Double Hole

A cybernetic device sheathes Double Hole's oversized nostrils and spreads across his cheeks. He keeps his black hair at a medium length and fights barefoot in a red training gi cinched by a black belt, an infinity symbol stitched in red over the upper left of his chest.

Little has been shown of his temperament, but he spoke almost nothing throughout the battle with the Monster Association, pointing to a serious, reserved nature.

Double Hole joins the support team for the raid on the Monster Association headquarters. Ambushed at the entrance, he fights beside his peers, at one point grabbing a primate monster by the nostrils, whirling it through the air, then drawing a deep breath and firing a blast from his cybernetic nose that rips through the beast and several others behind it. His nose cannon does far less against tougher foes, and Rhino Wrestler dismisses one such blast as a mere twelve out of a hundred. Once the S-Class heroes clear the second wave, he waits above ground with the support squad until the executive Nyan cuts him and many others down with strikes too fast to follow. Sekingar carries the wounded to safety, and Double Hole is still breathing when Drive Knight finishes Nyan off.

He resurfaces in the Neo Heroes era, running into the wanted man 'A' beside fellow hero Feather. Sekingar rates him a capable combatant and offers him as proof that a hero's rank and true skill do not always line up, since he clears weak monsters with ease yet stands helpless before Demon-level opponents. In the extra chapters he enters the Hero Costume Contest and battles Vaccine Man, and after that fight he rises to Rank 29. His hero name was originally given as Double Fall.
