Vampire Wolverine vs Hulk
From the "what IF' comic wolverine gets bitten by a vamp and is turned into one. All his powers are amplified over 10x over basically made him extremly ruthless and vile..He looked pretty cool to boot...he can fly too but didnt hardly any. He killed dracula after being bit and killed all the other xmen. I cant remember if The Punisher killed him or something...i dunno...weird plot.
IMO this is the only version of Wolvie who has a chance at killing hulk
