10 Times Comic Book Villains Became Heroes (In A Big Way)

Deadpool, Magneto, Riddler and Harley Quinn are just some of the villains who became heroes.

The vast majority of comic book villains tend to stay on the path of evil, but a select number have switched allegiances to the side of right over the years.

Whether in the Marvel or DC universes, creators have been reforming and redeeming plenty of major supervillains for decades now, and though most don't manage to make the switch permanent (curse you, superhero status-quo), that doesn't make the novelty of seeing them fight alongside their old rivals any less entertaining.

Some of the most beloved and famous heroes in both the Big Two's libraries originally had villainous roots, but a lot of the time these characters' paths towards redemption were mapped out very early on or even right from the off - such was the case with Rogue, Plastic Man and Hawkeye, to name but a few.

All those characters are great, of course, but the brief time they all spent as villains has been well and truly eclipsed by their heroic personas.

That isn't the case for some of the other notable supervillain defectors though. These characters had to wait decades to switch allegiances - however brief a switch it was - but they all managed to do so in massive and oftentimes immensely gratifying ways, leaving readers desperate to see them become heroes for good.

10. Songbird

Songbird was originally introduced as the supervillain known as Screaming Mimi (okay.... I love the name) by Mark Gruenwald, Ralph Macchio and John Byrne in 1979's Marvel Two-in-One #54, before later switching to the Songbird identity in the 1990s.

Originally an antagonist who was a member of the evil wrestling-themed supervillain team known as the Grapplers, Screaming Mimi was subjected to a process by the Power Broker that enhanced her vocal chords, thus giving her the ability to project a deafening supersonic scream not unlike the one belonging to DC's Black Canary, albeit with a few other added perks.

Following her time with the Grapplers, Mimi rejected her old wrestling title and became known as Songbird, eventually linking up with Baron Helmut Zemo and joining his faux superhero team known as the Thunderbolts.

Unfortunately for Zemo, who had planned the Thunderbolts to be nothing more than a trojan horse for the Masters of Evil to exploit, Songbird and many of the other villains recruited for the team actually grew to love playing the hero. She and her teammates betrayed Zemo, and ultimately went on to lead the Thunderbolts in its later incarnations.

Content Producer/Presenter

WhatCulture's very own resident movie guy, Ewan has been working in the content creation biz for over 10 years now, having started as a freelance contributor to WhatCulture Gaming all the way back in 2015. After graduating with a First-Class Honours in History from Northumbria University in 2017 (where he won a prize for a totally killer dissertation on the Watergate years), Ewan took on the role of Comics Editor at WhatCulture and quickly developed WhatCulture Comics into one of the biggest superhero-focused channels on YouTube. He followed this with a brief hiatus at Screen Rant in 2021, where he worked across the Gaming and Film sections as a writer and editor, before returning to WhatCulture as a Senior Content Producer / Presenter in 2023. He started his own podcast, We Love Dad Movies, in 2022, and has contributed several written pieces to the Eisner-nominated comics website Shelfdust as well. In his current role, Ewan incorporates his love of cinema, comic books, and history into written pieces and video essays for WhatCulture's Film & TV channel, as well as WhatCulture Gaming and WhatCulture Horror, with a particular focus on nineties-era Dad Movies, old school Westerns, and Golden Age Hollywood Noir. John Carpenter is his fave, and he thinks Batman Beyond should never have been cancelled. If that's your vibe, you'll probably like his stuff.
