Minorhinoceros is one of the five Demon Guards at Impel Down. He is a "resurrected" type of Zoan Devil Fruit user, who has eaten a Devil Fruit that turns himself into a rhinoceros.
Appearance
In the form of Zoan, Minorhinoceros is a large two-legged rhinoceros. He has cute eyes, big lips, and a runny nose like the other Demon Guard. He used two spiked batons as weapons.
Personality
He was very bloodthirsty, like the other three Guardian Devils, despite having a ridiculous appearance, and the prisoners were afraid of him. However, he acknowledged Sadi-chan's superiority in the fight, even frightened when Sadi-chan was angry at the failure he had done.
Ability and Strength
As one of the Guardian Devils of Impel Down under Sadi-chan, Minorhinoceros is in charge of torturing and guarding various prisoners.
Weapon
He used two barbed iron batons as weapons.
Devil Fruit
He had eaten an unnamed Zoan-type Devil Fruit which allowed him to turn into a rhinoceros. Because he was a "Resurrected Zoan", he was able to recover faster than Zoan users normally, even after receiving high amounts of damage.
