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).This ability is so powerful that in the event that Logan's heart has been ripped out or if he has suffered brain death then his Healing factor will bring him back,resurrecting him so to speak.
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.
- Martial Arts:Logan has lived for centuries and due to his time in the military and some training he has received in Japan,Logan is an expert martial artist and unarmed fighter he has been trained in Karate,Judo,Boxing and many others.
- Weapons master:As previously mentioned Wolverine is an expert fighter due to living for two centuries,he has mastered numerous weapons with deadly accuracy including firearms, and blades and even grenades.Logan can use almost any weapon.
- Linguist:Logan can speak multiple languages other than English this list includes French,Japanese,Russian,Vietnamese,Spainish,Chinese and even Thai.
- Decapitation:Wolverine's body can regenerate any damage unless his head is separated from the rest of his body.Charles Xavier explains this is due to the fact that Logan's healing factor works by his brain sending signals to the rest of body and that if someone can destroy the connection between his brain and the rest of his body then he would die however the Adamantium skeleton makes it almost impossible to do so
- Drowning:While Wolverine can heal physical damage,Drowning him would be lethal as it would kill his lung cells and even if generated new cells they would die off.It doesn't help that Wolverine's skeleton weighes him and that he can't swim.
- Berserker rage:According to the information Weapon X has on Wolverine,he was programmed to be an animalistic killing machine and due to his short temper they were able to program him with a berserker rage where he ignores all pain and unleashes deadly animalistic almost savage rage upon whatever triggered the Berserker rage.
- Draining his Healing Factor:It is possible to drain Wolverine's Healing factor,If he starves,is infected with a specific virus or even some magic or matter manipulation can shut off Wolverine's Healing factor making him vulnerable to any injury and as easy to kill as an regular human.
