Were-Creatures, most notably werewolves are creatures that are not only one species but two at the same time. Some Werewolves are either allies with vampires or against them. Another type of Were-Creatures are Wercats. In Hellsing the only two were-creatures are The Captain and Schrodinger from Millennium.

As long as he does he is everywhere and nowhere, Thus he can exist wherever, however and even whenever he chooses, this also gives him the ability to teleport.
