Jak, originally Mar, is the son of the deceased former king of Spargus City, Damas. Sent to the past as a little boy, he was raised by the sage of Green Eco named Samos Hagai. He grew up in Sandover Village with Samos' daughter Keira and his best friend Daxter but was mute for his first 15 years. After he, Daxter, Keira and Samos arrived in the future of Haven City, he was captured and experimented on with Dark Eco for two years. He's now become a hero and he's ready to race against the best.
