Jules-Zilla is a giant, non-robotic form of Jules Hedgehog. He has a Chaos Emerald embedded in his chest and has the same form as the non-robotic Jules. He has fangs for teeth, red eyes and a more violent personality.
In this universe, Chaos Emerald radiation transformed Jules into a hideous, gigantic monster. When Sonic the Hedgehog in Giant Robotno traveled to Knothole Island to get two split halves of a Chaos Emerald, he found one of the Emerald halves embedded in Jules-Zilla's chest. During the fight, Sonic accidentally ripped the Emerald half from Jules-Zilla, killing him in the process. After an anguished Sonic left with half an Emerald, Sonic-Zilla, with the other Emerald half in his chest, cried at his dead father's body. (SSS: #12)
