Ursa is a Kryptonian imprisoned in the Phantom Zone. She created a chemical that she used to help her, Zod and Faora create a monster called the Hunter, a beast capable of penetrating the Phantom Zone barrier and capable of absorbing any substance he touches. All this was done in order to help them escape the Phantom Zone and get revenge on Superman, whose father had imprisoned them there.
Ursa was originally seen in the films "Superman: The Movie" and "Superman II." She is later introduced to the universe of the comic books.
