Villains that permanently went legit?

[Triniking1234]

For the Black Knight one, I think the only times he was ever villainous it was due to manipulation from others.

Problem with the face turns for Juggernaut..he has to be powered down.

The X writers really just need to decide what lane Juggernaut is riding in and stick to it. The flip flopping is really watering the character down.

[MyriVerse]

What are the former villains that went legit and became good guys, never to return again (apart from maybe an instance or two of backsliding by a bad writer)?

Just off the top of my head:

• Hawkeye
• Quicksilver
• Scarlet Witch
• Black Widow
• Black Knight
• Wonder Man
• Rogue
• Venom
• Screaming Mimi (now known as Songbird)
• Beetle (now known as MACH)
• Emma Frost

Honorable Mention

• Sandman (went legit throughout the '80s and '90s, and was even an Avenger, but eventually went back to villainy)

Anyone else to note?

Also, we can include honorable mentions for villains who had a long streak of being good, before permanently going back to villainy, just as an extra note.

Scratch Emma off that list. She went back to villainy when she dumped Cyclops.

[MyriVerse]

Yeah, that happened in X-Men Blue, so blame Bunn.

Emma went back to the Hellfire Club when she dumped Scott just before Secret Wars.

Emma went back to the Hellfire Club when she dumped Scott just before Secret Wars.

this is news to me.

[Captain Craig]

Looking over the comments so far the only addition I think I have is: Molten Man

Regarding Black Knight(Dane), he was only a "villain" in the same way one would call Green Hornet a villain.
If you're unfamiliar GH poses as a mob boss to compete but is really getting intel.

[CoCoBandz]

We're gonna be able to add Poccy to that list pretty soon.
