Vanessa Tremont was the attending head-nurse at Bradley High School in upper Manhattan, New York. She was romantically involved with one of the instructors, John Ravenhair. Vanessa witnessed the spirit of John's bitter great-grandfather Bison-Black-As-Midnight-Sky take possession of his descendent transforming him into the super-villain known as Black Bison. Vanessa followed Black Bison to Central Park where she found him embroiled in a battle with the super-hero known as Firestorm. Vanessa's love for John gave him the strength to re-assert control over his physical form, enabling him to eschew all traces of his Black Bison identity.
