A source close to production has informed Animation Insider that fan-favorite series, X-Men: Evolution has been cancelled. The source then goes on to say that he is unclear whether or not it was a decision by Kids' WB!, the network that has broadcast the hit-series for four seasons, or Marvel Entertainment, the company that produces it.
The series featured teenage versions of the popular X-Men comic-book characters, originally co-created by comic legend, Stan Lee. The series initally focused on the exploits of the characters in high school and the balancing act that came with being both students and mutants. Eventually, the series began to "evolve" and took a more darker and more adult tone in the later seasons. The fifth season, according to our source, would have focused on the Phoenix Saga.
X-Men: Evolution was a ratings hit for Kids' WB! in its four years on the air and gained some critical praise from people of all ages."
