Winterhorn

The Winterhorn is an Emblem Heartless that appears in Kingdom Hearts III.

Kingdom Hearts III
After other Heartless were slain by Sora, Donald, and Goofy to defend Queen Elsa, a Winterhorn attempts a sneak attack from above. However, Elsa manages to destroy it with a blast of ice magic.

Design
A Winterhorn Heartless takes in a form of a small reindeer buck. It has a largely blue and black body with a Heartless emblem in its front. It has a sharply curled black tail, a saddle on its back, and bent legs with icy hooves. On its head are a pair of large icy antlers, and its black face contains two yellow eyes and a blue snout.

The name derives from its antlers, which are wrought of crystal ice.

Strategy
Winterhorns will usually try to keep distance before attacking, so look out for their attacks when at a distance. Its Air Assault attack can be blocked from behind, so using Dodge Roll isn't necessary. They typically appear in packs, so it may be safer to block one of its attacks and go for a reprisal where it will be knocked back from its allies and defeated quickly than to charge in with physical combos where another one of the Winterhorns can potentially interrupt. If they're close enough together and enough MP is available, using Thunder or Aero magic is an option as well.

Winterhorns have a massive weakness to Fire magic, as not only do they take extra damage from it, but being hit by a Fire attack will cause their antlers to break, which greatly reduces their offensive capabilities. Their antlers will regrow after 30-40 seconds or if struck by a Blizzard attack.
