[Jason Abbadon]

Hmmm...for heroes, I'd probably go with...um...Geez..Gladiator? He's got insane powers and he' got no problem killing a bitch to get his point across.
He's gone far beyond the Superman allegory he started out as.
I'd also love to be Quasar- Protector Of The Universe and Avatar of Infinity! Bearer of the Quantum Bands and Cosmic Awareness! Avenger! Unkillable (for long anyway), he always fights the good fight.

For Villians..possibly Malestrom or Count Nefaria.
malestrom is so impossibly powerful and ballsy that he trash-talked thanos- when thanos had the Infinity Gauntlet! And got away with it! He's Thanos' alternate as avatar for death/Oblivion.
Count Nefaria beacuse he's impossibly tough- laughing off the ENTIRE Avengers and Thunderbolts teams at the same time! He een laughed off Thor's hammer to the face!
The face!
