Freezard

Freezards, originally spelled Freezzards, are enemy creatures made of living ice capable of spewing freezing cold breath. Due to their nature, they are almost exclusively found in extremely cold areas and have a weakness to heat. Their name is likely a combination of "freeze" (or "freezer") and "blizzard."

The Legend of Zelda: Ocarina of Time
In The Legend of Zelda: Ocarina of Time, Freezzards are unique to the Ice Cavern, though in Master Quest, they are added to the "water" portion of Ganon's Castle. They resemble jagged ice sculptures vaguely shaped like a tall, horned head around adult Link's height, and shoot their icy breath from a hole on their lower half that seems to be a mouth. Some stay still, shooting cold air periodically, while others fade into existence and follow after Link, sometimes fading away to reappear elsewhere. Repeated sword strikes will gradually chip them away until they are defeated, and they can be melted instantly with Din's Fire and Fire Arrows, the latter of which can only be obtained after the Ice Cavern is completed. Unlike most enemies, hitting them with the hookshot brings Link right to them. In Ocarina of Time 3D, the original "Freezzard" spelling is changed to the "Freezard" spelling used in other games.

The Legend of Zelda: Majora' Mask
In The Legend of Zelda: Majora' Mask, only the motionless type of Freezard appears. Three appear along the sides of a bridge Goron Link needs to roll across in the Snowhead Temple, while others appear in small rooms beneath the Well. When defeated, they normally give arrows, but sometimes also give large magic jars.

The Legend of Zelda: Twilight Princess
In The Legend of Zelda: Twilight Princess, Freezards are found in the Peak Province, namely Snowpeak Ruins and in dig caverns. Additionally, they are found on certain icy floors of the Cave of Ordeals. Freezards in this game are massive and resemble multi-eyed dragons. They cannot move around, though they can pivot to face Link. They spend several seconds inhaling before breathing out a large continuous gust, and can turn at any point in the process. Additionally, their bodies are surrounded by an icy aura that freezes Link on contact. Initially to defeat them, Link must use a specifically placed cannon, though once he gains the Ball and Chain, he can defeat them through repeated hits from it. Once a Freezard is defeated, it splits into numerous Mini Freezards.

The Legend of Zelda: Tri Force Heroes
In The Legend of Zelda: Tri Force Heroes, Freezards are back to their original size and general shape, though their features are now much more clearly defined into a face. They are immobile and cannot turn, and as such they function more as an obstacle than a typical enemy. They often block paths with an endless stream of icy breath, and must be melted through careful use of fireballs from the Fire Gloves. They primarily appear in the Ice Cavern, but also appear in an ice-themed portion of the Sky Temple and in the Frozen Zone of the Den of Trials. In these locations, it can be seen that other sub-weapons can defeat them as well, but take more hits. Additionally, the miniboss of the Ice Cavern is a giant Freezard named Freezlord.
