Manako

Squat and rounded like a little cyclops, Manako has skin of a pale pink and one large green eye. A pair of small horns top her head, sharp teeth fill her mouth, and a thick black belt is usually pulled up over that mouth to hide it.

Above all else Manako is a coward. During the heroes' assault on the Monster Association base she shut herself in a restroom, hoping to sit out the fighting, and would not budge even once told the attack had begun. The S-Class terrify her, and she recoils in panic when Flashy Flash bursts into her hiding place; artists tend to draw her drenched in sweat and permanently jittery.

Yet that fear breeds treachery. Certain she will be discarded and killed the instant she stops being useful, she repeatedly plots against her captors, meaning to tip their minecart off a severed rail into a chasm and later to bash Saitama with a rock while they lie buried. Each time, her nerve deserts her at the crucial moment.

Grabbed in the restroom of the Monster Association Headquarters, Manako was made to guide Saitama and Flash toward the Monster King, Orochi. Steering a minecart through the tunnels, she meant to derail it at a junction and drag everyone to their deaths, but the sight of the sheer drop unnerved her and she backed out. When mining monsters ambushed the group at an excavation site, the two heroes cut them down instantly; Manako almost tumbled to her doom until Saitama caught her, letting go of the gold he had been pocketing to do it.

The trio then ran into the merged Psykos and Orochi. The monster's attempt to absorb Saitama simply slid off his bald scalp, and a single punch from him briefly wiped out the Psykos half. Soon after, Tatsumaki tore the entire headquarters up out of the earth; Saitama shielded the group from being crushed, but left them stranded in pitch darkness. Trying to knock him out with a heavy rock, Manako instead exposed Flash pinned in the rubble, and her startled eye flared to light, revealing the whole cavern.

As the fight raged overhead, Saitama and Manako labored to free Flash. During the wait she showed Saitama how cinching her belt tight blunted her hunger, a strangely warm exchange that ended with the pair swapping names at last. Once Flash was nearly loose, Saitama flung aside a bizarre, enormously heavy cube he had carried. A voice pressed into their minds, urging them to lay hands on it and make a wish, before Blast arrived through a portal, described what the cube was, and sent it off. Spotting the monster among them, he relaxed only after Saitama offhandedly called her their tour guide and lamp, then warped all three up to the surface.

On her own again once the heroes left, Manako later found a beaten Flash, only for Sweet Mask to take her for an assassin and strike at her. A surging ship and a flood swept her off before Pig God gulped her and many others down to ferry them clear. In the doomed Ominous Future timeline, Garou's cosmic radiation claimed her as she spent her last strength reaching the unconscious Tareo, though Saitama's later trip through time undid that end and restored her once Garou fell fast; where she went afterward is unrecorded. In the Neo Heroes era both Saitama and Flash hunted for her, prizing her as one of the few to have brushed against the being they call God. King stumbled onto her at the Final Training Ground and she bolted, but he and Saitama coaxed her out with food and delivered her to the Hero Association, where Blast met her once more.

Weak as she supposedly is, Manako holds real gifts. Her arms can heave sizable rocks and clung to Flash through a battering flood, her eye sees in the dark, and by working her horns in various combinations she casts assorted beams of light, an ordinary glare bright enough to blind Saitama and Flash, a long-range searchlight, a heat-sensing mode, and even x-rays. A retconned chapter reveals she formed as an offshoot spawned during the Psykos experiments that made Gyoro Gyoro, and her very name means eyeball.
