Mezo Shoji is a student whose Quirk is Dupli-Arms, which allows him to grow individual body organs at the tips of four webbed tentacles growing from his shoulders. Despite his frightening appearance, Mezo is a very friendly and gentle person who will work nicely with anyone. He is not the type to hold grudges, showing no ill will towards those that harm him unwillingly. Mezo is quite selfless and willing to risk his life for anyone. He can be empathetic and understanding, but still shows a sense of maturity and responsibility that prevents him from acting under emotional impulses, even if he feels regretful about it. He is very protective of his classmates, especially if they are hurt or injured.
