Mantenmaru is a large boar and is Shussemaru's fellow mascot at the temple where prayer tablets are sold with Shussemaru's likeness on them. It is implied that he is as hideous as Shussemaru. After Shussemaru had a beautiful painting of himself made and Hinako drained his battle aura, the temple priest decided to sell paintings of the temple's other sacred animal, Mantenmaru. After Ranma commented about the painting's hideousness, Mantenmaru's wrath was evoked.
