Kido has the build of an average adult man whose skin is covered by either strips of clothing or bandages. His signature bandages cover his entire face and as well as parts of his arms and hands. He wears a flak jacket over a short-sleeved shirt as a part of his hero costume.
Along with the rest of the Flaming Sidekickers, Kido gives a hot welcome to Izuku Midoriya, Katsuki Bakugo, and Shoto once they arrive at the Endeavor Agency. Later, he helps to apprehend a villain defeated by Endeavor.
