Hiroshi Shibata

Hiroshi Shibata (柴田宏, Shibata Hiroshi) is a (formerly powerful) esper and a former member of the terrorist organisation Claw as a part of the Ultimate 5.

Appearance
While in his prime, Shibata was a large, imposing, incredibly muscular person, with tanned skin. After his psychically-grown muscles withered, he slimmed down considerably with his cheeks becoming noticeably hollowed. He has narrow eyes, thick eyebrows and spiky hair. He wears a sweater and pants that stretch when he grows in muscle mass however, the sweater ripped when it reached its limit.

Personality
Shibata is not the sharpest tool in the box and has a very straightforward outlook to life.

World Domination Arc
He defeated Udo.

He attacked Reigen's building with a group of espers in order to find and takeout Mob. After Mob escaped the building, Shibata destructively followed, encountering Onigawara and the Body Improvement Club in the process. They attacked him but he easily defeated them. Dimple then possessed Musashi Goda, unlocking the kid's full muscular strength, leading to Shibata's defeat. However, Shibata got back to his feet before being psychically flattened by a freshly awakened Mob. The Body Improvement Club members then took him to the hospital.

At some point after Claw's attack, Shibata is now job-hunting with the muscles he had developed with psychic power having atrophied immensely. Whenever asked about his personal history during interviews, a reply of "I was in the Ultimate 5" seems to go over well. Shibata has failed 20 interviews and counting, but still doesn't understand why.

Powers & Abilities
Shibata can psychically control his muscle mass via his brain, which sends signals non-stop to his muscles, causing them to expand, unless he stops it. If he is rendered unconscious, he becomes unable to hold back these signals, causing his muscles mass to exponentially increase.
