Spyke from the TV show is a young, Black mutant who has the powers of Marrow and was most likely added to the cast to add some minority flavor to the TV show.
The girl who I said I didn't know the name of in the movie was Callisto... but they also modifies her powers for the movie.
Spike was first introduced in X-Force 120, in December 2001. He is based on Spyke who was introduced a year earlier in X-Men: Evolution in November/December 2000.
...so your assumption isn't entirely wrong regarding Spike being based upon the X-Men: Evolution character, as both the comic book and movie interpretations are obvioulsy based on him.
