Boomerang Mario is one of Mario's endless Power-Ups. It first appeared in Super Mario 3D Land, and is accessible by collecting a Boomerang Flower.
Boomerang Mario also appeared In New Super Mario Bros. Omega. In this game, the player should collect a Boomerang Suit to access this suit.
Like his cousins, Boomerang Mario can throw a boomerang just like other Boomerang Bros. He's also invulnerable to some fireballs.
