Elon Musk is still somewhere between Harvey Dent and Two-Face. He was a big shot genius playboy until he got jealous of a diver who saved some kids he was trying to save. This percieved slight lead to his long, slow slide into madness signalled by launching cars into space and mass producing consumer-grade flamethrowers.
Trump is the obvious candidate. Degenerate billionaire and confirmed sexual predator gets elected president by calling ignorant nationalists to his banner with false promises and appealing to their biases. Once he gets elected he spends his time feverishly trying to hold onto his power by undermining everyone around him and torturing already persecuted minority groups. It's like Dark Reign if the Green Goblin was orange and Osborn was retarded.
Putin is just a generic Punisher Villian.
