Baku is a non-player character and leader of the infamous Tantalus Theater Troupe in Final Fantasy IX. He plays King Leo in the troupe's production of the play I Want to Be Your Canary. Tantalus' home base is in Lindblum's Theater District.
Baku is stocky and strong. His skin is grey, and he has a purple beard and mustache; the body hair on his arms and legs is also purple. He has pig-like features, with a large nose and long furry ears. Baku wears aviator goggles; an orange waistcoat held closed with rope over a white collared shirt with sleeves to his elbows; brown wristbands; green shorts; brown belt, and white and brown boots. During the first battle with Baku he wears a blue dragon mask over his face. As King Leo Baku wears a voluminous red and green, floor-length coat trimmed with fur; gold bands on his arms; a black and red shirt; dark green trousers and brown boots. He appears to be wearing a silver wig, though his aviator goggles remain.
Baku is close to his Tantalus "family". This does not prevent him from being their boss and sometimes giving them a sound beating to keep them in line, but he is loyal to those he is close to and is willing to help them. He sneezes often and has great trouble remembering Doctor Tot's name, instead calling him Ted, Toot or Tootsie.
