All Back-Man is a C-Class hero stationed in J-City — a 26-year-old standing 182 centimeters tall, whose hero name references his slicked-back hairstyle. Like many C-Class heroes outside the story's main cast, he appears primarily as part of the Hero Association's rank and file rather than in a major individual storyline, representing the wide base of ordinary heroes doing local hero work across the various cities.
An average-height, lean, athletic man whose dark hair is meticulously slicked back — the source of his hero name. Wears a dark, high-collared tracksuit-style hero suit with light racing-stripe trim.
Courageous, vocal, and selfless — he announces his own arrival in battle specifically to boost civilian morale. Fully aware he’s outmatched by Demon-level threats, yet refuses to retreat when lives are on the line, and works well under higher-ranked leads without ego.
Assigned to Class C, established as a reliable street-level hero before being swept into the major Seafolk disaster in City J.
Stands with a small group of Class C heroes as the last line of defense at a City J shelter after Snek falls to the Deep Sea King, charging in shouting his own name to rally the crowd — and is incapacitated almost instantly. Recovers in the hospital alongside Mumen Rider and Jet Niceguy, present when Saitama visits the ward. Later recruited onto the Surface Support Team during the Monster Association raid, helping hold the perimeter against fleeing monsters.
Standard hero-level physical conditioning and hand-to-hand combat suited for human criminals or Wolf-level monsters, plus trained crowd-control and evacuation protocols. No specialized weapons or supernatural powers, and outclassed by anything Tiger-level or higher.
vs. Deep Sea King — Ch. 26
Tried to defend a shelter from the Seafolk King. Overwhelming defeat, but it showed real bravery against a threat that outclassed him completely.
vs. Monster Association Surface Swarm — Ch. 148
Part of the larger hero group holding the line against monsters fleeing the collapsing base. Tactical win.
Major: Ch. 26. Minor: Ch. 25, 28, 29, 92, 94, 148, 151. Mentioned only: Ch. 38.
Snek: a Class A senior he respects and fought beside in City J. Jet Niceguy & Bunbunman: fellow Class C heroes bonded through the same shelter trauma. Mumen Rider: a hospital-ward peer sharing a similar never-give-up outlook.
“I... I’m a hero too! Allback-man! Into action!” — charging the Deep Sea King
His selection for the high-stakes Monster Association Surface Support Team, despite a quick early defeat, suggests the Association considers him a reliable Class C veteran.
