Noteworthy techniques and abilities
Clones: Ectoplasm's Quirk gives him the ability to produce streams of ectoplasm from his mouth and transform it into clones of himself. He can create as many as thirty clones at once, though, it is possible for him to push his limit to thirty-six on a good day. He can also produce a single giant clone of himself, although this sacrifices his ability to produce normal sized ones for the time being. His clones can be defeated with a strong blow, but otherwise, only Ectoplasm can dispel them.
- Forced Internment Giant Bites: Ectoplasm shoots ectoplasm from his mouth and transforms it into a giant clone of himself. The giant Ectoplasm clone then overwhelms and traps the enemy with a huge bite. He first used this during final exams
