Rogue flew to wards Umbra's army getting ahead of it and landed before the army and focused all of his elemental powers and his magic raising all of them as high as he could going right to the edge of loosing control. "This is it, I have to use everything I have, all my elemental powers and my magic." Rogue said as his power surged higher and higher as he tapped into his legendary potential that had gone largely unused up until this moment. "UMBRA, YOUR NOT GOING ANY FURTHER!" Rogue shouted as he stamped one foot on the ground making blades of rock and metal burst from the ground shredding anything on the ground as he waved an arm up and brought it down making multiple lightning bolts strike at once forcing the Anubis like race back as well as killing some of the smaller monsters like Timber Wolves.

Umbra looked down at Rogue from her place atop the crystal dragon and she stood. "What can you do against my army by yourself, little Rogue?" Umbra asked with a smug cocky tone, only for a burst of blue flame and a beam of light to strike the crystal dragon from the west and north.

"He's not alone." Atlas Flame said landing to Rogue's right.

"You can say that again." Starfall Redeemer said landing to his left.

"Sentinels." Umbra hissed. "I thought your cast would have died out by now." She said as her face twisted into a snarl showing off her sharp teeth.

"Happy to disappoint evil doer." Another male Alicorn Sentinel said landing by Starfall.

"Brutus, long time old friend." Starfall said looking at the big dark green Alicorn that was built like a body builder.

"He's not the only one still around." Another female Alicorn said who was as white as a ghost said landing next to Atlas.

"Always a pleasure Specter." Atlas said as the four Sentinels and one human stood out numbered before Umbra's army ready to fight.

"Four Sentinels, it seems I'll finish what I started and put your cast down for good." Umbra said drawing her sword and pointing it at Rogue and the Sentinels and her army attacked rushing at the five who opposed their master.

Rogue cracked his neck from side to side and then his knuckles. "Let's kick some ass!" Rogue said kicking off at the army his power flowing from him like flames as he collided with the front line of Umbra's army and immediately started handing out a sever ass kicking to anyone and anything that got close to him.

"Hahaha, I like him he's got spirit, now let's get in there before he has all the fun." Brutus said spreading his wings as he flew towards a pride of Manticores with his warhammer.

"Indeed, let us for fill owe duty as Sentinels, and destroy this evil once and for all." Specter said as she drew her bow and pulled an arrow from her quiver as she flew to cut off a group of the Anubis like soldiers.

"I couldn't have said it better myself." Starfall said readying her magic and despite being the shortest of the Sentinels she went right to the biggest monsters she could see taking them by surprise with her speed and precision.

"Ad Victoriam!" Atlas shouted as he drew both his swords and flew into battle to help Rogue at the front line, the five held the army back fighting with everything they had fighting for days without rest and still they carried on, all the while Umbra grew more frustrated as the army shed spent nearly 20 years building was slowly but surely torn apart by only four Sentinels and one human.

"ENOUGH!" Umbra shouted in rage as she jumped down from the crystal dragon. "Go, kill them all and burn the world with your dark fire." Umbra ordered and the crystal dragon roared spreading it's wings as it took to the skies and unleashed a primordial dark flame scorching friend and foe alike, the Sentinels took cover but Rogue instead flew up to meet the colossal dragon in the skies and he punched it in the center of the forehead with all his might shattering it's crystal scales and sending it crashing to the ground, he landed and charged a kamehameha and fired it at the downed dragon without even thinking about it killing the dragon in one hit.

"Damn, there's no end to these guys." Rogue said dodging and counter attacking an attack from one of Umbra's soldiers.

"Do not falter now, we've finned their numbers greatly and that dragon did more harm to them than us, they can not last much longer." Brutus said getting out of cover and swinging his warhammer taking five of Umbra's soldiers out in one swing crushing them flat.

"Brutus is right, they can't last much longer, we just have to keep up the pressure." Atlas said as he fought thirty opponents at once.

Rogue caught his breath and went back to it fighting a mix of Manticores, Timber Wolves and Moorwens. "Ok, let's go the distance." Rogue said as he breathed heavily quickly ripping the air from the longs of the Manticores setting the Timber Wolves on fire and electrocuted the Moorwens with lightning.

"Damn, they just keep coming." Starfall said as she was surrounded on all sides and was about to be attacked when a volley of arrows and magic dropped Umbra's soldiers as well as other groups of soldiers and monsters, Rogue and the others looked to the direction that the arrows and magic had been fired from and saw a great force of Royal and Night guards being led by Princess Celestia and Luna with Twilight and the others there as well.

"Look who decided to show up, your late to the party." Rogue said quickly taking out a few more monsters.

"Huh, looks like the cavalry finely showed up." Atlas said quickly killing a group of monsters with his twin blades.

Twilight came over to Rogue. "Are you alright, we came as soon as Rarity told us what happened at the wedding." Twilight said trying to move Rogue from the battle.

"Get off me, I've still got plenty of fight left in me." Rogue said pulling away from Twilight's grip and fired a magic blast at a Manticore that tried to attack.

"Regroup!" Atlas ordered and the other Sentinels converged on Celestia's position, leaving the three Royal Alicorns speechless at the sight of the last four Alicorn Sentinels.

"I didn't know that there were other Alicorns out there." Celestia said looking at the four armor clad Alicorns.

"I am Atlas Flame of the Sentinels, and these are my brothers and sisters in arms, Brutus, Starfall Redeemer and Specter." Atlas said introducing himself and the other Sentinels.

"We believed that the Sentinels were long since whipped out." Luna said admiring the four warriors from a forgotten time.

"Not whipped out, just forgotten." Brutus said as he pulled out a second warhammer.

Twilight raised a hand. "What's a Sentinel?" she asked unfamiliar with the term.

"A Sentinel is a warrior that hunts evil and destroys it." Starfall said crossing her arms.

Rogue didn't regroup with the rest and kept fighting making his way to Umbra one opponent at a time, he didn't stop until he found Umbra trying to get away. "Umbra, your not going anywhere." Rogue said ready to face Umbra once and for all as his alias regrouped and rejoined the fight putting up a more formidable fight than before.

"Is that so, well I have something that might just change your mind about that." Umbra said throwing something to Rogue that he caught and looked at and his eyes went wide as he looked at a heavy silver necklace with an arrow head shaped piece of light blue crystal on it.

"How.... how did you get this?" Rogue asked remembering the necklace well since it belonged to his father, he remembered it more clearly than his father's face because he always used to play with it.

Umbra smirked as her curved horn and she took on a human disguise that made Rogue's blood boil. "YOU!..... your the one who killed my father!" Rogue shouted as his power began surging with his rage.

"What's the mater little Rogue, don't you want to give your step mother a hug after all these years?" Umbra said with a sadistic smile on the verge of laughing as she dropped her disguise.

"I'LL KILL YOU!!!" Rogue shouted and he attacked Umbra throwing a punch charged with his magic and elemental power, but she put up a shield that was shattered by Rogue's fist as his punch connected to Umbra's face sending her flying. The others saw and heard what happened as Rogue began his attack on Umbra smashing through her defenses like Broly on a rampage but he was still in control and his eyes stayed blue even as he attacked with the intent to kill.

"Did I just hear that Right?" Rainbow asked looking to the others.

"Umbra is his step mother, and she killed his father." Twilight said in disbelieve. "But how, how could Umbra have been on Earth back then and come back to Equis?" She asked looking to Celestia and the Sentinels for an answer.

"Umbra has a special magic artifact in her possession called the Master Key, it let's the user open gates to other worlds, Umbra has been using it to travel between worlds for thousands of years." Atlas explained.

"I've never heard of this Master Key before." Luna said looking at Atlas with a confused expression.

"After Umbra stole it she removed all mention of it from written record but we Sentinels are well versed in spoken lore, thus we remember it." Brutus said as he brought both his hammers down on a Timber Wolf.

"But why would she kill his father?" Twilight asked.

"Take a wild guess, it's his latent power, Umbra must have wanted his rage and hatred to turn him evil so she could use him like a weapon." Starfall explained.

"Now that just a'int right, killing somepony's pa just to mess with em." Applejack said as they watched Rogue give Umbra an absolute beat down, Rogue rushed at Umbra throwing punches and kicks at her at high speed hitting her in the face body and head knocking her back time and time again all the while not letting his rage get the better of him. Umbra used a magic repulse to push Rogue back as she reached into her pocket and Put the Alicorn amulet around her neck and drained the crimson diamond of all its power becoming more powerful than anyone could imagine, Rogue recovered and attacked Umbra again but just as he got close Umbra used a powerful magic blast at point blank range hitting Rogue and sending him crashing back through nearby buildings.

"ROGUE!!!" The main six shouted as they saw him get blasted back and not getting up.

"Look alive Sentinels, Dark Lord heading this way." Brutus said taking a defensive stance Umbra rushed at the main six the Princesses and the Sentinels as all new dark power surged through her body giving her a high like none other, Umbra collided with a shield that Atlas and the other sentinels had put up and shattered it lashing out at the four Sentinels with blades made of shadow stabbing through the weak spots in their armor and throwing them around like rag dolls before tossing them away and going for Celestia and Luna.

"Princess Celestia!" Twilight shouted as Umbra grabbed her by the throat.

"I've been waiting for this ever since you sent your student to kill my brother." Umbra hissed, she then looked at Twilight. "And don't worry you little slut, I have something special planned for you and your friends and as for that baby dragon, well let's just say its been a while since I enjoyed some dragon soup." Umbra said in a cruel tone as she pulled out a knife and stabbed Celestia in the gut and dropped her like a sack of potatoes, Umbra then looked at Luna and charged a ball of black magic only to get hit by a fusion blast of Fire, Water, Earth, Stone, Ice, Wind, Shadow, Lightning, Metal, Wood and Light hurting Umbra badly.

"Hey, get your fugly ass back over here bitch, we a'int done, not by a long shot." Rogue said as the eleven elemental powers flowed around him as his magic aura flowed over him like fire.

"I'll give you credit boy, you can take more of a beating than your father." Umbra said trying not to show just how much his attack had hurt her.

"I don't care how strong you become or how many items you use, as long as I still draw breath this fight isn't over." Rogue said as his powers began surging again and even pulsed out word like when he lost control in the Sky View Vail before pulling back in leaving the onlookers speechless.

"It's your funeral." Umbra said charging a dark magic attack and fired it at Rogue but he back handed it away as his hair stood up on end like a Super Saiyan glowed white as his eyes turned metallic gold and in a burst of white light Rogue's hair turned metallic bright silver making him look like a silver recolor of the original Super Saiyan with gold eyes as silver energy now flowed over his body. "WHAT!" Umbra shouted as everyone looked on at Rogue's new form.

"Your not dealing with a human anymore Umbra, Your now dealing with the first Fusion Elemental." Rogue said as he powered up making a beam of his energy shoot into the sky like a pillar blowing away all the clouds.

"You think this changes anything, I still have the power of the Alicorn amulet and the crimson diamond, what can you possibly do to me." Umbra said smugly. Rogue smirked and vanished moving thousands of times the speed of light and kicked Umbra into the nearest mountain completely destroying it, Rogue then smirked and flew after Umbra reaching the sight of the destroyed mountain in only 0.000,000,001% of a second and landed in a spot where he could look down at Umbra. "How is this possible, nopony can beat me, not when i have this much power." Umbra said as she shakily got back up.

Rogue looked down at her in as if she were less than the dirt on his shoes. "Your forgetting on thing there Umbra." He said.

"And what's that?" Umbra asked.

"I'm not a Pony, I'm the Fusion Elemental, Rogue Winters son of Arthur Winters who you killed in cold blood." He said as his power surged higher and his silver hair glowed white again and grew out down to his shoulder blades still keeping the Super Saiyan like spiky style.

"You think you can beat me because of this new transformation you've achieved, think again I'm Umbra, I've had to deal with worse than you boy." She hissed with venom dripping from every word.

Rogue smirked looking down at Umbra as his Legendary potential allowed his power to constantly increase with out limit. "You want to put money on that, I haven't even warmed up with this power yet." he said with absolute confidence in this power he'd been working towards this whole time since he arrived in Equestria. Umbra faltered as she sensed Rogue's power rising constantly with his potential and she realized she may have bitten off more than she could chew with him, when she even considered that killing his father and bringing him to this world was a good idea. Rogue didn't give her the chance to react as he attacked at faster than light speed and stood behind her, Umbra turned to look at him only for time to catch up with his speed as shockwaves from Rogue's punches exploded across Umbra's body before she was sent flying across the battle filed by a bigger impact.

"I have to... get out'a here." Umbra said using the master key to open a portal to another world and roll through it.

Rogue saw what she did. "Get back here and fight me." Rogue said quickly following Umbra through the portal, on the other side he saw a wasteland and a city of skyscrapers set to a back drop of a sickly green glow, he looked around for a few minuets and found her tracks heading to the city and he powered down. "You can run, but you can't hide." Rogue said following the tracks in the parched earth towards the city.

The End.

Author's Note

And the rest I leave to the imagination of the reader.

Will Rogue find Umbra and finish this once and for all? who knows.
Will he die? that's for you to decide.
