Leonhart is a lion-like beast with a very large figure that stands at least two meters in height with thick dark sienna brown fur that covers his large muscular body with a soft bushy tail, a pair of curved charcoal black horns on his head, a thick crow black mane that extends down to his middle chest, and black razor-sharp claws that can easily rip and shred enemies to pieces, and a pair of thin crimson eyes that has a stare that can easily frighten anyone that he looks at. He wears a simple formal attire that consists of an aegean blue long-sleeved tunic with gold details, a white sash around the waist, ivory white trousers, and a black cape with a purple interior.
