Ryan is one of the characters from Pop'n Music Sunny Park.
I'm the king of beasts. I'm a hungry beast. A dangerous carnivorous type.
And today I'm roaring. Meeeeeaaaat!
Ryan appears to be a lion with blond hair, wearing dark purple pants, and a black belt that contains an animal emblem. Ryan's hair will change into a dull brown color and his weight thinner if no meat is provided, as of his Miss and Lose animations.
Ryan's name is a pun on "lion", because they sound familiar.
