Personality
A typical hero of Hero Association, Bone is a proud and glory-craving hero who want to defeat highly powered Mysterious Being to gain fame in the public rather than saving innocent people. His craving for fame is so great that he wants his achievement to be told to the next generation of mankind.

Pork Cutlet Bow
Bone Bone was one of the many heroes which tried to attack the monster that was devastating a police station in order to get credits, since it was an important emergency. However, he arrives at the scene when Saitama has already killed the monster.

Abilities and Powers
As a B-Class hero, it can be assumed that Bone Bone is a fairly skilled combatant. Though his rank implies he isn't very strong by B-Class standards.

Enhanced Speed and Reflexes: Bone Bone was able to save Red Muffler from a bus thrown by Hundred eyed Octopus.

High Bone Density: Bone Bone was born with the highly dense bone structure, which makes his body tough as armor. Furthermore, he also can increase his bone density further by drinking milk or consuming high calcium foods. However, all of these are not enough to withstand the strike from the tentacle of Hundred-Eye Octopus, which breaks every single bone in his body.
