X-Men: Evolution (2000)

S1E5 Speed and Spyke

Ororo's nephew begins to display his mutant abilities, but instead of focusing on his newfound powers, he is more preoccupied with confronting a rival mutant. Dismissing the idea of attending a “school for freaks,” he is determined to prove himself in a personal competition, leading to a clash that tests both his skills and his understanding of his identity.
