Bio: Zairre was a demonologist and high priest of a Satanist Church. Buck Owen thought that Zairre might be able to free his friend Jack Russell of his lycanthropy curse. Zairre instead had his own plans and became determined to sacrifice Jack, in his werewolf form, to Satan. He captured both Buck and Jack and brought them to a cave where he prepared to sacrifice Jack as soon as he transformed into Werewolf by Night.
As Jack transformed, he was pulled down through the lake in the cave onto a planet from another dimension, Biphasia. He actually had an entire "adventure" there, and upon being returned, was returned to the exact moment he left, as Buck was trying to stop him from murdering Jack.
Zairre was pushed into the water and disappeared. Buck believed him to be dead but Jack figured he must have also been transported to Biphasia.
