Rahne Sinclair - Wolfsbane is a mutant metamorph, allowing her to change her physical form with concentration. Unlike other metamorphs her's is a very specific one better referred to as Lycanthrope, the ability to change to and from a wolf.
She is able, through mental concentration; transform herself into a wolf, while retaining most of her human intelligence, or into a transitional werewolf-like form which combines both human and lupine characteristics.
While her mutant powers are in use, Wolfsbane has 3 type of physical appearance. She can change completely in a wolf, a hybrid form taking on characteristics of both a human and wolf and her absolute form taking on the form of a huge werewolf like creature. She is covered with reddish brown fur and grew a tail. She also had reversed knee joints, an elongated snout and razor edged canines.
Although Wolfsbane can transform herself into a wolf, she is not a werewolf in the sense that there is nothing supernatural about her power. Her transformations are not dependent on the phases of the moon, and she has the same vulnerabilities to injury as does a normal wolf when she is in lupine form, and no special weakness against silver.
Wolfsbane is capable of moving and running faster than the finest athlete while in her wolf form. Wolfsbane's muscles produce far less fatigue toxins during physical activity than the muscles of an average human. She can exert herself at peak capacity for several hours before fatigue impairs her. Combined with her regenerative healing ability it allows for Wolfsbane to be more durable in battle, thus allowing her to sustain more damage than the average.
Wolfsbane possesses a healing factor, though not on par with Wolverine. She is able heal her wounds and restore her health at an accelerated rate.
Wolfsbane's natural agility, balance and coordination are enhanced to increased levels, similar to that of a wolf, but even greater then. She possesses reflexes enhanced beyond that of the average human, match that of a wolf but greater.
Rahne shares a telepathic rapport between both herself and longtime best friend Danielle Moonstar. This rapport allows both of them to mentally communicate with each other over long distances. It also allows one another to know when the other is in great pain.
She possesses super-humanly acute senses of sight, smell, taste and hearing comparable to, though incredibly stronger than, those of some animals such as dogs, cats and wolves.
Wolfsbane possesses claws at the tip of each finger. These claws are capable of cutting most conventional materials including flesh, bone, wood, stone, and some types of metals. She also has elongated canine teeth that she can use to rend flesh or even break through bone in combat situations.In wolf form, Wolfsbane tail provides greater balance allowing for more precise athletic movement.
Wolfsbane possesses superhuman strength enabling her to lift about 1 ton, though in her "absolute form her strength levels have yet to be measured.
Wolfsbane is a formidable hand to hand combatant, trained in self defense in combat training by none other than the likes of Cable, Wolverine, Nightcrawler and Havok. A fearsome opponent she has held her own against the likes of Wolverine, Sabretooth and Feral many times over.
She is also an excellent tracker and hunter due to her enhanced senses with her mutant talents.
Rahne's surrogate mother, Moira MacTaggert was, when alive, the world's leading genetics. Rahne was eager to learn and apprenticed with her mother and gave large amount of valuable knowledge. Rahne is skilled at Advanced First-Aid and Emergency Medical Training.
Wolfsbane is able to determine if someone is lying by judging the person's emotional stated. She simply observes the changes in their heat patterns and the scents they give off.
Wolfsbane enhanced sight grants her the ability to see ultraviolet and infrared portions of the electromagnetic spectrum; thus allowing her to perceive objects or people in patterns of heat. She is also able to see is absolute darkness.
Rahne, as a result of her mutant nature, was initially unable to grow her hair (in human form) longer then a crop top. Though never explained, it may be as a result of internal mental inhibitors. For Rahne, beauty was a negative thing, as her father thought of her. She may have affected her ability to grow her hair, herself.
Wolfsbane previously was only able to change in a wolf or wolf/human hybrid, only later her absolute form was granted to her. While she was a mutate on Muir Island, she was experimented on by their scientist. This occurred when she was being bonded and stuck into her mutate suit. Due to the further mutation they processed on her they inadvertently induced, potentially, a secondary mutation or simply gave her a power increase. Either way, the result allowed for greater size and strength. Roughly 8' on all four legs, 12' on her hind legs. A mass weighing nearly 1000lbs and an increase in all her other mutant attributes. The source of the additional mass is assumed to come from an extra dimensional source, but not yet revealed.
Wolfsbane retains virtually all of her human intelligence when she is in lupine form. However, as a wolf she might have difficulty at pattern recognition, or in comprehending particularly complicated concepts which she could understand somewhat more easily as a human. She does not possess a wolf's instincts, and therefore must learn how to use her lupine abilities. However, when she is in lupine form, since she then has a wolf's vocal organs, she cannot speak. But as a wolf she can achieve a degree of telepathic communication with her fellow ex-New Mutant Dani Moonstar.
Wolfsbane's "transitional form" combines elements of her human and lupine forms. In it she retains her full intelligence and is capable of speech. In transitional form Wolfsbane is less agile than she is as a wolf, but she is stronger than she is as a human being. She can stand erect and use her front paws as hands. She is still covered with fur in her transitional form, but the coat is thinner. At least some of her senses in transitional form are more acute than they are in her human form.
Wolfsbane's lupine and transitional forms are more massive than her human form. The source of this additional mass is unknown. For a short time Wolfsbane gained Dagger's ability to project light and she gained a new beautiful human body and upgraded wolf transformation.
