Dragon Ball X DC Comics.

Cell

So this is the Justice League's universe...

Cell

Perfect. I mean, with the Joker dead and these pathetic villains dealt with...

Batman

You're not from around here, are you?

Batman

Another interdimensional threat. Great.

Superman

Whatever you're planning, it ends here.

Superman

We protect this world from threats like you.

Wonder Woman

The Amazons have faced creatures like you before.

Wonder Woman

You underestimate Earth's heroes at your own peril.

Son Goku

Hey! You must be Cell from another timeline!

Son Goku

This is gonna be fun! Right, Vegeta?

Vegeta

Kakarot, you fool! This isn't a game!

Vegeta

Cell! I'll show you what a true Saiyan Prince can do!

Cell

How delightful! Both timelines converging...

Cell

Now I can test my perfection against BOTH universes' greatest warriors!

Batman

Alfred, contact the rest of the League. Code Red.

Batman

And maybe start praying to whatever gods are listening...
