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 blue/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).

New Super Mario Bros. Wii
Ice Bros. appear in World 3 of New Super Mario Bros. Wii. They are the enemies in the Enemy Course. As aforementioned, they use Ice Balls as weapons to harm and freeze a playable character into an ice cube (even freezing 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.

New Super Mario Bros. U
Ice Bros. reappear in New Super Mario Bros. U, where they are found in Frosted Glacier, Icicle Caverns in which there are only 2 of them and. They behave the same way they did in New Super Mario Bros. Wii, where they attempt to freeze a playable character by throwing Ice Balls.

New Super Luigi U
In New Super Luigi U, Ice Bros. are slightly more common. They appear in the levels All Aboard! and Frozen Fuzzies.

Paper Mario: Sticker Star
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 are usually enemies in most of World 4. They are quite a common enemy in this game, being slighty more common than Fire Bros. Like in New Super Mario Bros. Wii, they throw Ice Balls and try to hit Mario. The Ice Balls can freeze Mario for a few seconds and most of the Ice Bros. ice balls will home in on Mario. 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. They later appear in the first area of Rugged Road after the player has placed an ice based thing sticker (Which made the Fire Bros. inhabiting the area Ice Bros.). This game may prove that Ice Bros. are, in fact, Fire Bros. Mario will lose 3 HP if he is hit by an Ice Bros. ice ball. Also in Whiteout Valley outside battle, if the player has froze into an ice cube and an enemy such as a Fuzzy or a Shiny Paragoomba hits Mario while he is frozen, Mario will get hurt since the enemy will attack first.

Paper Mario: Color Splash
Ice Bros. reappear in Paper Mario: Color Splash, behaving the same way as in the predecessor.

They can be found in Lighthouse Island, Fortune Island and Black Bowser's Castle. A large number of them appear behind the waterfall in the parallel world of Lighthouse Island.

An Ice Bro appears in Redpepper Volcano, where he tries to persuade his coach, a Snifit, to let him fight Mario after all of the Fire Bros. are defeated. When he tries to throw an ice ball at Mario, he misses and hits the ground in front of him.

Mario Golf: World Tour
In Mario Golf: World Tour, one of the names that can appear on the tournament scoreboard is "Ice Bro".

Puzzle & Dragons: Super Mario Bros. Edition
Ice Bros appear in Puzzle & Dragons: Super Mario Bros. Edition as Water-attribute enemies. In battle, in addition to attacking normally, they may occasionally use Water Change to cause damage and change any Fire Orbs on the player's Orb field into Water Orbs, as well as Frenzied Blows to deal a large amount of damage. When defeated, they may randomly drop Light Blocks of Hammer Bros, while defeating them with 10+ Combo attacks guarantees they will drop Ice Flowers. As Water enemies, they take extra damage from Wood attribute attacks and less from Fire damage.

As teammates, Ice Bros have an HP rating of 4/6, an ATK rating of 5/6, and a RCV rating of 2/6. Their Water Change Skill is identical to when used as enemies, and their Awoken Skill Recovery Boost increases HP healed when clearing Heart Orbs. Ice Bros use Star Coins and Grand Star Coins to raise their Skill Levels. The player can create an Ice Bro by transforming a Hammer Bro with five Ice Flowers. Teammates may occasionally gain ATK pluses from depowered Ice Bros.

Mario & Luigi: Superstar Saga + Bowser's Minions
Ice Bros reappear in Mario & Luigi: Superstar Saga + Bowser's Minions after being absent from the original game. They appear as enemies and recruitable Ranged-type allies exclusively in Minion Quest: The Search for Bowser, and are first encountered in Ice Guys Finish Last. They are weak against Fly Guys.
