Random Superheroes Who Started Out As Villains (22 items)

(#1) Sam Wilson (Falcon)
Not only is Falcon Captain America's best friend (next to Bucky), he spent a spell wearing the red, white, and blue as Cap. But he actually got his powers working alongside Red Skull. Before he turned good he was a petty Harlem thug and Red Skull henchman, then on getting his powers quickly turned on Skull and teamed up with Cap. They've been bros ever since.
(#5) Gambit
Gambit is one of those heroes that always seems to be up to something. That's because he started as a villain, albeit a charming man-about-town thief of a villain. It was later revealed he was partially responsible for the massacre of the Morlocks. He's made up for as a member of Xavier's crew, though.
(#22) Pied Piper
Not only is Pied Piper a reformed supervillain (since Barry Allen's death Hartley has been on the up and up) he's also one of DC's first openly gay characters. He used to be one of Flash's consistent bad guys, but now he's more of a robin hood type figure.
(#20) Shade
Shade began as a multi-generational villain. He fought against Flash in both the GOlden and Silver ages. He eventually evolved into a mentor for Starman and more of a morally ambiguous anti-hero than full-on bad guy.
(#17) Bombshell
She's a tricky one to pin down. She began as a member of the Teen Titans, and then in issue #40, she was revealed as a traitor. After being kicked off the team, she reformed and often teams up with Batgirl. So she's a villain disguised as a hero who turned into a real hero.
(#6) Venom
Venom started as a villain specifically out to get Spider-Man. Eddie Brock knew all Spidey's secrets, had all his abilities, and firmly believed that Peter Parker was responsible for everything that had gone wrong in his life. Eventually, he came to see that Spidey was just trying to make the world better, and he even fought alongside his former enemy. Nowadays venom is on Flash Thompson and is a full fledged government issued hero.
