Jack currently has white hair, striking blue eyes, and pale skin. He has a tall stature, albeit slim. He wears a blue hooded sweater, frost collecting around the ring of the collar, trousers bound with lighter material starting from the knee down to the rather tattered and frayed bottom, and is barefoot throughout the movie.
He carries around a magical staff with a G-shaped tip, resembling a shepherd's crook. It is Jack's gateway to help him unleash his powers of conjuring snow, ice, and frost.
Before Jack became immortal, he was seen wearing a brown cloak, a white woolen shirt, and a small and brown open vest. He wore the same pants as seen in the present. He had warm brown hair and dark amber eyes, rather blushed cheeks and less paler skin.
Jack is currently over 300 years old.
William Joyce has stated that Jack Frost is stuck at age of 14 but on the Rise of the Guardians App, it states: "Jack Frost has been around for over 300 years, but he is forever trapped at the age of 17."Tutorials:Commission by *xMidnightStar.
