As we all know, there's always been a trend in comics of turning villains good; redemption is a cornerstone of hero comics, dating back to Hawkeye, the Silver Surfer etc. But sometimes, characters just should not turn good.
I love Emma Frost as a character. She's manipulative, she's sexy, she's intelligent. But am I the only one who still finds her being a good guy incredibly forced, 13 years later? I loved The White Queen when I was young because she was incredibly unlikeable and cruel, serving as a foil to the noble X-Women such as Storm. her being a hero still bothers me years later.
So which villain turned hero bothers you the most?
Well I can't agree with you. I like her better as a hero, although i don't really put her as hero. She's doing what she can to help mutants. Frost was never a main villian, she was never behind any major schemes. She was part of the Hellfire club and was a tool for Shaw. He was always the main villian. Frost did show up in some titles doing the solo thing, but she was never as i recall doing terriable things like say Doom, Magneto, Kang, Loki and so forth. I remember her showing up in the New warriors to reclaim Firestar, but that's it. She was an underling and nothing more.
I'm sure you've read Emma's back story and it really does explain her character a lot and give you a better understanding of her. Again even though Emma is with the Xmen she's just not what I consider a hero. Ms Marvel is a hero, Wasp is a hero, Photon is a hero, She hulk is a hero, but Frost is more so doing what she can to help and protect mutants.
Getting technical about it the Xmen themselves has never been what I would call heroes. They do protect Mutant kind and fight for mutants rites, so i can see why they are seen as heroes to some, but teams I call real heroes are The Avengers, JLA, heck even The Authority. These guys do everyday saving of the planet and protecting it for major threats, while the smaller guys like spiderman protect the local public. The Xmen are always fighting other bad mutants who is bent of destroying them or taking something from them, or the Government or mutant hating orginazations. Yeah the Xmen has helped to save the planet at times, but it's been few and far between.
