Jammer is a simple looking gootraxian. He looks like a wolf, with two unusually large triangular ears, bipedal, and with light blue eyes. He also has a headphone on his head which somehow lets him listen to music, despite his ears' location. The rest of his body doesnt have any special features, his body is completely covered by a grey fur which is slightly lighter on the front of his body. His body radiates a light blue-ish light in dark environments, including during blackouts.
