Leo

Leo is a character that appears in WarioWare: Get It Together!. He is a ninja with the ability to control and transform into animals. He serves as the antagonist during Kat & 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 & 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 uses a ninja technique called "Puppetry", enabling him to take control of the animals, which he uses to cause trouble to the village residents. Kat & Ana then arrive, cast a sleeping spell on one of the animals, and confront Leo, who summons the animals against them and uses a ninja technique called "Lion's Roar", transforming himself into a lion.

Leo's lion form makes a cameo in Kat & Ana's stage itself. When the boss microgame is completed, it appears, turns friendly, and dances off-screen.

Leo can also be seen together with Kat & Ana in some of the images in their galleries, as well as in the cast credits.
