New Super Mario Bros.
Although the basic Hammer Bro. was absent again from "Super Mario World", two new subspecies were added, the Amazing Flyin' Hammer Brother, and the Sumo Brother (later known as the Sumo Bro.), both of which would later appear in "New Super Mario Bros.", "New Super Mario Bros. Wii" (which introduced the Ice Bro., a cold-weather counterpart to the Fire Bro.), "Super Mario Galaxy 2" (the first time that the Hammer Bro. appeared in a 3D "Mario" game), "Super Mario 3D Land", "Super Mario World", "New Super Mario Bros. 2", "New Super Mario Bros. U". They reappeared in "Super Mario Odyssey", where Mario can use their powers for the first time in 3D and on "Super Mario Maker"/"Super Mario Maker 2".
