He first appeared in the episode "Infinite Realms" when Danny, Sam and Tucker crash land in his icy domain. At first, Frostbite attacked Danny due to a painful icicle embedded in his fur. Once Danny noticed this and zapped it free, Frostbite's pleasant and formal demeanor returned. Frostbite was honored that his rescuer was none other than Danny Phantom, the "Savior of the Ghost Zone." Frostbite and his people treated Danny as a king. Danny accepted the praise and the help offered by Frostbite, although he remained confused of its origin. As the people of the Far Frozen repaired the damaged Specter Speeder, Frostbite showed Danny and his friends around. After reaching a cave, Frostbite proceeded to explain to Danny and his friends that Danny's fame had been spreading all around the Ghost Zone since Danny imprisoned the Ghost King, Pariah Dark. The cave walls were covered in primitive carvings of Danny, honoring his triumph over Dark. Frostbite bestows Danny with the Infi-map which can take its user to any natural or man-made ghost portal. After the events of the episode, Danny returns to the realm of the Far Frozen to discover from Frostbite that the Infi-map doesn't always take users where they want to go, but where the map itself feels they must go. Danny thanks Frostbite again for his help and wisdom. Frostbite then states to another clan member that the "Great One" will return. He has more in common with the Far Frozen than he realizes.
In “Urban Jungle,” when Danny comes down with a case of unusual chills (a precursor to his emerging ice powers) while fighting Undergrowth, he comes to Frostbite for help. Having treated Danny's injuries, Frostbite subsequently trains Danny in the use of his new ice powers while his people watch (The explanation being that, with them living in a frozen wasteland, his people take their entertainment where they can get it). He subsequently wishes Danny luck in ridding his world of Undergrowth, although his people are less than enthusiastic about Danny returning if he is unsuccessful (He froze and nearly injured several of them while working on the "aiming" part of his new powers).
He later makes a cameo appearance in “Phantom Planet” as one of the ghosts who helps turn the Earth intangible. Vlad has the Infi-map implying that Vlad defeated him.
- Ghost Powers: Since he is a ghost, he has all the basic ghost powers: invisibility, intangibility, and flight.
- Cryokinesis: Frostbite is extremely proficient in this power and is seen freezing people solid. He can also fire freeze blasts from his eyes and hands and shot ice spikes from his hands. His ice powers even allows him to freeze Danny's ghost rays.
- Ice Constructs: His mastery on his ice powers allows him to create ice objects, such like snow balls, ice diamonds, statues and ice swords. He can also manipulate his icy constructs to turn them into something else.
- Superhuman Strength: He is strong enough to lift and carry the Specter speeder (with Sam and Tucker inside of it) and Danny at the same time with no physical strain at all.
- Superhuman Endurance: He is able to take one ghost ray from Danny without further damage.
