Boomerang Bros. (Hermanos Boomerang in Spanish) are a type of Hammer Bros. who, instead of throwing hammers, use Boomerangs as weapons. In Super Mario Bros. 3, Boomerang Bros. appear as enemies in several levels, commonly desert levels. In Mario Super Sluggers, they are alternate colors Hammer Bro. They appear in many side-scrolling games such as the New Super Mario Bros. series. They wear a blue helmet and a blue shell and matching shoes. In the Paper Mario series they were gray instead but were changed back to blue in Paper Mario: Sticker Star.
