from the lovely  RyokoNoKalo

This is Leo, a merlion who is full of pride and a noble in Poseidon City. He is a charmer and of course loves when the female merfurs comment on his beautiful fur, tail, and body whenever he goes out to swim to his favorite place, The Water Lady Club venue where he is the favorite their with the ladies. However, his pride does get to him when someone turns him down or doesn't get the attention, even when Maku comes around. Although friends, Leo consider Maku to be his rival even though the merwolf is more than just a noble himself.

Despite this, Leo can be a good friend; but can be prideful and often full of himself, but he is a friend and would help out but smooth talking someone in the Water Lady Club if they know anything.
