Sabretooth

Sabretooth is Wolverine's sworn arch-enemy.

Ultimate Spider-Man
Sabretooth went to Logan's apartment to kill him, not knowing that he had switched bodies with Spider-Man. When Peter arrived at school followed by Sabretooth, he told Wolverine to put on his Spider-Man costume. Wolverine objected at first, but, but did so eventually. Together, Wolverine and Spider-Man fought Sabretooth and defeated him.
