This is a style for the Invincible VS game. I didn't include all characters in the dataset, but here are the ones I did include:
Invincible
Atom Eve
Omni-Man
Robot
Rex Splode
DupliKate
Cecil
Allen the Alien
Anissa
Conquest
The tags for them is just their names (aside from Robot, just put "Robot (Invincible)" for him).
