Luke is a male anthropomorphic Griffin and native to the USA. Being a griffon, Luke's body possesses bird and feline body parts; specifically, his lower half resembles that of a mountain lion, while his upper body resembles a bald eagle. Luke is often seen wearing his dark blue tank top and white camouflage-pattern pants. His other notable outfit of his is a blue speedo with many white stars; the item clearly modeled after the American flag.
