History

Wendy Taylor, along with her family, was kidnapped by Weapon-X and taken to the Neverland concentration camp. In Neverland, mutants deemed useful (like the Taylors) were branded with a green M on their hands, whilst those deemed less useful were branded with a red M and executed.

Wendy's mother helped her and her brother escape Neverland with the aid of a scientist called Dr. Windsor, only for it later to turn out that Dr. Windsor was Mr. Sinister in disguise who started experimenting on the children.

Powers

Wendy can transform into a gaseous state, also after Mr. Sinister started experimenting on her she started growing red spikes out of her body.
