Bio: Gatecrasher's constant companion. He is a small, sentient being who can teleport himself and his companions across vast distances. Yap can detect the psychic auras of individuals and the electron patterns created by such things as Captain Britain's battlesuit. By these means Yap can track down specific individuals. Yap has telepathic powers whose limits are undefined. Yap has an intense emotional dependency on Gatecrasher and refers to her as "mother," usually to Gatecrasher's annoyance.
