Accept the things you can't change, have the courage to change the things you can, and have the wisdom to know the difference...

The Avengers, X-Men, and the Justice League members all come together to discuss something that has appeared on their solar system.

"Thank you for responding so quickly." Clark Kent thanks the teams for coming together fast. "Some of you already know what this is about, but I wanted to get the new members up to speed." He then pulls up a photo of a planet that looks to be on fire.

"This is Apokolips, home world of Darkseid, a power-mad despot who has orchestrated two attempted invasions of Earth, the first which resulted in the formation of the Justice League. The second one, an attack from within our ranks by Cyborg Superman and his cyber force." Bruce Wayne finishes.

"Yeah, we kinda don't need a reminder of that. It was all over the news." Tony Stark reminds them.

"Nevertheless, this image was taken by surveillance ten hours ago on the edge of the solar system." Bruce finishes explaining.

"Apokolips phases into our dimension and released stealth drones, then phased out again." Diana continues.

"This can only be looked at as a prelude to war. Darkseid aims to conquer the Earth and crush it under his heel." Clark says.

"What villain doesn't want to do that?" Cyclops asks.

"Look, the guy's a regular genocidal maniac, but are we sure he's going to do it, or something he's planning to do?" Barry Allen asks.

Tony then gets up and shows some recent photos that they received from the Guardians.

"These images were taken from the world's That Darkseid has already conquered." Tony says and shows photos of everyone dead and the planet destroyed. "Our intel shows that he's now sent his elite guard and the Furies to act as an occupying force to thwart any resistance."

"I want to make this perfectly clear. We are facing an existential threat to the planet." Clark informs the teams. "We can't wait for Darkseid to make the first move. That could mean the end of us. We have to attack."

"It's gonna be a touch job." Steve Rogers says.

"He's right, that place is gonna be crawling with Parademons." Natasha Romanoff agrees.

"The League's faced them before." Bruce says and shows their weak spots hologram.

"With our combined forces, we can cut through them. Then I'll do what needs to be done." Clark promises the team.

"This is madness." Lex Luther interrupts. "There's always a deal to be made. Let's at least send an envoy to Apokolips."

"No!" Clark says and crushes a table.

"You broke it, it's yours." Tony says, pointing to the table.

"Darkseid created a monster that nearly killed me. What chance would humanity have?" Clark asks. "Our only option is to destroy him."

"That means Earth could be ground zero in a world war. Everyone on the planet would be at risk, everyone we care about." Dr. Strange warns them.

"Hate to admit it, but the magician is right." Constantine agrees with him. "Sure, this guy deserves killing, but you can't kick the hornet's next like everyone on Earth is bulletproof."

"Look, I won't ask you to give anything more than I do. But this isn't up for discussion. We're going to stop Darkseid once and for all." Clark tells them all and start explaining to them the plan.

Unknown to them, the Iron Man mask in the room is acting as a video display for Darkseid.

"Any questions?" Clark asks them all.

"Yeah, like a thousand." Scott Lang says.

"We don't have time for a thousand." Laurel tells him.

"So, were going to space?" Nightcrawler asks.

"Yes, Kurt, were going to space." Jean says.

"We're doing space missions now. Cool." Quicksilver comments.

"Then suit up." Oliver tells everyone as they head to their ships.

The three teams are in their seperate jets and are heading for Apokolips and they opened a portal to get to there faster.

Except when they arrive, they're met with a swarm of stronger Parademons.
