Izuku Midoriya (緑みどり谷や出いず久く Midoriya Izuku), also known as Deku (デク Deku?), is the main protagonist of the My Hero Academia manga and anime series.

Even though Izuku was born Quirkless, he manages to catch the attention of the legendary hero All Might due to his innate heroism and a strong sense of justice, and has since become his close pupil, as well as a student in Class 1-A at U.A. High School. All Might passed on his transferable Quirk to Izuku, making him the ninth holder of One For All.

Following the Paranormal Liberation War, with Tomura Shigaraki and All For One actively targeting Izuku for his Quirk, he decided to leave U.A. before finishing his first year to keep his classmates out of harm’s way. He is still continuing to fight villains.

Izuku is somewhat short for his age, his round face framed by a short mess of fluffy dark-green hair which sticks up at odd angles around his head, casting noticeably dark shadows onto itself. His eyes are large and somewhat circular, their irises the same green color as his hair, which at times are very watery, and are usually stretched quite wide, giving him an innocent, energized appearance. He has a set of four symmetrical freckles in diamond formations, one on each cheek, but despite these prominent traits, he’s often described by others as being plain-looking.

Though he was initially very skinny, Izuku has gained toned muscles after his ten months of extensive training with All Might, and as the series progresses, these are shown to become more developed and defined as he gradually grows stronger.
