Leo is a character that appears in WarioWare: Get It Together! He is a ninja with animal metamorphosis and control powers and serves as the antagonist during Kat and Ana's level Nature in the game's Story mode. Leo wears a purple sleeveless shirt, black fluffy pants, yellow shoes, a fluffy yellow scarf, and yellow bracelets, similar to Kat and Ana's clothing. He has cyan eyes and purple hair, with bangs that cover one of his eyes.

Leo first appears when he arrives at Sleepytown Village and casts ninja spell "Puppetry", enabling him to take control of the animals, which he uses to cause trouble to the village residents. Kat and Ana then arrive, cast a sleeping spell on one of the animals, and confront Leo, who summons the animals against them and casts ninja spell "Lion's Roar", transforming himself into a lion.
