Jack has long red hair and red eyes. His werewolf form has white fur.
Jack is very charismatic and eccentric, as well as quite flirtatious.
When Queen Adelina and King Camillo arrive to the Halloween Kingdom, Jack and his subjects greet them with a musical number, but he soon realizes the seriousness of the vampires' threat. Jack takes them to the castle and shows them the four Joyful Heart Stones that appeared in the kingdom three days prior.
