Healing Factor:Wolverine's mutant power is his healing factor,he can regenerate all manner of wounds from being impaled,shot and burnt to having his eyes gouged out and being reduced an Adamantium skeleton,As a result he can regenerate limbs and organs,Wolverine's healing factor also seems to slow or maybe even halt(or maybe even Cease)his Aging process as he is over 200 years old yet still retains the appearance of a man in his 20s or 30s.He also has healed from the Ebola virus and Malaria within the same week which means he is immune to most Earthly diseases and can't get drunk or be high on drugs(though he still has a habit to do both).
Enhanced senses:Wolverine has keen senses of smell,touch,taste,hearing and sight,these are better than most humans and even animals like dogs.Wolverine's sense of smell means he can't be sneaken up upon or be attacked from behind
Enhanced strength:Due to a combination of military training,working in the mines for a few years,his Adamantium skeleton and his healing factor Wolverine is stronger than an average human being he can lift up to 2 tons at peak,he has crushed a pure steel Pipe in his hands,Snapped Dinosaur's neck and even kicked a boulder.
Enhanced speed/Agility:Wolverine can move faster than the eye can see and is an excellent acrobat he also has acrobatic skill from his time in Weapon X.He can dodge boulders thrown at him by the Hulk and leap at Satan and even tag Speed Demon who moves faster than sound.
Retractable Adamantium Claws and Adamantium Skeleton:Wolverine was born with six 12 inch blades on both of his hands,these pop out of his knuckles whenever he wants them to,Originally these were bone claws but when Weapon X experimented on him he has his claws and his whole skeleton coated in Adamantium,the strongest substance known to man,Wolverine's claws are so sharp that they can cut through beings like The Hulk and Jackie Estacado,himself.Wolverine's Adamantium can survive nukes and even blows from the Hulk and Thor.
