Like Mojo, he has a large brain with a helmet and creates machines, though for the good of mankind rather than for its destruction. Jomo has yellow skin, black fur, orange eyes, a large, overly exposed brain under his helmet, which has straight green stripes, light greenish gloves and boots, an orange necklace with the letter J on it, a light greenish belt with a diamond on it. Somehow Jomo's legs are furless but in the rest of the series they are covered with a thick layer of hairy black fur.
