15. WOLVERINE AND THE X-MEN (Nicktoons, 2009)
This series started off promising enough: An explosion at the X mansion seemingly takes the life of Professor Xavier and Jean Grey, and the X-Men disband in the aftermath. Years later, the team is forced to reunite in a war-torn dystopia as an epic clash between mutants and humanity looms large.
After just one season, Wolverine And The X-Men vanished from the air without as much as a goodbye, but during its short run the show presented the kind of intricate storytelling and social commentary that X-Men fans are used to. Plus, there was more than enough action to make the 10-year-old in all of us smile with glee.
