Somewhere in the multiverse.

Fu was bored.

He was done studying Ultra Ego Vegeta and Freiza Black.

He found a universe where Nappa and Radiz have Super Sayin forms.

So he decided to get some manga and american graphic novels.

Fu: "Hmmm, these universes seem pretty cool."

"It would be cool to have some death battles between the characters."

So he decided to get some heroes and villains from the different universes and have a epic adventure and battle.

In the DC universe.

The Justice league was fighting granny goodness?

Superman: "You are really using Darkside's henchmen to defeat us?"

Granny: "SHUT UP I WILL DEFEAT Y'ALL!"

"Ugh."

Booster gold has punched her in stomach knocking her out.

Booster Gold: "HA!" "An easy win!"

Suddenly, their hands start to fade away.

Green Lantern: "What is happening?!"

Wonder Woman: "I don't know!"

They then disperse.

They end up in some kind of city unknown to them.

Wonder Woman: "Where are we?"

Shazam looks at a signs that says West City.

Then all the sudden, five other fighters have appeared.

Green guy: "What the-?!"

"Who the hell are you all!?"

Superman: "Well, we are-"

He was interrupted by Fu who teleported to meet them.

Fu: "Well, hello heroes, how are y'all today?

Trunks: "FU!"

Trunks fly's up to attack him, but gets grabbed by his henchmen.

Fu: "Ah Trunks, you have met my henchmen."

"Meet, Cyber Tao, Dr Gero, Baby Vegeta, Turles, and DBZ Broly!"

Trunks: "What? Why are they following your orders!?"

Fu: "See their foreheads? The F on them, that means they are under my control."

He said with a smug face.

Fu: "Well I will let y'all meet each other and I will give y'all instructions later."

"BYE!"

Green guy: "So who where y'all again?"

Superman: "We are the justus league."
