Well, another return... but with a twist. Instead of the addition of Danny Phantom and Avatar Aang, we'll be having the duo of the Heroes United (Ben 10 and Generator Rex) and the Arrowverse's Trinity (Green Arrow, The Flash, and Supergirl) in the world of Bloody Revolution.

Not sure how it will go?

Probably might end in flames to be honest, but it's worth a try... but for now let us begin.

For Ben and Rex, it will begin at the end of the actual crossover (with a bit AU, including Rex will just absorb the Omega nanite back immediately this time around). As for Barry, Kara (I was literally gonna add her in later... but then I was like, what the hell), and Oliver, it'll be during the Invasion crossover, which will have some differences. This shall be fun.

Ch.1 Welcome to Remnant.

Earth-109 unknown town.

Ben Tennyson has had long days before, but the past twenty-four hours have been crazy for him. He had fought a strange machine, and the fight somehow got the two of them sent to a parallel universe.

After landing on this new Earth, he had gotten in a fight with this world's hero, Rex Salazar. The fight spread throughout the city, ending in a stalemate after the machine escaped, and left a friend of Rex's incapacitated.

Ben surrendered and was placed in an energy tube. Only so he could figure out what was going on again... which then lead to his escape. He went to Bellwood, only to face off against Rex... briefly. He then noticed that his favorite smoothie shop was nonexistent on this Earth, confirming he wasn't on his own world.

Rex then agreed to help him, and that lead to their first confrontation with the Alpha nanite, which was the machine he fought to start this mess. Which then attacked them again after he met Rex's brother... who bailed on them.

They then hung out while waiting on the Alpha's location, striking up a bit of a friendship. They then went with this man known as White Knight and fought Alpha in his giant EVO form. Alpha took both the Omega nanite from Rex and the abilities from the Ultramatrix. This resulted in a very terrifying creature.

Ben then went Upgrade and fused with Rex, making Rex's builds even more advanced. They fought the Alpha like that before he nailed him hard enough for Ben to fly off and change back to normal. That lead to Rex firing him through his cannon as Cannonbolt and knocking out the Omega nanite, which was absorbed by Rex.

This lead to the current situation as Rex then proceeded to contain the Alpha in a very well kept sphere. Rex's brother had showed up with a Null Projector of all things... Ben wasn't entirely sure how he made it, but oh well. So right now, the Null Portal is open and Ben was walking up towards the sphere containing Alpha.

"Let's do this again sometime," Ben told Rex as he was about to press the dial on what he wanted. That is... until vines started to grow out of the ground and grabbed the Alpha.

Rex growled as he knew who was responsible. "Van Kleiss," he growled as he formed his Smack Hand builds.

"So much potential in that sphere," said a man with long black hair, and a yellow gauntlet with needles poking out of the fingers. "I think it will... benefit my needs and plans."

Then all around the two heroes, because Rex's brother seems to have bailed... again, came three different EVOs. Ben saw what looked to be a cyborg werewolf, a strange lizard monster with a crystal on it's shoulder, and a four armed girl. "Rex," the Ultramatrix weilder asked, "who are these guys?"

"The Pack," Rex growled, "get Alpha out of here, I'll hold them off."

"No offense Rex," Ben said as he pressed down on the Ultramatrix, revealing Four Arms, "but at your state right now... I doubt you can hold them off by yourself."

"You're sure you can risk it," Rex asked him as they both looked at the portal, which seemed to be holding up just fine... for the moment.

Four Arms nodded. "Now let's see if your villains can thrill me."

The robo-wolf, Biowolf, attacked first as he lunged towards Four Arms, who caught him with his upper arms and then uppercutted him with the lower ones.

Rex went straight for Van Kleiss, but the lizard creature, Skalamander launched diamonds at him. Rex quickly formed his Block Party, keeping the projectiles from hitting him. He retaliated by forming his Slam Cannon and firing a few projectiles of rock and metal at the enemy EVO. He then had to activated his Boogie Pack to fly out of the way of vines sprouting out of the ground.

Back with Four Arms, he was exchanging blows with Biowolf before the four armed girl, Breach, fired red portals towards the alien hero, who just merely rolled out of the way. He then charged for the girl, but before he could reach her, Biowolf tackled him away from her, keeping Ben from keeping full focus on one opponent.

With Rex, he had just chopped down several vines with his Bad Axes build and had knocked Skalamander away with his Punk Busters as he faced off against Kleiss. "What do you want with the Alpha nanite," Rex demanded.

"A strong nanite needs a strong host," Van Kleiss stated simply, "who better to be the Alpha then... the leader of The Pack."

"Yeah," said the voiced of Ben, now as the fire based humanoid known as Heatblast, "I don't think so." He struck Kleiss with a blast of fire before Rex followed up with a right fist with the smack hands, sending him towards the portal.

Before they could close in though, Breach jumped from behind them and sent breaches flying at them. Both heroes managed to roll out of the way, but the breach struck something else.

When the breach struck the portal, something seemed to happen as a shockwave happened after the impact, sending the group flying. When Ben and Rex regained their footing

"Whatever happened," Ben said as the portal started to expand, "it's not good!"

Then as the portal overtook the two heroes, Ben gave a sorry expression towards Rex. He knew that he was going to have a similar feeling as he had when he arrived on Rex's Earth when they make it to the otherside. Then he saw nothing.

Earth-1 Central City

Oliver Queen, also known as the Green Arrow, has had a long couple of days. It started with him and Dig about to finally get a the criminal known as Vigilante behind bars, but before they could be laid out by bullets, Barry Allen, also known as the Flash, ran through and grabbed them.

Barry then proceeded to ask for help in regarding an alien invasion, which of course he accepted. They then called in the Legends, and Barry brought in a friend from a different Earth. An alien known as Supergirl, also known as Kara Danvers. Oliver won't lie, she unnerved him, and he hated that feeling.

Barry then revealed he changed the timeline, making an alternate one where his family was still alive, which made most of the other Earth Oners distrust him a bit. Barry tasked Supergirl to lead them on a lead while Oliver stayed and talked to Barry.

Then their was the whole deal with him and Barry fighting the entire team, who were then under mind control. Soon after that, all the non enhanced individuals were taken onto the alien ship and placed in a dream world.

They managed to bust out. The aliens then demanded that if the Flash handed himself over... they would leave. Oliver and Kara managed to talk Barry out of it, with Oliver also accepting Kara's help. That lead to the confrontation that held the current battle.

Currently, they were all in a city wide fight, the Dominators, as they are called, decided to make this fight a city wide brawl. Oliver had to call the full team from Star City to help and even with that, it seemed to be difficult.

Right now, he was facing off against a squadron on his own. Dodging strikes and firing arrows is not an easy feat to do when the aliens have more strength and are slightly faster. He was then grabbed and slammed down onto the hood of an abandoned car.

Before the Dominator could continue, a red and blue blur slammed into it, before proceeding to slam her fist into several more sending them back. Oliver looked up to see Supergirl standing there looking at him. "You alright?" she asked the archer.

He was silent as he fired an arrow which sailed past Supergirl and nailed a Dominator in the head. "Yeah, I'm good," he said with a nod as she nodded back. Just then. Flash sped in taking out three incoming Dominators.

"These things just keep coming," Barry said as he leaned against the car.

Oliver pulled an arrow out of a dead Dominator before placing it back into his quiver. "We're not giving up though," he told the speedster confidently.

"I knew you'd say that," Barry said with a smirk.

"Boys," Kara said, gaining their attention as she turned and smirked at them. "Ready for another bout?" she asked.

"You getting sleepy," Barry joked as he stood up and stood beside his two friends as they saw what's coming.

The three stood side-by-side as an even larger squadron charged at them. "You two ready," Barry asked, getting into a running stance.

"Do you really need to ask, Barry?" Oliver replied with an amused eyeroll, gripping his bow and reaching for an arrow. Even though his muscles were aching, he was going to fight, at least he has these two watching his back.

Supergirl smirked as she started to hover. "We're always ready."

The three heroes then charged in. Supergirl taking flight while Flash took off running. Whichever one's that made it pass the super strength and heat vision of Kara or the super speed of Barry, met the arrows and skills of Oliver. They were like a well oiled machine as the three tore through the squadron, unknown to them, that one of the Dominators had a special present for them.

As they were to busy fighting, the Dominator threw a special designed grenade of unknown purpose that landed right infront of them. As the three were to busy fighting off Dominators to notice... the grenade went off in a flashing light that lit the street up.

When the flash of light disappeared... The Flash, The Green Arrow, and Supergirl were gone.

Universe Unknown, World of Remnant.

Rex slowly began to regain consciousness, he had absolutely no idea where they were. Ben probably didn't either... he looked up to see they were in some kind of forest.

"You okay Ben," Rex asked as he began to sit himself up.

Ben, who layed on his stomach, groaned as he began to push himself up. "Yeaaahh," he said with a groan, "I've had worse... what happened though?"

"I don't know, but it seemed like when Breach's portal struck the Null Void portal..." Rex started.

"... took us somewhere different." Ben finished. "Is this on your Earth though?"

The EVO decided to give it a shot. "Holiday? Bobo? This is Rex," Rex sai, but all he got was static. "Nothing, how about you?"

Ben then activated the communication settings on the Ultramatrix. "Gwen? Grandpa? Kevin? Anyone getting this?" He had the same result as Rex... more static.

"Well that's just great," Rex said as he stood up.

Ben nodded as Rex helped him up. "Do you think The Pack's here to?" he asked.

"If they are," Rex answered, "I'm going to find them."

Ben crossed his arms. "You mean 'we', I'm not on my Earth either, and it's because of those freaks we're stuck on this one."

"You think you can handle a group of EVO's and the possibility of an army if they're is a civilization. Which most likely will be knowing my luck," Rex brought up.

Ben smirked. "I beat you did I," he joked.

"It was a draw at best, but I'm pretty sure I won," Rex stated with a cocky grin of his own.

Ben kept his smirk. "I think we can settle that later."

"I think we will, Ben 10," Rex agreed, "but right now, we better move." Ben nodded in agreement as they began to walk off.

They both stopped in their tracks when they heard groaning from behind. "You've got to be kidding me," Ben said as the two started to turn around, expecting to see Van Kleiss and the Pack. Instead, they had a slightly less strange sight.

Still strange though.

The first one was the teen that looked to be a year older then them in the emerald green suit. He seemed to have a quiver on his back and a bow in his hand. Over his head was a hood, but it appeared that a mask was also over the upper half of his face.

Laying beside him was a teen in a dark red onesie suit. On the chest was a white circle with a yellow lightning bolt on the chest. He had a mask over his head covering all but his mouth, nose, and eyes.

Lastly, laying on the otherside of the green guy, was a blonde teen girl. She was in a red and blue suit that had a red skirt and boots, and a blue top. She also had a red cape on her back, and lastly on her chest was a red diamond with a red engraved 'S' within it.

Ben had to admit, she wasn't that bad looking. Rex noticed and smirked. "Mi amigo, it's weird checking a woman out while they're unconscious."

"I'mnot checking her put," Ben defended, but was blushing in embarrassment. He quickly shook it off as he then wondered who they were. "You recognize them?" Ben asked Rex as they looked the three over.

The EVO shook his head. "No, and I know they weren't with us when the explosion happened."

"Then how'd they get here," Ben wondered. As he went to check on the other teen in green, his wrist was grabbed and he was judo thrown. He got up with Rex getting sent back.

"Who threw you back," Ben asked as Rex got to his feet.

Rex looked up. "The blonde," he said simply as the three others began gaining their footing. They looked and saw that the three unconscious teens are not so unconscious anymore. Better yet, they look ready to beat them senseless. What else is new.

"Who are you," demanded the teen in green as he aimed an arrow at them.

Rex and Ben looked at each other before sighing. What a day. Then something strange happened when the teen in red spoke up. "Uh... why does your voice sound younger?"

"Did you here yours," the woman asked before gasping in shock, "and mine!?"

"We can discuss what's happened later," the hooded figure said.

Both EVO and Ultramatrix wielder looked at each other confused as they began to whisper a plan of some kind. "What do you think," Rex asked.

"You take the guys in green and red, I'll take the girl," Ben suggested.

Rex rolled his eyes. "This isn't the time for hormones, dude," he told Ben.

"I know, but it's always the women that have the deceivingly powerful stuff," Bek said in full seriousness.

Rex had to sigh, he wasn't wrong, that's kinda how it goes. "Fine, but we should probably attack first, in case-"

"In case of what," the woman yelled out.

Rex and Ben looked at each other confused. "Uh... how'd you hear us?" Ben asked.

"Doesn't matter," the hooded teen said as his side began to walk forward. "We just want answers." The red teen began to get into a running stance and the blonde believe it or not began hovering, and her eyes glowing blue.

Both boys sighed as they saw where things have been going. "You know, we've not had a really good day," he said as he activated the Ultramatrix.

"So you've gave us the perfect way to blow off steam," Rex said as he pounded his fists together.

The boy in red smirked. "You really think you can beat The Flash, Supergirl, and the Green Arrow?"

"You really gave out our names like that," the boy in the green hood asked him.

"I guess we better introduce ourselves," Ben said with a smirk. "The name's Ben 10, but you can call me..." He then pressed the dial on the Ultramatrix and turned into a silicon based lifeform that resembled diamonds, "Diamondhead!"

"And the name's Rex," Rex added as his arms shifted into giant robotic fists he calls the Smack Hands, "now thrill us!"

So now that the Man of Action duo and the Arrowverse Trinity are on Remnant... interesting am I right. It also appears that Barry, Kara, and Oliver have been de-aged. Wonder how that happened? The answer is Fan-Fiction. Three other heroes will join them eventually (Two boys and a girl), and I know that I have one boy confirmed and how to put him in as well. So please send me your opinions of who I should place in later on.

Anyway, what happens when heroes meet that absolutely don't know each other and are confused at where they are?

They punch what they don't understand! (Unless you're Barry and Kara from when they first met.)

Anyway, the next chapter is the face-off and then the team-up of the two groups... how will it go? Should be entertaining, but find out next time. Here's a question, are Grimm made by dark magic, and if so should they be able to harm Kryptonians?

As for pairings... Rex/Weiss, Barry/Yang, Ben/Kara, Oliver/Blake and Ruby's pairing will be a surprise for you all.
