Shinya Kamihara

Shinya is compact, lean and muscular, and noticeably short next to the other heroes at his rank. Gray hair falls in three sharp points across the right half of his face, above dark gray eyes and a mask that hides his nose, his mouth and a thin moustache. The costume is a ninja's: a blue face wrap tied off at the back with red yarn, red shinobi shozoku under a blue robe, arms sleeved in thin dark cloth that disappears into white forearm covers, red straps trailing outward from belt and robe, a gold mask fixed to the right shoulder, a red scarf patched in white at the front, and blue socks in yellow zori.

All of that is undone in the Final War. Zenith reduces him to a single strand of thread with a miniature head at the end, and recovery is slow: tiny arms with five tiny fingers come back first, and eight years later he is full sized again apart from a left arm still made of thread, brown and slight in the manga, red and normally proportioned in the anime. Age has put lines around his eyes, the hair is shorter now, and the long fringe covers the left side of his face instead of the right.

He carries himself the way a shinobi is supposed to, quiet and centered, and he is the one who talks his colleagues down when a situation starts coming apart. The mind underneath is quick: one look at All For One using Warping was enough for him to work out how the Quirk functioned. He moves early to keep a fight from happening at all and does not flinch from the worst version of one, which is how a man his size ended up standing in front of All For One to buy All Might room.

The clearest statement of who he is came at the end. With Katsuki Bakugo's heart stopped by Tomura Shigaraki, Shinya volunteered to go inside the boy and stitch him back together, knowing the cost would likely be his own life, and did it anyway.

Foldabody flattens and stretches any part of him at will until he is effectively a razor-edged string, and the transformation happens faster than sound. He uses it to slip through doorframes and gaps and open passages that should not exist, to fight in the air by folding himself into a drill and steering around a target, and above all to stab: a body folded into a blade reaches an opponent before the opponent registers movement, and a strike placed correctly cuts blood to the brain and drops them unconscious. The cost is written into the Quirk. Stretched too thin, he burns lifespan, and enough of it leaves him fading away.

He sat fifth in the national rankings and moved up to fourth when All Might retired, having mastered the Quirk completely and folded it into a ninja's method. At Kamino he ran both Kurogiri and a low-grade Nomu through before either could act, taking Kurogiri out of the fight before a single warp; Magne could not even work out what had happened, the speed was so far past her. He and Endeavor later teamed up to relieve a struggling All Might against All For One and walked away unhurt. During the Paranormal Liberation War he cut through Front soldiers on his own and beat Re-Destro, the Meta Liberation Army's former leader, taking only moderate damage for it. Analysis matters as much as speed for him; when Nomu began arriving at the hideout through warps nobody could account for, he deduced that a second party was doing the warping and was proven right by All For One.

Fishhook Snag, Spiral Spear Hand, Pulp-Thread Throttle and Thousand Sheet Pierce all run on the same principle of twisting himself into a point, whether to drag an enemy back, halt them, coil around and perforate them, or knock them out by cutting off their circulation. Substitution Jutsu swaps him with a log an instant before a strike lands. Zenith is Thousand Sheet Pierce taken to its limit, stretching him far enough to enter another person's body and act as surgical suture. He founded U.A.'s Textile Arts Club with Tsunagu Hakamada, nominally a club and actually a way for two students with similar Quirks to train.
