A mysterious enemy from Wolverine’s past Sabretooth would battle Wolverine at any given opportunity. Logan hates Sabertooth due to their history in Weapon X. Sabretooth is apparently an ally of the man who created Wolverine’s adamantium skeleton.
Powers and AbilitiesEdit
Regenerative Healing Factor: Sabretooth's primary mutant power was an accelerated healing process that enabled him to regenerate damaged or destroyed areas of his anatomy with far greater efficiency than an ordinary human. Originally, the speed of Sabretooth's healing factor's was in proportion to the wound's severity; for example, he could fully recover from an ordinary gunshot wound within minutes or injuries as severe as a broken back and severed spine within days. However, Sabretooth's healing ability was dramatically increased in recent years due to various augmentation procedures. Sabretooth could fully heal from injuries that result in massive tissue damage or loss such as multiple gunshot wounds, slashes, puncture wounds, blunt force trauma, and severe burns within a matter of moments.
- Foreign Chemical Immunity: Sabretooth's natural healing also afforded him the virtual immunity to poisons and most drugs. It was virtually impossible for him to become intoxicated.
- Immunity To Diseases: Sabretooth's healing powers also extended to his highly efficient immune system. As a result, he was immune to the effects of all known Earthly diseases and infections.
- Weather Insulated Adaptation: Sabretooth was able to withstand incredibly cold temperatures without sustaining bodily damage for great periods of time, even to the point of being nude in sub-zero temperatures.
- Extended Longevity: In addition, Sabretooth's healing factor provided him with an extended lifespan by slowing the effects of the aging process. He has claimed to be even older than Wolverine. Despite being of an, unknown, advanced age, Sabretooth retained the appearance and vitality of a man in his physical prime when he was killed by Wolverine.
- Superhuman Stamina: Sabretooth's advanced musculature produced considerably less fatigue toxins during physical activity than an ordinary human, due in large part to the effects of his mutant healing factor. Before receiving various upgrades to his powers, Sabretooth could physically exert himself at peak capacity for several hours before the build up of fatigue toxins began to impair him. After the upgrades, his stamina was increased to the point where he could exert himself at peak capacity for at least 24 hours.
Superhuman Strength: Sabretooth possessed superhuman strength that has been artificially augmented on a number of occasions over the years. Initially, he possessed sufficient strength to lift slightly above 800 lbs for brief amounts of time  , slightly greater than the maximum amount an ordinary human is capable of lifting. However, after being captured and augmented the first time by his son, Graydon Creed, his strength was increased to the point where he could lift about 2 tons. He also underwent various augmentation procedures at the hands of the latest incarnation of the Weapon X Program, including some to both his strength and healing factor. While the full limits of his strength weren't revealed, the latest Wolverine handbook confirms sabretooth being stronger than Wolverine who is stated to be able to lift in excess of 800 lbs for brief periods 
Superhuman Agility: Sabretooth's agility, balance, and bodily coordination were enhanced to levels beyond the human body's natural limits, even those of the finest human athlete.
Superhuman Reflexes: Sabretooth's reflexes wase similarly enhanced and were superior to those of the finest human athlete.
Superhumanly Acute Senses: Sabretooth's feral mutation provided him superhumanly acute senses. Sabretooth could see with greater clarity and greater distances than an ordinary human. His vision extended into the ultraviolet and infrared areas of the electromagnetic spectrum, allowing him to see in near-total darkness and retain the same level of clarity. Sabretooth's hearing was similarly enhanced, able to detect sounds that ordinary human's can't and at greater distances. For example, he could detect the sound of light, normal breathing within a distance of 200 feet. Sabretooth also possessed an extremely well developed sense of smell. Sabretooth could recognize or track targets by scent, much the same way as a dog or wolf does. His nose could detect minute chemical differences in the scents of different deodorant brands, even if they were purported to be exactly the same scent.
Claws and Fangs:' Sabretooth has large canine teeth, akin to a big cat which are much larger than a normal human's canine teeth. Most of his teeth are large and sharper than a normal human's, but it is his pronounced upper and lower canines from which he gets his name that are truly animal teeth. He also has retractable talons in place of fingernails. The claws are naturally sharp and tougher than that of normal human bone structure, allowing Sabretooth to cut through most types of flesh and natural materials. Sabretooth's ability to slice completely through a substance depends on the thickness of the substance and the amount of force he can exert. At times, Sabretooth's claws, along with his skeleton, have been bonded with Adamantium. As a result, his claws were virtually indestructible. The Adamantium further enhanced the already razor sharp edge of Sabretooth's claws and enabled him to slice through almost any surface, with the known exceptions of Adamantium itself and Captain America's shield.
Psionic Resistance:' For a time Sabertooth had trouble with psionic altercations, but became immune to telepathic manipulation after an incident when Wolverine punctured his frontal lobe.this was made evident when Elizabeth Braddock stabbed him in the head with her Psionic katana.
Sabretooth is an excellent hand to hand combatant, having been trained by various organizations such as the CIA, Weapon X, the Foreigner, and HYDRA. He is also an expert hunter and tracker, even without the use of his heightened senses. Sabretooth also has developed a high resistance to telepathic probing and manipulation. Although his extreme arrogance gives him the appearance of stupidity, he is actually quite intelligent. He routinely hacks into government databases to steal classified information and has escaped the highest levels of incarceration. He also has a pronounced assault leap, which few can sense, even those like wolverine who have animal senses. This leap is a combination of his superhuman strength, reflex and agility working in concert, flexing and un-flexing his muscles much harder and quicker than a normal human, similar to a tiger or lion's pounce. This allows for a devastatingly powerful and fast leap onto the opponent, which few can recover from.
Special Skills: Due to his extensive training Sabretooth was an exceptional hand-to-hand combatant. He was also a trained expert in multiple types of weapons, vehicles, explosives, and assassination techniques.
Class 10 . Able to lift in 2 - 10 ton range , however the extent of his continuously enchanced strength was never revealed.
Sabretooth was vulnerable to the Muramasa Blade. The sword, which was constructed through some means with the use of a piece of Wolverine's own soul, had the ability to greatly nullify the efficiency of an accelerated healing factor.
