Gradient Joe is the most humanlike in the group, with the only non-human feature being a sphere with a radial gradient for his head. He wears basic clothing, grey-ish pants with a collared(?) shirt and striped, navy tie. Not much is known about his personality, since he doesn’t like to speak. According to Bugbo, he is very clever. Instead of talking, he would mainly communicate by writing on pieces of paper with a red marker. He also tends to express himself emotionally by his head.
