Ice Bro

Ice Bros. are a rare species of Hammer Bro that debuted in New Super Mario Bros. Wii. Ice Bros. resemble ordinary Hammer Bros., but with light cyan/pure white shoes, shells and helmets. Instead of throwing hammers, they will throw Ice Balls at their enemies (similar to how Fire Bros. throw Fireballs, except that their ice balls disappear upon hitting the ground).

Ice Bros. appear in the World 3 Enemy Course of New Super Mario Bros. Wii. As aforementioned, they use Ice Balls as weapons to harm and freeze Mario and company into ice cubes; their ice balls can also freeze other enemies, including others of their species). Like most of their related species, they usually attack in a group of their members. If a Yoshi catches one of their Ice Balls, the Yoshi can spit it out in the form of a blue fireball that freezes anything in its path.

Ice Bros. make their Paper Mario debut in Paper Mario: Sticker Star for the Nintendo 3DS. Their appearance is the same as in New Super Mario Bros. Wii. They appear in enemies in most of World 4. They are quite a common enemy in this game, being slightly more common than Fire Bros. Like in New Super Mario Bros. Wii, they throw Ice Balls and try to hit Mario. Most of them will home in on Mario, and do 3 HP of damage and freeze Mario for a few seconds if they hit. Being frozen will also leave Mario vulnerable to a First Strike from other enemies in the area. Ice Bros later appear in the first area of Rugged Road after the player has placed an ice-based Thing sticker, which will turn all the Fire Bros. in the area into Ice Bros.

In battle, they are immune to all Ice Flower Stickers and Chillhammer stickers. Their main weakness is fire; if the player uses a Fire Flower or a Burnhammer sticker, they take double damage.
