He's human with fair skin, blue eyes, and a strong build. Green hair fading into a bright yellow at the end, green eyebrows.  He uses a cane with a large green gem in the middle, and has a leather satchel with a blue-collared sleeveless tunic, a leather belt, beige pants, and cloth strappings around his wrists, ankles and feet. He cannot speak at all except for small noises. A brave yet troubled hero chosen by the Precursors, Jak's unique skills, particularly his mastery of all eco.
