Minorhinoceros is one of the five Demon Guards of Impel Down. He is an "awakened" Zoan Devil Fruit user, having eaten a Devil Fruit that turned him into a rhino.
Abilities and Powers
As one of the Demon Guards of Impel Down under Sadi-chan, Minorhinoceros is in charge of torturing and guarding various prisoners.
He wields two iron clubs, covered with spikes.
He has eaten an as-of-yet unnamed Zoan type Devil Fruit that allows him to become a rhinoceros. Because he is an "Awakened Zoan", he is able to recover much more rapidly that normal Zoan users, even after suffering high amounts of damage.
In the past history of Impel Down, the Demon Guards were one of the main threats in Impel Down; due to their amazing ferocity, thirst for blood and their incredible strength.

The Minorhinoceros was called to Level 4 to try stop the riot that had started to take place, due to Luffy and Ivankov. However, Jinbe put an end to the Minorhinoceros' rampage by sending him flying with a powerful uppercut. After Sadi-chan recovers from her fight with Ivankov, she whips the Minorhinoceros and other Demon Guards and orders them to go to Level 1. They arrive in time to attack Buggy's group, but are later defeated again by Luffy and Jinbe.
