Bio: The Ani-Mator was a geneticist employed by Cameron Hodge to research a means of stopping the process that creates mutants. Dr. Animus instead created a race of "Ani-Mates", which combined the characteristics of human beings and other animals, intending them to be a slave races for humanity.
One of the Ani-Mates, Bird-Brain, escaped the Ani-Mator's island and ultimately befriends the New Mutants. The New Mutants return to the island with Bird-Brain to stop the mad scientist's experiments. The Ani-Mator, now dressed in rags, attempts to shoot and kill Wolfsbane. He instead hits and kills Cypher, who had pushed her out of the way. Magik exiles the Ani-Mator to the dimension of Limbo in retailiation.
Bird-Brain stays on the island to help his animal friends.
