Clones

An Emitter Quirk with long-range reach, Clones belongs to the U.A. teacher Ectoplasm. It works by expelling a viscous substance from the mouth and shaping that substance into duplicates of himself. The Quirk debuts in Chapter 61 and in Episode 13.

Thirty copies is the standard ceiling, rising to thirty-six on a good day, formed from what looks like a glowing fluid. The advantage in numbers lets the duplicates handle a fair count of enemies or swamp a smaller group outright, and Ectoplasm dismisses them whenever he no longer needs them.

Mind is shared across the whole set. Whatever a duplicate witnesses registers with the original even at considerable distance, and since each one can talk, Ectoplasm holds conversations through them. Fragility is the trade-off, as a single strong blow destroys a copy.

He can pour the same material into one enormous duplicate instead, though that choice locks out the smaller ones. The giant version pins people against or inside its body so they cannot move. His Ultimate Move, Giant Bite Detention, follows from this: the huge copy clamps down on an opponent in a bite, a technique he first turns on Tsuyu Asui and Fumikage Tokoyami when the two of them sit their final exam.

Ectoplasm alone uses Clones. The Quirk suits any job calling for many bodies, which places him among the most effective instructors at U.A., since the copies let him attend to students one at a time. He also runs surveillance with it, sending duplicates out to patrol wide stretches of ground.
