Wolverine VS. Sabretooth
Sabretooth is arguably one of the most tenacious and formidable foes Wolverine has ever faced. Though Sabretooth's claim that he is Wolverine's father is false, there are striking similarities between the two. In their numerous battles, their similarity immediately shows -- these men have never ceased to surpass each other in ferocity and raw savagery. While most of their battles end in a draw, we live in constant fear of a time when there will be a definitive victor -- and an irrevocably dead loser.
