Ah, Net City. A place full of wonder, potential new friends, great new sights, and home of some of media's powerful beings.

*VROOM!*

Just, y'know. If you were in a universe or timeline that wasn't a setting right out of Flashpoint meets Days of Future Past.

A group of heroes were riding on top of a pickup truck carrying supplies, fending off Xenomorphs, Tarkatans, Joker Henchmen, Red Skull Henchmen

Green Arrow took a shot at a Xenomorph, "Ugh! Ugly motherfu- oof!"

Blake shot at the Xenomorph that had pinned Olivier down, "Careful. We're just here to disrupt Red Skull's supplyline to getting more ammunition for his troops."

Hawkeye aimed and shot a putty arrow at a Red Skull soldier, "Ugh, seriously! The guy's a freaking Genocidal maniac who's proud of being a Genocidal Maniac and even freaked OTHER genocidal maniacs out. Why would anyone with a decent moral compass follow him?"

"Some people just feel like they're losing out in the long run, so they side with the first person who promises them power over the ones they feel threatened by." Blake answered.

"Doesn't change the fact that they sacrificed their morality and credibility to no longer feel threatened." Cheetara countered, using her staff to impale some Tarkatans and send them flying to some of Joker's henchmen.

"At least Joker doesn't discriminate." Green Arrow noted as he saw that the henchman was a Lin Kuei member, "Red Skull only accepts white dudes as henchmen. Heard he shot a Tarkatan for being 'inhuman scum.'"

"Only an idiot would say that a guy with arm blades is useless because they're 'impure.'" Master Chief said as he took down some more Xenomorphs with his sniper, "Seriously. The Marines sided with the Covenant for a while to beat a common threat after we made peace."

"Why did people side with Skull, again?" Spawn asked, shooting one of Hydra soldiers through the head.

"Maybe they felt threatened by people who follow the 'cornered cat' mentality, pardon the expression." Chief muttered.

"Adam threatened any deserters with death. Maybe Skull did the same." Blake mentioned, "Aside from that, we have bigger things to worry about."

Cheetara nodded, "Hawkgirl, what's the status of the barricade?"

"Lanterns are having difficulties to put it lightly. Apparently, some Facehuggers got to some Doombringers, and are giving them some trouble. Can our archers do something about it?"

"Get us in range, and we have some arrows for the situation." Green Arrow responded.

"Step on it, Rock!" Blake called out, "We have fliers incoming!"

"You heard her!" Dinah called out, "Put the pedal to the mettle!"

"Uh oh…" Green Arrow realized.

"Ollie? What's going on?" Canary asked.

*BOOM!*

Mega Man looked in his rearview mirror and his eyes widened, "Crap! Doombringers. We have only a few miles to go until we get in range of the barricade, think we can handle it?"

"It's either the Doombringers or the barricade. We don't have enough arrows for both of them."

"For the love of-" Dinah unbuckled her seatbelt and opened the door.

"What are you doing?"

"I'm going to sing a few show tunes for these things." Black Canary answered. She maneuvered her way to the top of the truck, kicking some Hydra Henchmen along the way.

"Dinah? What are you-"

"Might want to cover your ears."

The others took the cue and held their hands over their ears. Master Chief simply turned off the audio input on his helmet. In Blake's case, she had covered her cat ears herself, and Master Chief took the courtesy of covering her human ears.

"*SCREETCH!*"

Dinah's Canary cry knocked all of the airborne opponents out of the sky, and those that were on the ground wound up sprawled on the ground.

"*cough cough!*"

"Dinah!" Oliver rushed over to his wife's side, "You okay?"

"Yeah." She replied, "I'll just need some water later. *cough!*"

"We're closing in on the barricade! Hawkeye! Arrow! Get ready!" Mega Man called out.

"Think you can make that shot?" Hawkeye asked.

"These old bones haven't failed me yet." Arrow quipped back.

"Then let's do it."

"BILLION ARROW BOMBING BARRAGE!"

Hawkeye's Pym Particle arrow flew first, effectively taking down or incapacitating any Doombringer Xenomorph that was there.

Green Arrow's shot came next; he fired his megaton arrow to cause some damage.

Hawkeye had already fired his 30-Megaton bomb arrow when GA's arrow had detonated. The resulting explosion caused the barricade to turn to rubble.

"One more shot." Green Arrow muttered, firing his Tornado Arrow to clear the debris and make a clear pathway.

"Lantern Team! You guys alright?" Master Chief asked via the comms.

"Doing alright. Just need to get back to base for a recharge."

"See you there, Indigo." Chief answered, looking at the horizon, "Chief out."

"These drones of Braintron are nothing more than mindless beasts, now my bloodlust shall feast!" Etrigan the Demon tore apart a few Doombringers with his claws.

Hellboy grunted as he punched a hole through another drone, "I still don't know why that robotic asshole wants this area so much. All it's filled with are brain-dead humans that are just Xenomorph chow, and potential cannon fodder for Joker and Red Skull."

"GRAHH!" Guts cleaved through several drones, "Less of these bastards, the better."

"The Black Knight of the Hawk has a point here. Though I'd simply settle for getting Jason out of my ear." Etrigan replied.

"That was a little forced."

"You try thinking of rhymes that others would want to hear. For the love of Merlin, I'm not Shakespeare."

"We got word of your need for a substitute. We're sending in Iron Man's Iron Legion."

"So they finally finished charging." Hellboy grunted, "Took long enough."

"Get back to base soldiers. We need to get our 'master plan' as Wade puts it figured out."

A few hours later…

"So, it wasn't too much trouble?"

Piper shook her head, "Nope. The guy wasn't seen that much."

"Weird. Nothing?"

"Not even a roar of anger or anything. Like," Piper trailed off, "He just disappeared."

"Here's that kryptonite power cell Rick needed." Zero said, handing Wade the device.

Wade rubbed his chin, "That's never a good sign. What about you guys?"

Selena shrugged. "A close call from… Her… but nothing other than that." she shuddered.

"Here's your Time Portal Fragment. Why that monster had it in the first place is beyond me, but regardless, it should help to keep any of this from happening." Hanzo said, handing the relic to Deadpool.

"He probably had it to torture Jack with." Wade figured, "Like, tell him that if he can reassemble a time portal, he could return to the past."

"That's quite the elaborate way to try to get vengeance." Hanzo muttered, "And I should know. vengeance was my entire drive for a while."

"At least you got your head together." Raven said, entering the room.

"You got the device?"

"Sorta…" Iron Man said, "Braintron got enough parts to repair his ship, but we managed to get some scrap parts. Here's hoping that it's enough to lock onto that timeline that Rick keeps blabbing on about."

"It better be enough. We're going to have a full-on war between us and Brain Troll if we can't get that machine up and running."

"We also got another souvenir to give us an edge to beat the bad guys back with." Tucker mentioned.

"What? The matrix of Leadership?"

"How'd you guess?" Kurt asked, disappointed that the surprise had been ruined.

"The fact that Braintron's drones are blasting at our shields." Wade pointed out.

*BOOM!*

"Yeah, it's not just Braintron and his drones." Nova rushed in, "It's everyone."

The view was something out of an action film. Just replace all the heroes with various villains and monsters all converging on the hole-in-the-wall base that the heroes set up as a small resistance base.

"ATTENTION LESSER BEINGS!" Braintron's legion-like voice echoed, "YOU HAVE ONE OF YOUR EARTH HOURS TO RETURN WHAT WAS STOLEN FROM ME IN EXCHANGE FOR A SWIFT AND PAINLESS DEATH; OR YOU CAN RESIST AND BE MET WITH YOUR PAINFUL DESTRUCTION." Braintron appeared in the front of the base, "Please. Resist."

"Why are they working together? They shouldn't be working together!"

Everyone was in a panic. Nobody could remain calm. "We're under attack!" Tails cried out.

"I had plans for if two or three were to team up, but none for all of them at once!" Piper cried out.

"Everyone! CALM DOWN!" Deadpool called out, "I can't believe I'M the voice of reason here."

*BOOM!*

Everyone fell over in a panic.

"Ah shit…"

A dark shadow enveloped the sights of the people living in Starbase Mk V.

"…Aku."

"Now, foolish heroes. You shall all kneel before my might, and you will be killed."

"Don't you mean 'or you will be killed'?" Jaune asked unhelpfully.

"NO." Aku's voice bellowed, the shockwave knocking those unprepared over again.

"You had to ask." Sonya glared.

"We don't have enough time." Deadpool stated, "Rick, what our ETA on that dimensional time machine?"

"We have everything almost set up. We just *uurp* need to sync up everything and send Clone Boy back and stop all this from going to shit. Give us five minutes"

"You have three." Guts grunted. He picked up his sword, and started towards the door.

"Where the hell do you think you're going?"

"Like hell I'm goin' out like a coward." Guts growled, "If I'm going to die, I'm going to die the way I want to go out."

"You'll die out there."

Guts was silent for a moment, "You can't stop me. I'm killing that four-eyed demon."

"Then at least let people help." Raven requested, "Trigon is my father. I should have a hand in his demise."

"Like hell I'm letting you go in without me." Hellboy said, "Count me in."

"Same here." Ghost Rider added.

"I'd like to see that guy catch me." Rainbow Dash boasted, "Don't leave me out of it. I'm basically a magical relic anyways"

"If one of my subjects is going, then it is my duty to protect them." Celestia stood up, "I shall also accompany you."

"Trigon must be stopped." Optimus said, hope and determination back in his voice, "No matter the cost."

"I got nothing better to do…" Spawn shrugged.

"May as well show my faith by fighting a demon." Kurt shrugged.

Deadpool waited a moment, "Oh. Is that it? Is everyone who stood up going after that bastard?" He asked, "No offense Raven."

Raven chuckled a bit, "I would have thought that you'd call him worse. But I believe that this may be it."

Deadpool sighed, "None of us are going to convince you that this is all suicide and that you shouldn't do it, are we?"

"No." None of the people who decided to stand up to Trigon hesitated when they all replied.

Wade looked out the window. There was still some time to hold the line. Perhaps there could be some light that shined in this world.

"Okay." He turned to the others.

"What?" Jaune asked, "Are you seriously going to tell us that we need to go out there? - I already lost enough people in my life, thank you very much."

"Then you aren't cut out for the real world, kid." Frank said, "I lost my wife and children, and I still go out to keep the city clean of criminal scum every day. But you?" He gestured to the swordsman, "You only lost someone you barely paid attention to. That was your only personal loss. Everyone else here lost more than you, more than once, and we still go out there to fight."

Jaune was at a loss for words.

"So make your decision. Live and hide, or fight and die."

"Your girlfriend chose the second option. But considering that you couldn't be bothered to even try to save one of your other friends after bemoaning losing everything earlier, I guess it's no surprise that you can't be bothered to try when it's the whole world at stake." Deadpool sneered.

Jaune sighed, "Fine. I'll go."

"Such fate is fickle and crude, you should probably change your attitude." Jason Blood muttered, "Heh, Etrigan must be rubbing off on me more than ever."

"That demon is indeed clever." Pinkie added.

X: So, y'know how I said that there was a list of alternate timeline battles? Well, there's also a Q&A segment that might answer some of your questions as well. In the meantime, this is where we get ready for the climax… 's setup.
