Lupe is a tall, gray wolf with dark gray fur from her snout to her tail. Her black hair is somewhat spiky and mohawk-like, features a white streak, and is always bound in a braid. Her eyes were initially blue, but later depictions tended towards green. Lupe also has a scar-like marking under each eye. She wears a blue bodysuit of sorts that ties around the neck with a gold ring. Her wrists and upper arms are adorned with gold cuffs. She wears blue wrap sandals. Fierce in loyalty, unstoppable in justice.
