I'm a mutant who possesses the ability to regenerate damaged or destroyed areas of my cellular structure at a rate far greater than that of an ordinary human. The speed at which my healing factor works varies in direct proportion with the severity of the damage that I suffer. For example, I can fully recover from an ordinary gunshot wound in a non-vital area of my body within minutes, but it took me almost two months to fully recover from injuries sustained in a duel with Lord Shingen, which included one from a sword that went all the way through my trunk.
My natural healing also affords me virtual immunity to poisons and most drugs, as well as an enhanced resistance to diseases. For example, it is nearly impossible for me to become intoxicated from drinking alcohol. I also have a limited immunity to the fatigue poisons generated by bodily activity, and hence I have greater endurance than an ordinary human. My agility and reflexes are similarly enhanced.
In addition, my healing factor provides me with an extended lifespan by slowing the effects of the aging process. Although over a century old, I'm as healthy and physically fit as a man in his prime.
I also possess superhumanly acute senses, making me capable of seeing things at a maximum distance greater than a normal human. My hearing is enhanced in a similar manner, and I'm able to recognize people and objects by scent, even if that person or object is hidden. I also can use these enhanced senses to track any creature with an impressive degree of success.
My skeleton includes six retractable one-foot long bone claws, three in each arm, that are housed beneath the skin and muscle of my forearms. I can, at will, release these slightly curved claws through the skin beneath my knuckles on each hand. The skin between my knuckles tears and bleeds, but the blood loss is quickly halted by my healing factor. I can unsheathe any number of my claws at once, although I must keep my wrists straight at the moment my claws shoot from my forearms into my hands. When unsheathed, my claws are fully within my hands, and thus I can still bend my wrists. My claws are naturally sharp and tougher than that of normal human bone structure, allowing me to cut through most types of flesh and natural materials.
My entire skeletal structure, including my claws, have been artificially bonded to the nearly indestructible metal Adamantium. As a result, my bones are virtually unbreakable, and my claws are capable of cutting through almost any substance depending on its thickness and the amount of force I can exert. Due to my healing factor, the presence of Adamantium in my body does not interfere with my bones’ normal function of generating blood corpuscles. The reinforcement of my skeleton enables me to withstand high levels of physical pressure, giving my muscles sufficient force to briefly lift/press several hundred pounds. Throughout my life, I've used a variety of bladed weapons, most frequently daggers and, at times, swords. I also have wielded many different types of firearms throughout my careers as a soldier, a mercenary, and a spy.
Despite the extent of my healing factor, I'm not immortal. If the injuries are extensive enough, especially if they result in the loss of vital organs, large amounts of blood, and/or loss of physical form, such as having flesh burned away by fire or acid, I can die.
Due to my extensive training as a soldier, a C.I.A. operative, a samurai, a spy, and a member of the X-Men, I'm an exceptional hand-to-hand combatant, having mastered virtually every fighting style on Earth. I'm also a trained expert in multiple types of weapons, vehicles, computer systems, explosives, and assassination techniques. I'm the Professor of Art... and to kill a Sentinel is an art form.
