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. He speaks with a western Japanese accent and has long-lasting sentences just like Mojo, but the only thing different is that Mojo lives in a laboratory built on an active volcano in Townsville and Jomo lives in a laboratory just like Mojo, but his laboratory is built on a mountainous, dormant volcano in the middle of Vilestown.
