Sword Kill
CharacterSword Kill arms the Serpenters brothers with blades that unfold straight out of their own bodies, accordion style. A Transformation Quirk introduced in World Heroes' Mission, it turns considerably nastier the moment Trigger enters their system.
Overview
The Serpenters brothers wield Sword Kill, a Transformation Quirk that debuted in the film My Hero Academia: World Heroes' Mission. Despite the weapons growing out of the body itself, the ability is classified as long-range.
It should not be confused with Swordkil, the villain from My Hero Academia: Two Heroes.
Mechanics
Blades emerge from the arms and shoulders of whoever carries the Quirk. None of them are rigid: each one flexes and collapses, extending and retracting much the way an accordion does, which lets the wielder reach across distances an ordinary sword could never cover.
Trigger changes the picture. Dosed with the drug, a Serpenter can field as many as six blades at once, some of them pushing out of his mouth, while his face twists into something sharper and more serpentine.
