How have they handled him in recent comics? I know he's appeared off and on in the last couple decades, and I would like to think they found away to move past the old racists stereotype.It's not like a Chinese person can't learn karate.
Not the point. The point is that the character was an ill-conceived generically Oriental villain, just one big heaping pile of ignorant Yellow-Peril stereotypes. I love the way IM3 took that unfortunate legacy and deconstructed it, making that hodgepodge of cultural stereotypes and fearmongering the smokescreen that a white American constructed in order to play on white Americans' fears and ignorance. Rather than trying to ignore the problematic aspects of the character, the film engaged with them metatextually and used them in a smart and self-aware way. I feel that any attempt to revisit the idea of a "real" Mandarin in a more conventional, unironic way would be a step down from that in intelligence, and would be kind of hypocritical.
The first and quite possibly only Mandarin story I read was from the very early '90s and had Fin Fang Foom in it. I don't recall any racist stereotyping in it and in the end the Mandarin had lost his memory and was turned into a mere peasant working the land. I thought it was a pretty story and it had Stark and the Mandarin working together to beat the dragon.
