Sabretooth vs beast
I would think Sabretooth wins because. Sabretooth has adamantium claws that can pretty much cut through anything and he has a adamantium skeleton and a healing factor. He is immune to Cold snap and Frostbite. Beast on the other hand have some similarities to Sabretooth. His blue fur allows him to resist bleeding although beast is physically stronger. With the adamantium claws on Sabretooth‘s side Im pretty sure he can take down Beast.
