Brainiac, the Evil Villain Alliance, and Black Death Emperor Wants to Be the Leader

I was Brainiac.

I was originally Brainiac, appointed by Colu. I crossed the cosmos solely to gather all the knowledge in the universe.

I should have invaded some parallel universe's Earth in an ordinary manner, like the countless Brainiacs born since the multiverse came into existence, attempting to collect a city in my bottle before being defeated by Superman, Batman, or even the entire Justice League, ultimately bringing my ridiculous life to an end.

To the entire multiverse, the role and meaning I played was to become a "trial" for the superheroes. To fight true threats, the superheroes—the multiverse's "immune system"—had to maintain powerful combat abilities.

It was a magnificent sight beyond the
