X-Men: Evolution: Grim Reminder

Wolverine's tortured origin comes back to haunt him. He goes into the Canadian wilderness to find Weapon X. He runs into not only his archrival Sabretooth, but the doctor who gave him his adamantium skeleton. It turns out that the doctor still plans to use Wolverine to carry out Weapon X by brainwashing him with a microchip that was implanted into Logan's brain a long time ago. It's up to Shadowcat and Nightcrawler (who accompanied Wolverine accidentally, as they were in the X-Jet when he took it) to save the day.
