Deku is a short fit hero with green short hair and green eyes. Deku realized that his classmates at U.A. High School felt stressed after fighting villains, so Deku uses a shrinking device to create miature cities, complete with sentient tiny people, so his classmates like Bakugo, Shoto, Kirishima, and Denki relive stress. Deku can recreate the tiny cities each time they get destroyed to be used again.
