Hammer Bro is one of the Blind Bag characters in Lego Dimensions 2: The Rise of Enoch, from Nintendo's subfranchise Super Mario Bros.
Hammer Bros. (or Hammer Brothers) are recurring enemies in the Mario series. They are specialized Koopa Troopas commonly found in pairs (though not exclusively so) who wear light armor and utilize hammers as their main weapons. Hammer Bros. first appear in the later levels of Super Mario Bros.. They look similar to a Boomerang Bro. or a Fire Bro. except they have different weapons and colors of their armor, Fire Bros and Boomerang Bros being red and blue respectively.
Hammer Bros are described in various games as being the elite of Bowser's army and often appear in games either as powerful generic enemies or as boss characters. A Hammer Bros.' attack pattern consists of guarding a small area and tossing hammers at the player, occasionally moving around or jumping ; the Mario RPG games introduced a more varied attack pattern for Hammer Bros., such the ability to throw a rapid volley of hammers or throw a single hammer with enough force to literally shrink the player. Beginning with Mario Superstar Baseball, Hammer Bros. appear infrequently as playable characters in spin-off Mario games. They appear in Super Smash Bros. Brawl as Assist Trophies. In Mario Superstar Baseball, They use a Hammer as a bat. They also appear as a boss in Mario Party DS and as an unlocked playable character in Mario Party 8.
In The Super Mario Bros. Super Show! and The Adventures of Super Mario Bros. 3 by DIC Entertainment, Hammer Bros. make sparse appearances as antagonists. Printed mediums such as Nintendo Comics System and Nintendo Adventure Books make more frequent use of Hammer Bros. In the Super Mario Bros. 1993 film, a reference to the Hammer Bros. appears in the form of a tattoo parlour known as "Hammer X Bros."; the helmets worn by some of King Koopa's troops in the film are also identical to those adorned by Hammer Bros.
