Some TMNT stuff really isn't for little kids.
Amy Belcher was a typical California valley girl. She contracted a disease from her Vietnam veteran father, and was simultaneously cured and transformed by the villain known as The Creator, who took her then as his erotic servant. He later abandoned her for seeing her as unstable, as she was hearing voices.
Belcher joined the supervillain team known as the Nixed Men, under the name of Sensation. She encountered Officer Dragon alongside them, but is defeated in one punch by him. She fell in love with him and began to reform in prison, changing her name to "She-Dragon".
Involvement with TMNT
An action figure with two variants was released of She-Dragon in the Teenage Mutant Ninja Turtles/Savage Dragon crossover mini-line - one with long hair (looking more like her Sensation incarnation), and one with a mohawk. She also appeared in the pack-in comic that was included with the figures of this line, where she first was shown with the longer hair, before Leonardo cut it into a mohawk during the fight.
