All Back-Man

A jacket carrying the words 'All-Back-Man' across the back is part of the look for this young hero. His light-colored hair is combed straight back, framed by sideburns above a well-defined jawline, and the hero name itself is a nod to that slicked style.

By his trade's standards All Back-Man is thoroughly ordinary, and he knows it, though he once claimed to rank among the stronger members of the C-Class. He is described as rough like a brawler yet composed like a strategist, and he favors hand-to-hand fighting. His defining moment comes when the Deep Sea King storms an evacuation shelter: he is the first hero to stand up, offering to surrender on everyone's behalf in the hope of sparing their lives.

Frightened enough that he wets himself, he still weighs actually taking on the sea monster to buy time until a stronger hero could arrive, which shows he is no coward. The beating that follows shatters his confidence, and he walks away from heroics out of shame and a sense that he never deserved the title.

Alongside Sneck, Jet Nice Guy, and Bunbun Man, All Back-Man tries to hold the line against the Deep Sea King and protect the civilians, but the four are swiftly overwhelmed and knocked out. He retires in the aftermath. He is presumed to return to duty later, since he turns up among the crowd of heroes during the Monster Association Arc, arriving at the ruined Z-City Ghost Town after Tatsumaki tears out the Monster Association's headquarters. There the heroes debate what to do with the depowered Garou until King steps in to halt the impromptu trial.

He appears again in the Psychic Sisters Arc, present at the Hero Association's A-City headquarters when Tatsumaki battles Apollo in the underground levels, and he joins the others to investigate once the alarm sounds.
