It isn't uncommon for superheroes to have unusual origin stories. Bitten by a radioactive spider! A wayward alien baby that crash lands on Earth! Doused in gamma radiation! The wilder the origins, the more interesting the character and the richer their lore. For some heroes, though, their origins don't take place in the pages of a comic, but in animated TV shows due to copyright issues. For Angelica Jones—aka, Firestar—that was exactly what happened and despite her odd debut into the Marvel Universe, she very nearly became a major X-Men antagonist.
