Mythical creatures. That’s a belief that 99% of the world holds. A belief that was shattered for the Mighty Union when one appeared on their mansion grounds looking for Mickey. He agreed to let Mickey be, for now, as long as they hunted down the other creatures Mickey’s scientific transformation had created. When this was done (by the Union’s new black ops team) the werewolf thanked them and would let his people know that the Mighty Union could be trusted.
The black ops team came into contact with werewolves once again when they went to Venezuela and discovered Corvin experimenting on them, and a hunter come to destroy them. The data they brought back for the Union revealed that this was the source of what had transformed Mickey.
