Frostbite

Frostbite is a Yeti-like ghost in charge of the Realm of the Far Frozen. Frostbite and his race, despite their fearsome appearances, are intelligent creatures capable of many things, including medicine and technology. They refer to Danny as "Great One" and "The Savior of the Ghost Zone" and treat him like a king due to his defeat of Pariah Dark[1]; Frostbite even introduces himself to Danny as his "humble servant."
