

Spear then snapped Sonic out of it and said "OK, since this IS a area that can be dangerous, and especially with water all around. I vote we stay together on this one, ok? That way we can-"

Spear then looked around and said "Wait, where are-" "Rainbow! Get away from that!" They all turned and saw Rainbow dash try and get into one of the waterslides that made up the hydrocity area. "Aww come on Twi, this looks so fun!"

Twilight looked at it with concern and said "But who know WHERE it leads. It could be danger-" that was the last thing she said before getting pulled with Rainbow dash on the slide and flew through the zone.

Sonic then said "We better go after them! They don't know their way around here!" Everyone nodded and began to run after them through the zone.

As the heroes ran after Rainbow dash and Twilight, they saw the saw the ruins in all their glory. However, they soon ran into a badnik horde made of Blastiods, Mega choppers, Jawz. Sonic,Spear and Tails took them out with ease, While Amy kept Spike Company As the others took out the low level badniks.

Despite the tech that Eggman left behind, the artifacts that were left untouched were beautiful. However, there was something in the area that seemed...out of place. Sonic,Tails and Amy looked at the black crystals with curiosity, wondering where or when they came from.

Sonic then said "What are they? I didn't see these the last time we were here." Amy them suggested "Maybe you missed them the last time you were here? You WERE chasing Eggman and knuckles to get the emeralds back from them." Spike was confused and said,"Dose this knuckles guy work for Eggman? Why are we rescuing him if he can Cas us trouble later on?"

Tails then explained "Well, at first he did. But Eggman tricked him into thinking that we were the enemy so he can get the chaos emeralds to power his ultimate weapon at the time, The death egg. But I'll admit, even I don't remember these crystals here the last time we were here."

Spear then looked at them closely. Something about them felt...familiar. like he saw them before. Spike then saw them glow and remembered what they were and said "Look out! There crystals made from King Sombra!"

Spear heard and understood what Spike meant and saw the Crystal charge up with magic. He then Said "Everyone, out of the way! Move it!" It was too late as everyone else was shot by Sombra's fear spell. Spear managed to dodge out of the way thanks to Spike's warning.

That's when Spear and Spike heard a new voice. "HAH, HA HA HA HA HA HA HAA!"It was deep and Menacing. But Spear recognized it immediately. 'No...how is HE back?! He should be-'

Then they saw what looked like a while cocoon like object that appeared in front of them. On the base of it, was a metel plate and opened to reveal an dark orange eye in the middle of the plate. The cocoon cracked open and a flood of black energy poured out and... was covering Spike's body?! A black bubble then engulfed him and for a few moments, everything was still.

In the bubble, Spike began to wake inside as he felt...warm. This feeling was scary, yet strangely familiar. He then heard the voice again as it said "Heheheheh. Well, Well, I never would have imagined a member of your clan was all the way out here."

Spike looked around confused, wondering who was saying that. "Of course, you look different from the members I saw in the past. Perhaps after centuries of living on this planet, your clan adopted to the magic of this world? Intrigued. "

Spike then saw what was in front of him. A squid-like alien wearing royal garb and had three orange eyes on his face. The alien looked at Spike with a intriguing look and asked "Tell me young one. How much do you know about your origin?" Spike then Shook his head, not knowing anything about his past. "I see...so your heritage is unknown to you. Well, perhaps we can help each other out then?"

Spike then spoke in a shaken voice and said "W-Who are you? A-And what do you want with me?"

The alien chuckled and said "There is no need to fear young one. I have no interest in hurting you. I am called Black Doom. Leader of the black arms. And your species and mine, are closely related."

Spike then said "M-My species? But I thought I was a dragon?" Black doom then explains about Spike's heritage. "You are half correct. You are a dragon, but also have DNA of a species called...the scaled arms!"

Spike was surprised. All this time, he was only part dragon. He didn't think he was part alien. He them asked "How is this possible? How I'm I a descendent of the scaled arms?"

Black Doom then said "If you want to know how your heritage was like, then I am willing to tell you. However, there is something I need from you in exchange."

Spike then gulped, nervousness asking "And what do you want in return?" Black Doom then said "Find the one who is using our resources for their our gain, and terminate their goals. Only then, will your ancestors be at peace." Spike then wondered if he should be trusted. Was he being legit about what he was saying? He didn't know anything about his family, and he says that he knew his heritage.

Spike decided to be cautious and said "Ok, you have a deal. But, how can I deal with whoever caused this mess? I'm not exactly powerful on my own yet."

Black Doom then chuckled and said "Have no fear young one. Since the scaled arms and the black arms are similar in biology. I can grant you access to the elemental powers of the Black arms."

Spike then saw the black energy from the bubble then get absorbed in his body as Spike felt discomfort at first, absorbing all this power at once. But his body adjusted by growing a bit, he wasn't as big as Twilight, but he was definitely taller then the cmc now. He's probably around the same height as your average pony now. Just still shorter then the main six.

He then felt electrical energy from his claws and started to wave them around and he fired bolts of energy from his claws. They had the same green color his flames had, but had black electrical energy trailing behind them. They were called his Doom Spears.

Spike then noticed a new pair of wings on his back. They were small and dragon-like but allowed his still small body to fly. He then noticed as he flapped in place, energy build up in them, so he focused on them, stretched his arms out and he fired crossed Crescent waves of green energy forward. He decided to keep the doom theme and call them the Doom Aero slashers.

Before fading out, Black doom said "There are two more power seals lost in time. Find them to unlock more power and learn of your heritage. The legacy of the scaled arms. Use your new powers as you see fit."

As time resumed, Spear felt some of the black arms power get absorbed into him as well. As he had Shadow's dna in his genetic make up, it was naturally attracted to him. It just gave him a enhancement on all his powers, with one exception.

Spear's Hands then glowed a deep red color, he raises then to the air, and launched his arms out, and a volley of dark energy bolts with black energy following behide them fired down a bit away from the others, stuck to the ground, and exploded in the ground. Spear noticed that this attack was similar to Zamasu's blades of judgment, so he decided to call this move, Doom Blades.

Spear then turned to Spike and said "Are you ok Spike?" Spike looked at Spear and hugged him. While getting new powers was cool and all, it was still a freaky experience for him.

Spike them told him all that happened as he hugged him. Spear then said "Spike. Even if your actually a alien, we still love you all the same. Don't let your past decide your future. Make it your own."

Spike then nodded and said "Your right. Whatever I learn about my heritage won't change how I grown up or that you guys are my real family. Heck, if Sonic,Tails, and...Even Amy..."

Spike then had a lovey dovey look as he daydreamed about him and Amy in a romantic moment. As Spear then said "Hey Romeo~ stop fantasizing for a minute." Spike snapped out of it and blushed a bit and continued "Well, i consider those three as family as well. But it would cool to learn how my heritage was like. Maybe even get more of those powers too."

Spear then laughed and said "That's my little brother! Always aim to grow stronger and defend those you care for. Even if others say say otherwise. We won't become the darker side of us!

They began to hear music as the fear spell stopped and they recollected their bearings. They then heard the music as Spear and Spike took the stage on their song.

I bet you feel like you’re all alone. Like it eats away at all your days. Don’t fool yourself and never give in, no! With every time you held your own. Living life just scanning through the maze,Without a way - oh. Just nevermind what they were thinking!

Unjustified (justified), Won’t slow me down. Unbearable (bearable), Can’t hold me back! Unreachable (reachable) Don’t tell me what for ‘Cause I know I am the one in control!

I should’ve never stepped away! From all the hardships I have saved! Fell into all these cruel mistakes! Reliving all I’ve ever paved! In all the choices led astray! To all the outcomes of today! You know I won’t Become the darker side of me! (Darker side of me)

As both Spear and Spike got into the groove of their performance, they heard a badnik Hoard on there way, made of pointdexter,
turbo spike,bugernauts, and decided to test their new powers on them as Spike took on the second verse.

With every step you take it burns. Seeping deeper down into your soul. C’mon, wake up now and get back up on your path! With each time you hold your own. You’ll remember what’s inside of you! (Yeah) Don’t ever throw it all away!

Unjustified (justified) Won’t slow me down! Unbearable (bearable) Can’t hold me back! Unreachable (reachable) Don’t tell me what for ‘Cause I know I am the one in control! The one in control!

As Spear and Spike finished off the badnik, Sonic and the others were confused. What happened after that weird magic hit them? They all wanted to ask them now, but decided to let them finish there performance before asking.

I should’ve never stepped away! From all the hardships I have saved! Fell into all these cruel mistakes! Reliving all I’ve ever paved! In all the choices led astray! To all the outcomes of today! You know I won’t Become the darker side of me! (Darker side of me) With every step you take it burns !(Darker side of me) Darker side of me!

As the two of them finished, the heard a applause from beside them and saw the others clapping at their performance. The two of them blushed as Sonic said "Nice performance you two! Maybe we should start a band together one day."

Spike and Spear gave a fist bump as they all heard a *plop*. They looked at the right exit and said Twilight and Rainbow dash, soaked fur and all. Spear walked up to them and asked "What happened to you two?"

Twilight then gave them a annoyed look and said "Don't. Ask." She then gave Rainbow dash a dangerous glare as Rainbow dash gulped and began to fear Twilight for a moment. She knew a angry Twilight, was a dangerous Twilight.

She then turned and saw Spike and excitingly said "Spike! Your ok! I was worried when Rainbow dragged me away on that slide!"

Twilight then hugged Spike in a tight embrace, glad that weird magic she sensed earlier didn't effect Spike's mind or personality. But one thing she DID noticed was the new wings on his back. She was shocked, yet happily surprised and said "Spike...YOU HAVE WINGS NOW?!"

Rainbow dash then looked and beamed a grin so big it would make Pinkie pie jealous. She then said "You know what THIS means? A NEW FLYING BUDDY!" Rainbow dash then hugged Spike and nuzzled his cheek in excitement. Happy to have another flying buddy around.

Sonic then asked "What happened to us? And What was that weird beam that shot at us like that." Spear and Spike began to explain what happened. Sonic,Tails, and Amy were shocked at what they heard and said "WHAT?! BLACK DOOM?!" Amy then said "But-But how can that be?! I thought you and Shadow defeated him and destroyed the black comet two years ago!"

Spear then crossed his arms and said "Yeah, that's what I thought too. But, From the look of it, I say that he isn't after us or even mentioned us. But..." Spear gulped and said "It's possible he still has a grudge against Shadow more then any of us. Remember, he was supposed to be his strongest weapon in his conquest of earth. And I don't think he's gonna let it go so easily."

Twilight and Rainbow dash were filled in on who Black doom was, as well as Spike, who was surprised that they faced him before. Twilight then said " Is he a threat at the moment?" Spike then interrupted and said "No, he didn't seem like he was interested in any of us, except for me. He wanted me to find out who was using his resources and stop them. Since it crosses with our goal to stop this time monster thing, I figured we would need all the power we could get. So..."

Sonic and the others nodded and understood why he did it. Amy surprisingly was the one who said "It's ok Spike. If I was in your place, I would want to learn about my heritage too...After all, I never knew about my family's history either."

Sonic and the others heroes of mobius then remembered that She and Sonic are Orphans and don't remember their parents anymore. Spear was the only one who was adopted by a large family and they made his friends honorary members of the family. That's why he was so quick to adopt Scootaloo back at the orphanage. He didn't want her to feel abandoned like he was in his youth.

Twilight, seeing Amy comfort Spike, made her jealously grow more. She decided to talk about this to her when they got back to ponyville, but for now, they needed to find their friends first.

As they talked for a bit, Spike then spoted three white statues behind a wall. "Guys, look! There's three statues right there!" The others looked and saw who was there, and we're surprised. "Applejack!/Knuckles!/SCOOTALOO!!!"

Spear ran over to his petrified daughter and looked worried. "Scootaloo,sweetie? Are you ok?! Scootaloo!" Spear started to have tears in his eyes as he saw his precious daughter in such a state. He then looked back and said "Sonic, what are you waiting for?! Use the wrap ring and get us back th ponyville, NOW!"

Sonic was surprised at the sudden outburst, but did as he told. He used the wrap ring and it connected to sweet apple acres as Spear grabbed Scootaloo and jumped through the ring. Sonic grabbed knuckles, and Twilight grabbed Applejack. They all when into the ring as it vanished. With three more of their friends in hand, the search for their missing friends continues.
