A/N: Welcome to the next epic crossover I'm writing! As the description suggests, this is a giant crossover of The Boys tv show, the MCU, and the Arrowverse, as well as crossing over with other properties, whether in really big ways, or just small cameos.

I'm only planning on covering the first two seasons with this one, then deviating with my own ending after the finale for season 2 drops. I might dump the season 1 chapters right away, or at least daily, then the season 2 episodes weekly, or until the season ends. I'm not sure right now.

There's a lot of changes I already make to some scenes from the show. Some, I fast forward. Others, I skip out entirely, because I don't wait to have fifty page chapters. Anything that's cut out or skimmed over quick, I did it because I felt it didn't contribute to my overall story.

Oh yeah, the Prologue is really heavy about how the multiverse changed due to Crisis from Arrow, and the Snap from Infinity War, but the rest of the story won't be a huge multiverse verse hopping adventure. I might send one or two characters to space though.

Last thing, make sure to read the end notes for some clarification on some parts of the story. And instead of listing song titles at the very beginning, I'm going to experiment by placing them at different moments of the documents.

All set? Enjoy!

The multiverse is a fascinating concept. The idea of multiple different universes, each with their own unique changes and events. Any small occurrence, such as stepping on an insect in one reality, and it completely changes the outcome of the individual.

There are many key differences between our reality and others. For one, the individuals of our world are just normal humans, mortal. Across the universes, there are heroes, and villains, with superpowers. None of them exist in our reality, aside from the form of television, movies, and comic books.

That all changed when monumental incidents occurred across the dimensions, relatively at the same time. In one corner of the multiverse, dubbed Earth-199999, the mad tyrant Thanos gained ultimate power by assembling the six Infinity Stones and snapped his fingers, exterminating half of all life in that universe. In another universe, one that called itself Earth-1, a being called the Anti-Monitor wiped out the entire multiverse in an anti-matter wave. However, with the combined might of its heroes, including the Flash, Supergirl, White Canary, and Oliver Queen, revealed to be the Green Arrow a year prior, they reset the multiverse by creating a new universe that combined several worlds. Both cataclysmic events, despite occurring in separate universes… it was like a second Big Bang. Both those universes, as well as several others, were combined into what became known as Earth Prime. And the world was never the same.

In this new timeline, after Tony Stark sold Avengers Tower, the building was quietly bought by a company named Vought. At the time, they were relatively unknown despite having been active since the 1940s, but quickly gained a reputation of having their own heroes, forming a team named the Seven. The supes weren't a new idea, and each of these individuals were already well known shortly after the Battle of New York, but their own superhero team seemed to take off in the wake of the Avengers. When the Seven was formed, they included the "supes" called Homelander, Queen Maeve, the Deep, Jack From Jupiter, the Lamplighter, Mister Marathon, and Translucent. This was shortly after the Avengers' falling out in Berlin, which led to Thanos gaining the Infinity Stones two years later and wiping out half of all life.

Three weeks after what the media described as "the Snap", Homelander used his super hearing to spy on the remaining Avengers' plan to find Thanos, deciding the Seven would join them to avenge those lost. After some shaky introductions, the Seven and the Avengers, minus Iron Man, boarded a spaceship that an anthropomorphic raccoon called the Milano, and made a hyperjump through space.

Music: "Porch/End Credits" From Avengers Infinity War

Once they were in deep space, Captain Marvel and Homelander exited the Milano, careful not to let anyone get sucked out into the vacuum.

"I'll scout." Carol volunteered, looking back at the ship's cockpit.

"I'm coming with you." Homelander quickly declared, and the two superhumans flew towards the planet's surface. A minute later, only Captain Marvel returned.

"Where's Homelander?" Captain America asked.

"He said he's still scouting, but there's no one there." Carol told everyone. "No defenses, nothing."

"And that's enough." a blue skinned woman, Thanos' daughter Nebula, said in a whisper.

"I'll go catch up to our new 'friend'." Carol decided, and flew back down to the planet, with the Milano speeding after her.

Thanos walked through his field, stopping to pick up a ripe, golden fruit, when he suddenly looked up, seeing a blue streak in the sky. A second later, the titan felt something slam into his chest, sending him to the ground. He looked up, seeing a man in a red and blue suit standing on top of him. Seconds later, a woman in a battle suit of similar color flew down next to him, her blonde hair flowing freely. This one, he knew of. There was talk of a Kree warrior powered by the Tesseract, calling herself Captain Marvel.

The woman picked Thanos up off the ground and put him in a headlock, just as Milano touched down onto the planet, with the Avengers and the rest of the Seven walking down the ramp. The god in the red cape, called Thor, flew over to them and swung his axe down, cutting off the arm with a golden glove worn. The raccoon went over and turned the glove, only to gasp when the Infinity Stones weren't there.

"Oh no…" Rocket Raccoon murmured in fear, looking up at Thanos.

"Where are the stones?" Captain America asked, looking at the mad titan. When he didn't speak, Carol growled in his ear.

"Answer the question."

Still, Thanos didn't say anything, only groaning from the headlock, as well as two of the Avengers in suits of armor restraining him. Homelander was beginning to get bored, so he stepped forward, allowing his eyes to start glowing red.

"Tell us wear the damn stones are, or I'll laser your fucking face off!" the leader of the Seven threatened, getting up in Thanos' face.

"They're gone." the titan revealed. "The universe required correction. After that, the stones served no purpose, except for temptation."

"No, that can't be true." the individual wearing the bulky red and gold armor stammered, temporarily letting go of Thanos.

"He has to be lying." the other metal man, this time wearing a black and gray suit, could be heard murmuring.

"Where are the stones?" the woman in the black suit with stark blonde hair, calling herself Black Widow, asked again.

"They're gone." Thanos repeated. "I destroyed them-"

"Oh, fuck this!" Homelander yelled, shooting lasers out his eyes and jerking his head to the left. The action resulted in Thanos' head being completely cut off, as well as the top part of Carol's head being turned into mush. Both bodies crumpled to the ground, their red and purple blood mixing into the dirt.

"What did you do?!" Rocket exploded, looking up at Homelander.

"I killed the bad guy. What did it look like?" Homelander rolled his eyes.

"We needed him to tell us where the stones were!" Black Widow chastised. "That's the only way we could undo all of this!"

"He said it himself, the stones were gone." Homelander shrugged.

"You idiot, he could've been lying!" the man in the red and gold armor roared, pushing Homelander. The supe barely even felt it, but nevertheless became miffed, and activated his laser eyes, burning a hole through the armor and also decapitating Black Widow in the process.

"Bruce!" the other armored hero yelled, holding up an arm and fired an energy beam from his hand. Homelander simply looked in his direction, and the lasers cut through his armor as well, bisecting the man inside. Due to his reckless direction of the lasers, they also cut cleanly through the blue skinned woman.

"What are you doing?!" the raccoon, jumping up and trying to attack Homelander. All he was met with was a fist to the face for his trouble, and his blood and brains flew across the field.

"Friend Rabbit!" Thor yelled, jumping up and preparing to cut Homelander in half with his giant axe. The so called hero directed his lasers upward, attempting to melt the weapon, but opted to sidestep out of the way at the last second. As Thor embedded the axe into the ground, Homelander grabbed the sides of his head and lasered directly into his eyes. The god of thunder screamed, as the beams tore through his head and liquified his cranium.

Homelander exhaled from the massacre he carried out, and looked back at the final Avenger standing: Captain America.

"Are you going to attack me too?" Homelander challenged.

"I can do this all day." Steve Rogers narrowed his eyes in anger. "You wear the American flag as a cape, but you're no hero. You're just a psychopathic killer who will kill anyone in your way. Just like Thanos."

Homelander narrowed his eyes as well, and lasers shot out. Steve quickly dove forward, before coming up from the left and activated the Wakandan shield he was given weeks ago, and slashing it across his face. Homelander stumbled back, and touched his cheek, feeling a fresh cut there. He pulled back, seeing the crimson fluid of blood on his already red gloves.

"Huh. I actually felt that." Homelander muttered, before grabbing Rogers by the throat. "Shame I gotta kill you too. I kinda saw us being similar."

"We… are nothing… alike. And… there will always… be those… to stop… you..." Steve wheezed out. Homelander wore a bored expression, tightening his fist and popping the Captain's head clean off, as if pulling the cork off a bottle. As he tossed the headless body away, blood fell onto Homelander's face.

"Aw, fuck." Homelander complained. "Now I'll have to wash this out of my suit."

He looked back towards the Seven, who simply stared at him, horrified.

"That's what you're worried about?" Mister Marathon asked. "You just killed the Avengers!"

"Hey, in my defense, they attacked me first."

"After you killed Thanos!"

"Come on, he's the bad guy, we stopped him, what's the big deal?!" Homelander asked.

"The big deal is that we don't have any way to bring the people we lost back!" Mister Marathon roared, stepping closer to Homelander. "Vought sent us to help them save everyone, in order for our first public appearance to skyrocket in profit! What are we going to do now that you've fucked it up?"

Homelander's hand formed a fist, and he punched his arm right through Mister Marathon's chest and out his back, to the shock of the rest of the Seven. The dead speedster's body crumpled to the ground, as the leader of the supes looked back to his team.

"Does anyone else have something to say?" Homelander asked, his eyes beginning to glow red hot once more. The rest of the supes, clearly terrified, shook their heads. "Good. Now let's get back home."

"But how are we going to explain this to Vought… to the world?" Queen Maeve asked, her hands on her hips. Homelander simply smirked.

"Leave that to me."

"It is with great sorrow to tell the world… that the Avengers were murdered by Thanos."

Homelander hovered above a crowd of people in the city of New York, with a podium below him. Behind said podium were Queen Maeve, the Deep, Translucent, Jack From Jupiter, Lamplighter, and a new speedster named A-Train who used to lead the group Teenage Kix before the Avengers were even formed. It had been a few days after Homelander killed Thanos, and in that time, he found the perfect replacement to take Mister Marathon's spot in the Seven.

"We were there to assist Earth's Mightiest Heroes, but we were too late." Homelander said, feigning sadness. "I watched it myself, as Thanos crushed Captain America's head with his bare hands."

Amidst the speech, Queen Maeve hung her head. Something was eating at her soul, but it was taking all of her emotional strength to push it back down.

"All these people on Earth, in the universe, died, and for what?" Homelander continued. "We can't bring them back. Thanos destroyed the stones."

At this point, Maeve could barely hear men and women sobbing, most likely from just losing their loved ones, and they would never get to see them again.

"But… I assure you… the Seven will always be here." Homelander began to wrap up his speech. "The Avengers failed to save the world. We won't."

In the months that followed, incidents began popping up around the country. Crime had skyrocketed after the Snap, with even more supes being revealed across the nation. The heroes hailing from what was once called Earth One appeared more frequently, and then suddenly died off. Superman and Supergirl were found with kryptonite spikes through their hearts, and although Lex Luthor was accused, it was never confirmed. Batwoman was found with a gaping hole in her chest, and her skull split in two. The Flash and Vibe had vanished into obscurity, until they was no more than a washed up celebrities. Their allies were found dead in an alley, having been incinerated. Some people questioned if it was the Lamplighter, but those voices that spoke out were quickly silenced. The Legends of Tomorrow, as they called themselves, were apparently caught in a dirty bomb, with their time machine space ship being destroyed to boot. Black Lightning was found with a single bullet to the head, the result of one lucky criminal getting the drop. And the Seven… they rose to popularity.

But that wasn't without their own challenges. Having been relatively new to saving the world, they would often make mistakes. A building needlessly destroyed here, some civilians killed in the crossfire there, nothing big really. Vought would usually shoo questions away, saying there is always collateral damage when saving a city or the world. That was, until the CIA came knocking on their door, led by a woman named Grace Mallory. She had evidence against the Seven, or more specifically, one of their members...

"I DIDN'T FUCKING DO IT!" Jack From Jupiter screamed at the top of his lungs. Behind him, in the Seven's office on the gigantic flat screen television, was a video of his red, naked body, apparently having sexual intercourse with transsexuals.

"I'M FUCKING INNOCENT, I SWEAR!"

"Regardless, you're done." Homelander said, matter of factly.

"What?" Jack's eyes widened to the size of saucers.

"The video shows you killing one of them." A-Train pointed out.

"SHUT THE FUCK UP, R-TARD!" Jack yelled again. "I DIDN'T KILL THAT TRANNY! I DIDN'T! IF I GO DOWN, YOU'RE ALL GOING DOWN WITH ME!"

"And what will you do?" Homelander asked, curious.

"Careful, remember what happened to Mister Marathon-" Queen Maeve warned, but quickly went silent, when Homelander shot her a glare.

"Like you give a fuck, Wonder Tits!" Jack yelled. "So what, I'll be exiled like that nigger from Teenage Kix?"

A-Train tensed, remembering when his old friend Shout Out was kicked from the team.

"Watch your mouth." the Deep warned, folding his arms over his chest.

"Ooh, scary!" Jack taunted. "Now I'm getting shit from the least black black man on the planet!"

"The fuck are you talking about?" the Deep asked, narrowing his eyes and curling his hands into fists.

"I mean to try speaking in ebonics." Jack sneered. "Try sounding a bit more ghetto, you jiggaboo."

The Deep barely made a sound, as his fist backhanded into Jupiter, crashing into his jaw and causing an audible cracking sound throughout the room.

"That's enough." Homelander declared, grabbing the Deep's arm and staring at the both of them with anger. Jack gulped, seeing his eyes glow crimson.

"Look, I'm sorry man." Jack stammered. "It's just… this isn't just about me. It's about you. It's about the Seven."

Jack began sobbing, as tears streamed down his face.

"You can listen to my heartbeat if you want, but I think you know I'm telling the truth." Jack sniffed out. "I didn't kill the tranny, I swear. But is it this easy? For them to just fake a video, and boom, one of the top supes alive is taken down? You can't let this stand, Homelander."

"I'm not." Homelander's lips curled into a smirk. "Vought is photoshopping your face out as we speak. Meanwhile, I sent Lamplighter on an… errand."

A-Train and Maeve looked around, only now realizing that their teammate wasn't around. Translucent wasn't either, but he was most likely in the corner, being invisible.

The following morning, it was revealed that Mallory's grandchildren were burned alive, in front of her eyes. Though she claimed it was an arsonist who attacked them, Vought and the Seven knew the truth, and they had no choice but to force Lamplighter out as well, for fear of retaliation. Nevertheless, Mallory and the CIA quit investigating them, and the supes only got worse with their recklessness and endangering lives.

Replacing Jack From Jupiter was easy, as Vought already had a candidate lined up. The team was shocked, when their bosses, the married couple James and Madelyn Stillwell, unveiled a man wearing all black armor, named Black Noir. He was silent, his face was completely covered in a mask, and he was a deadly assassin. Vought explained he could be sent out to take care of black ops missions that even the Seven wouldn't get involved in, but his identity was a complete mystery. Homelander once tried to use his x-ray vision to see through the mask, but found the material was lined with zinc, the one substance he could not see through.

Though Jack was easily replaced, Lamplighter took time. Days turned into weeks. Weeks turned into months. Months began to extend out to a few years. However many interviews were conducted, none of the supes could hold a candle to Lamplighter, which disappointed Vought. At this point, they were on the verge of giving up, and began to consider renaming the team to the Six, at least until they could add one more person.

A/N: So a couple things have to be explained, I think.

First off, if Homelander got into an actual fight with Thor or Superman, he would lose, very badly. However, he is extremely lazy with saving people, especially in the show, and just resorts to using his laser eyes to solve every problem. That's the only reason he killed all the Avengers. Same goes for Thanos, if he actually felt like fighting, Homelander would've been wiped out.

Some characters mentioned, like Lex Luthor and Jack from Jupiter, might show up in future chapters. At the time this note got written, I finished writing the chapter that corresponds with season 2 episode 3, and the teaser I ended it on is way different than what the actual episode ended with. Just a forewarning to when I eventually upload it.

Speaking of Jack from Jupiter, I don't want to hear anyone saying they were offended by what he said. A lot of his dialogue is lifted straight from the panels of the actual comic. Oh, and the Deep's race is changed back to black in this story. A-Train is kept his show race though.

Anyway, the next chapter will pick up where season 1 starts. There might be some scenes that feel rushed, or completely skipped over, but like I said, I felt like they didn't contribute much to the story I'm trying to tell.
