I don't think there has been a Bizarro thread yet, so I took the liberty to make one.

If they want a Superman villian, even though Lex is more iconic, Bizarro would be a much better choice for many reasons.

He's a colorful character, it would be fun to play as him.

At the end of the round, if Bizarro wins, it could say "Begin Him!" and "Bizarro Loses!". That would be awesome.

His moveset would be the opposite of Supermans.

Arctic Vision that freezes opponent. Originally Heat Vision

Flame Breath that sets on fire (Like Scorpions hellfire move) Originally Freeze Breath

Super Breath to blow his opponent onto the ground, he then jumps and stomps on them. Originally Vacuum Breath

Pound Uppercut - Does a super strong uppercut to opponent that pops them up in the air. Originally Ground Pound

Fatality: Throw opponent high up in the air, they are up there for a long time, they eventually fall and die.
