Gmork

Gmork's main mission is to track down and kill Atreyu. He and other dual-matured creatures like him do not possess a world of their own like Fantasticans and humans do. Instead, he is able to travel between worlds, changing into a Fantastican or a human (depending upon the world), but in appearance only. Gmork's knowledge of Fantastica (Fantastia) interested the Manipulators, which is the reason they gave him his mission. However, Gmork never manages to catch up with Atreyu because the latter uses the magical powers of the monster Ygramul's poisonous bite to wish himself to the Southern Oracle.
