6. Nighthawk
(Squadron Supreme, Marvel Comics)
Kyle Richmond, aka Nighthawk, was a founding member of the Squadron Supreme, Marvel’s analogues to the Justice League. Nighthawk served as the team’s Batman, unpowered but highly trained and skilled. The Avengers traveled to the Squadron’s dimension to help them overpower an evil cabal controlling the President. In the aftermath, Richmond decided to retire from his heroing to help the nation recover as a political official.
He eventually won the presidency and started making headway. Unfortunately, he was then mind controlled himself, by an evil alien intelligence, until the Defenders showed up and saved him. Lotta mind-controlling of Presidents in this universe. After the Defenders left, Hyperion and the Squadron Supreme decided to use their power to fix the world as they saw fit. President Nighthawk did not like this plan and quit the Squadron, vowing to do everything in his power to stop his former friends.
Nighthawk eventually won the battle based on ideology, but that’s not the point. The point is that, as much as I like Nighthawk, spending half your presidency mind controlled and then doing battle with all your former friends as they try to bend the world to their will isn’t the BESTEST track record.
