I always wrote it off that she dyed her hair.
J was a white guy in the original comics. K was more of a typical government "spook" that you did not want to mess with. They never showed Zed in the original comic series, either; he was just a voice from an intercom.
Well, J got changed to a black guy (Will Smith) for the first movie. By the end of the movie, J was acting like an old pro, which I didn't care for all that much. But in the animated series, J makes rookie mistakes throughout the entire first season, gradually gaining proficiency. By the end of the first season, he earns a small amount of respect from K but still has a long way to go with his training. (I know that the show continued for several more seasons but I never saw past the first one since that's all that was released -- never saw the show on television, unfortunately.)
Anyways, I really appreciated the changes made for the animated
Men in Black. Season one is far better than the movies, in my opinion.
I've never really been "into" those kinds of comics. But I picked up
Mickey Mouse this year on FCBD, mainly because it had Robin Hood on the cover. I was amazed at how different this Mickey Mouse (by Gottfredson) was! In this, Mickey not only went on adventures, he beat people up, had attitude, and a sense of humor. If Mickey Mouse had been like this when I was growing up, I would have liked him better than Bugs Bunny for sure.
I'm not an expert on the show but I think on
Spider-man: TAS, Hobgoblin was introduced before the Green Goblin, which is backwards from the comics. They made quite a few changes to Marvel Comics continuity -- they totally jacked up Captain America's story as well as
Secret Wars, for example. I could go on but I won't.
X-Men: Evolution changed a lot of the main characters ages. True, the X-Men were just kids when they started but Storm was not one of the teachers, for example. Actually, I think this is a great show despite the changes they made.
In
Mutant League, Bones Jackson from the videogame
Mutant League Football was changed to Bones Justice. Originally, the character's name was satire of the real football/baseball star, Bo Jackson. I do not know if the television show had any legal trouble and had to change the name or not, but they didn't change some of the other names, like Dark Star (ie, Bart Starr, another famous football player); then again, they didn't use other characters at all, like Scary Ice (ie, Jerry Rice) or Coach Bricka (Coach Ditka). Electronic Arts, creators of the videogames and producers of the show, had recently had a legal battle with ESPN over their fictional EASN logo for their sports videogames; the suit was settled out of court and EA changed their sports logo to the now famous EA Sports brand.
Also, Coach McWhimple coached the Sixty-Whiners in the videogame while in the show, he was head coach for the Monsters instead of Coach Bricka. I think they made this change mainly because Bones was the real team leader both on and off the field. McWhimple was too wimpy to give orders to anybody!
