Silverclaw possesses the superhuman ability to mimic the physical characteristics of various animals native to rain forests and jungles. Thus far, Lupe has demonstrated the following animal aspects: jaguar, anaconda, cockatoo, monkey, sloth, puma, cheetah, and crocodile. When assuming an animal form, Lupe does not transform fully into the animal. Instead, she assumes a form that combines elements of the animal with her normal human appearance. These were-forms are similar to the transitional forms assumed by other animal shape-shifters, such as the mutants Wolfsbane and Catseye. Each of these forms grant Silverclaw additional abilities. Silverclaw has demonstrated enhanced strength, speed and agility, claws, flight and enhanced senses while transformed. She has also shown the ability to alter her size to some degree, as when she transformed into a giant sloth.
In her powered form, Silverclaw's skin assumes a silvery quality. This silver skin also manifests whenever Silverclaw assumes an animal form. It has not been revealed if Lupe's silver skin is merely cosmetic or if it possesses superhuman qualities of its own. As a shapeshifter, Lupe has complete control of her form. Through force of will, she has overcome powerful transformative enchantments and reverted to her true form.
