Professor Leonardo Lionheart is the headmaster of Haven Academy. He is a member of Ozpin's Group, but his allegiance is in question. In "The Next Step", Salem referred to Lionheart as an informant for her organization, and in "No Safe Haven", he is seen having a meeting with Arthur Watts.
Lionheart is a seemingly middle-aged man with a mane of tan/gray hair and a beard. He has a tanned complexion with brown eyebrows and dark brown eyes.
He wears a great coat with a mantle and has a western neck tie and carries a pocket watch.
On the surface Leonardo Lionheart demonstrates a rather polite and jovial persona, genuinely coming off as a well-meaning and companionate man.
He is also shown to be easily startled and seems to be somewhat timid. Despite this, he is willing to argue with people like Qrow Branwen and seems unafraid to speak his mind to his fellow huntsman. Lionheart also shown to be less impulsive than Qrow, suggesting they wait and figure out a better way to retrieve the Spring Maiden from Raven Branwen, rather than immediately head out to fight the tribe and get to her.
However in front of Salem, he reveals himself to be cowardly, acting subservient and submissive to her and is clearly frightened of her.
- It is incredibly likely that Lionheart alludes to the Cowardly Lion from The Wonderful Wizard of Oz.
