Shishido resembles a lion, with a long spiky hair that resembles the mane of a lion. His hero costume consists of a large amount of fur, with seceral spikes both in front and on his back, positioned so that they resemble fangs; and a black mask that covers his mouth, decorated to resemble a lion's maw.
His abilities are yet to be shown but he is implied to be a very strong hero since he's the No. 13 hero on the Hero Billboard Chart JP.
- Shishi can mean "Lion" in japanese.
- Shishido is based on the character of the same name from Horikoshi's previous work, Omagadoki Zoo.
