Born and raised in Scotland, Rahne Sinclair learned she was a mutant at the tender age of fourteen. While being pursued by an angry mob of townsfolk, Rahne discovered she had the power of lycanthropy--the ability to morph into a wolf! Brought in by Professor Charles Xavier, Wolfsbane served on both the New Mutants and the government-sponsored X-Factor. Now she has returned to her foster mother, Moira MacTaggert, on Muir Island to join the international mutant team of Excalibur!
