You say Zoro can slice Wolverine's head off which is just mathematically impossible, I don't even know what to tell you other than you're basically arguing 2+2=5, anyone who knows the first thing about both verses would never make such a ridiculous claim. Allow me to educate you:
Here's Wolverine tanking hits from Namor the Submariner, who has never been calced below Large Planet level and has been calced as high as solar system level:
Here's f***ing World War Hulk stating he can't Kill Wolverine:
Here's Wolverine getting punched into orbit and taking no skeletal damage:
Here's Wolverine surviving Hiroshima
Here's my personal favorite, Wolverine straight up getting clocked in the mouth by Thor's Mjolnir and them
immediately injuring Thor right afterward:
Speaking of Thor, here's a version of Wolverine
without his healing factor, tanking a hit from Thor and receiving 0 skeletal damage:
Surely I don't have to tell you how retardedly strong Thor with Mjolnir is, Solar System at minimum.
So yeah, I question whether you've even read any Wolverine comics when you make the claims you've made in this thread.
