Griffin
From Jenny Everywhere Wiki
Griffins were beings with mammal body-plans and wings on their backs on top of four ordinary limbs. They had eagle-like heads with feline ears.
The Griffins of the Sixth Realm were sentient and bipedal. Merv the Griffin, one such Grififn, was once summoned to another world by a witch and bound to said world until he accomplished a particular task (in this case, slaying Captain Evening). (COMIC: For Whom The Toll Bells)
