10 Comic Heroes Who Killed Their Biggest Rival
2. Wolverine Kills Sabretooth - Wolverine (Vol. 3) #55
As a practically unkillable murder machine, it seemed sure that Wolverine would never get to kill Sabretooth in the main Marvel universe.
These doubts were safely assuaged in Wolverine #55, where Logan would find the villain practically feral in the Canadian wilderness. Armed with the Muramasa blade - one of the few things capable of blocking Creed's healing factor - the hero gets to work putting the mad beast down, starting by chopping his arms off, and then finishing with a suitably gory beheading.
Although it would later be revealed that this was merely one of countless clones that Romulus had made to stand in for the actual Victor Creed, it does still count as Wolverine killing Sabretooth - just not the Sabretooth you maybe wanted him to kill.
