White Wolfos

The White Wolfos, as the name describes, are snowy, sometimes anthropomorphic wolf-like enemies that appear in, Majora's Mask, Twilight Princess and Spirit Tracks.

Characteristics
White Wolfos generally take to icy climates such as the Snow Realm in Spirit Tracks and Snowpeak in Twilight Princess, however, these foes have been spotted in unlikely areas as well such as the Gerudo's Training Ground in Ocarina of Time. These creatures are usually common overworld enemies, though in Majora's Mask, they disappear in Snowhead and the surrounding area once Goht is defeated, and only one White Wolfos appears in the Ice Cavern of Ocarina of Time as a mini-boss. In terms of appearance, the Twilight Princess incarnation inhibits a glow of sorts, adding to its enhanced realistic look, while the Spirit Tracks foes appear more cartoony to match the graphical style. It is interesting to note that these White Wolfos have yellow eyes, while their previous incarnations have red eyes.

These enemies tend to circle around Link, as if a human combatant themselves, looking for an appropriate time to strike and keeping their dark paws up as shields until the right moment. White Wolfos can dodge, block, and even counter Link's attacks, making them quite the formidable foe. The enemies seen in Ocarina of Time and Majora's Mask stand on their two feet while attacking, while the hounds from Twilight Princess and Spirit Tracks not only attack in packs, but choose to butt into Link on all fours, by comparison. Interestingly, the White Wolfos of Twilight Princess can dive headlong into the snow as if it was water and reappear elsewhere, enabling them to disappear at will and launch surprise attacks.

As to be expected, these creatures are close relatives of the smaller Wolfos, a similar enemy that boasts a tattered, darker coat, and identical behavior.

Weaknesses
In Ocarina of Time and Majora's Mask, Wolfos in general have a major weak spot: their tails. The easiest way to defeat one is simply to dodge its attack and strike its tail when it exposes its back, which will kill it instantly. In Twilight Princess and Spirit Tracks, because these wolves attack in groups, any conventional weapon works to dispel them.

Trivia

 * White Wolfos act similarly to real wolves. In Twilight Princess, they usually tend to retreat and regroup when they fail to harm Link.
 * Despite the names implying that the Wolfos is the default form or a more basic enemy than the White Wolfos, the White Wolfos is more common, appearing in four games to the Wolfos' two.
