I've noticed something everybody. So far the X-Men have had 4 cartoon series but as the years have gone on each series has been getting shorter.
X-Men the Animated series (1992-1997)- 76 episodes.
X-Men Evolution (2000-2003)- 52 episodes
Wolverine and the X-Men (2009)- 26 episodes
X-Men Anime (2011)- 12 episodes
