Oboro Shirakumo was a highly respected hero and a valued member of Class 2-A at UA High School. He possessed a quirk known as "Cloud," which allowed him to transform into a cloud-like form and manipulate the air around him. Oboro was a dedicated hero who was known for his selflessness and willingness to put himself in harm's way to protect others. Tragically, he lost his life in a battle against All For One while fighting alongside his close friends and fellow heroes, Eraserhead and Present Mic.
