Boomerang Bro.

Boomerang Bros. are a type of Hammer Bros. who, instead of throwing hammers, use boomerangs as weapons. In Super Mario Bros. 3, Boomerang Bros. appear as somewhat common enemies, especially in Desert Land, attacking Mario or Luigi by throwing multiple boomerangs at them, which always flew back to the Boomerang Bro. In order to defeat a Boomerang Bro., Mario or Luigi would need to jump on it or throw something at it, such as a fireball or shell. In Dark Land, Boomerang Bros. also appear as the captains of Bowser's tank and ship forces.

In Yoshi's Safari, Boomerang Bros. would occasionally appear as mini-bosses who would attack Mario and Yoshi by throwing boomerangs at them; the Boomerang Bros. of Yoshi's Safari are difficult adversaries to defeat, as they posses a large amount of health and run back and forth quite quickly. Also of note, in Yoshi's Safari, Mario could knock away a Boomerang Bros. thrown boomerangs by blasting them with his Super Scope.

In Mario & Luigi: Superstar Saga, Boomerang Bros., though extremely thin, tall and wearing sunglasses and sprouts on their heads, appear as enemies in Gwarhar Lagoon. In battle, these Boomerang Brothers would throw boomerangs, which Mario and Luigi would need to dodge on the boomerang's first throw and it's return. A single Boomerang Bro., named Bamma, appears in Paper Mario: The Thousand-Year Door as a competitor in the Glitz Pit; like the Boomerang Bros. in Super Mario Bros. 3, Bamma will attack Mario by either throwing a single boomerang at him or multiple ones.

In Mario Superstar Baseball, one of the alternate color schemes for the game's playable Hammer Bro. is a Boomerang Bro., who wields a large boomerang in place of a baseball bat (the same way Hammer Bro. wields a hammer in place of a bat). In New Super Mario Bros., Boomerang Bros. appear as somewhat rare enemies, however again appearing more commonly in World 2, a desert, who will attack Mario or Luigi by throwing boomerangs at them. The most recent appearance of Boomerang Bros. was in Super Paper Mario, which featured several Boomerang Bros. which had been brainwashed by Nastasia to serve under Count Bleck. Super Paper Mario also featured a new, shadowed sub-species of Boomerang Brothers known as Dark Boomerang Bros.

Anime
In the Momotarō segment of the Super Mario Amada Series, a Boomerang Bro. appears as an ally of Mario, helping him rescue Princess Peach and defeat the evil ogre Bowser.

Television
Boomerang Bros. also appeared several times in The Adventures of Super Mario Bros. 3, serving as soldiers in Bowser's army. Through the use of their boomerangs, Boomerang Bros. were practical in long range attacks. Unlike in the game, it was not uncommon for Boomerang Bros. on the show to travel together in groups.

Literature
A Boomerang Bro. made a relatively minor appearance in Nintendo Comics System issue "The Kingdom Enquirer", which had one appearing to attack Mario and Toad with it's boomerangs after the two exit a Warp Pipe.

Trivia
Originally, Boomerang Bros. were portrayed as being green in color and possessing black armor, though more recently, they have been shown to be yellow in color and either wearing bright blue or gray colored armoring. Prior to the debut of the Boomerang Bros., The Super Mario Bros. Super Show! episode "Crocodile Mario featured standard Koopa Troopas that attacked with Boomerangs.
