Afterwards, Skin accepted an invitation to enroll in the Massachusetts Academy, a school for mutants owned by Emma Frost. As a member of Generation X, Skin was joined by Synch, Jubilee, Husk, and M (and later by Chamber, Penance, and Mondo). During his stay at the Massachusetts Academy, Skin became close friends with Chamber because neither could pass for normal humans in public, and he always found time to playfully flirt with Husk, Jubilee (whom he nicknamed Jubecita), and M. Skin was also hunted by a mutant-killing vigilante known as the X-Cutioner who believed Skin responsible for the death of Angelo Espinosa. The X-Cutioner did not know that Skin, in fact, "was" Angelo Espinosa. Skin and Chamber succeeded in defeating the vigilante, but kept the secret.
