"Ogama in his true form, who has lived through hundreds of years and transformed into a Yo-kai. He was once allied with the most powerful ninja in the world, and his bravery is widely known, for he was the toad with a ninja on his back."
In his Lightside form, Ogama looks very much like his original counterpart. There are slight changes though, such as his older appearance and longer blue vest.
In his Shadowside form, Ogama resembles a large frog or toad with a large shoulder guard on.
