Battery Man

Youthful and light-brown-haired, Battery Man encases most of his body in a pale-blue mechanical suit. A pair of orange-tinted glasses completes the look.

The series reveals almost nothing about his temperament, leaving his personality largely a blank.

When word spreads of a monster haunting the Z-City ghost town after it flattens Golden Ball and Spring Mustachio, Battery Man rushes over with a crowd of other heroes, only to reach the site after Saitama has already put the creature down. In the Super Fight arc he joins the many heroes who throw themselves at the Hundred-Eyes Octopus, is beaten alongside them, and is pulled to safety by Bone and Red Muffler. He surfaces again once Tatsumaki turns Z-City inside out by wrecking the Monster Association Headquarters, gathering with fellow heroes to debate what should be done with a drained Garou until King steps in to interrupt the trial.

His rank hints that he is respectable by C-Class measures, though his fighting relies on a single tool. Strapped to his back sits a battery pack that lets him electrify his blows with powerful charges, even if the device runs at rather poor efficiency.
