10 Best X-Men: The Animated Series Episodes
9. The Cure
The first season of X-Men rolled out major villains at a fast clip, with Magneto, Sabretooth, Juggernaut, Sentinels, and Master Mold introduced in the first few episodes. Instead of gradually warming the X-Men up to mega-threats with low-level goons like Toad or Blob, this introduction to the big-bads early on made it clear that any villain could appear at any time.
The Cure started of by casually walking Mystique, Pyro, and Avalanche into the picture then, boom! They dropped Apocalypse on us.
Keep in mind, the series isn't even into double-digit episodes yet. To bring in one of the most dangerous entities in X-Men lore within the first few chapters of the story was a huge move. With such a monumental character now present, fans had no idea where the series would go, which made looking forward to the next episode all the more exciting.
