Amazing Flyin' Hammer Brother

An Amazing Flyin' Hammer Brother (alternatively with "Flyin'" correctly spelled as "Flying" ), also shortened A. F. H. Bro, is a special variety of Hammer Bro found in Super Mario World and its reissues. An Amazing Flyin' Hammer Brother hovers around on a platform composed of two gray Rotating Blocks with a wing on each side that swings back and forth. This enemy tosses hammers from his swooping platform, attempting to attack Mario. He can be defeated by hitting him from below, from the side with a projectile attack, or on top. Their parent species, Hammer Bros., do not appear in the game at all.

When the Amazing Flyin' Hammer Brother is defeated, the flying platform remains and continues on its original flight path, allowing for an extra platform on which to stand; however, if the platform's rider is defeated before the platform itself begins to move, it will not have a set path and instead stays in place. In the game's credits, an Amazing Flyin' Hammer Brother appears, yet the gray Rotating Blocks are replaced with gray Empty Blocks.

One Amazing Flyin' Hammer Brother appears in the Nintendo Adventure Book Dinosaur Dilemma, capturing the remaining dinosaurs in Dinosaur Island while they, Mario and Yoshi are looking for food near Lake Trilobite. The Amazing Flyin' Hammer Brother threatens to capture Yoshi as well, but is scared off by Mario.

Amazing Flyin' Hammer Brothers make a reappearance in Super Princess Peach. A sleeping "Calm" variation called a C. A. F. H. Bro also shows up. Strangely, Peach can instantly defeat the enemy by simply touching it if it is close enough to the ground.

An Amazing Flyin' Hammer Brother makes a cameo in a Super Mario World screenshot in the original version of Nintendo Monopoly.
