Other distinguishing features
: Due to further artificial mutation induced in Genosha, Wolfsbane can reach a height of roughly 8' and a weight of over 400 lbs. in her transitional form, and roughly 12' (when standing on her hind legs) and a weight of over 1000 lbs. in her "absolute" lupine form. The source of the additional mass is presumably extra-dimensional.

Powers
: Wolfsbane is a mutant metamorph who can, through mental concentration, transform herself into a wolf, while retaining most of her human intelligence, or into a transitional form which combines both human and lupine aspects. She cannot adopt any other form but these, nor can she take the form of different kinds of wolves. Her wolf form always has the same physical characteristics, which are those of a wolf a few months short of adulthood. Presumably when Wolfsbane herself becomes an adult, her lupine form will be that of an adult wolf.

In human form Wolfsbane possesses the normal human strength of a girl of her age, height, and build who engages in intensive regular exercise. In her lupine and transitional forms, Wolfsbane's strength is heightened, but not to a superhuman degree.

    Although Wolfsbane can transform herself into a wolf, she is not a werewolf; in other words, 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.

    Wolfsbane's transformations are brought about only as a conscious act of will on her part, although it is possible that she might turn into a wolf without willing to do so if she were sufficiently frightened.

    In lupine form, Wolfsbane's strength, speed, reflexes and senses are similar to those of a wolf's, but are also heightened beyond those possessed by a real wolf. In lupine form Wolfsbane can see into the ultraviolet and infrared portions of the electromagnetic spectrum. As a result, as a wolf she perceives things as patterns of heat. Thus, she can see things even in absolute darkness (in terms of what is "visible light" to ordinary humans). As a wolf she can hear sounds that are beyond the range of human hearing. When she is in lupine form she can also detect scents that ordinary humans cannot, and therefore, she can trail someone by scent just as a wolf or dog can. As a wolf Wolfsbane can judge a person's emotional state and detect any changes in that state as they occur through observing the heat patterns and scents that person gives off.

    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 Moonstar, Dani Moonstar (see 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.
