Overgirl is the only successful result of experimenting to seed a human child with Overman's genetic material. All the others died - except for the horrific aberration known as Antihuman. Overgirl has less than half of Overman's strength, speed, stamina and endurance which is still considerable. She's the first person from Earth-10 to cross the Bleed barrier between Multiverse. She died on New Earth within easy distance of the new Question, and was immediately found by the forces of S.H.A.D.E.
