Another character I like is Doctor Doom. The man took over the world and changed it back because he brainwashed the world, and thought it was a cheap bitter victory. So he gave Magneto his free will just to see if he can reassemble the Avengers to stop him.
Doom goes to hell every year to fight Mephisto for his mother's soul. And he challenge Doctor Strange to become the new Sorceror supreme, and used the contest as a smoke screen to get his mother's soul back from Mephistos, and got it back!
During the whole acts of vengence storyline, everytime doom fights or show up, is a doom bot. How badass is it that you just send look-alike robots to fight for you because you don't feel like it.
He stole the silver surfer, beyonder, tyrax, galactic's power
The man has diplomatic immunity.
He so badass, he put a hot metal mask on his face because Doom doesn't wait.
