Knuckles-Zilla is a giant, evil version of Knuckles the Echidna. He has red eyes, fangs for teeth, and his fur color is much more of a darker, dull red. He has a spike on his arm, and his dreadlocks resemble a squid's tentacles.
In this universe, Chaos Emerald radiation transformed Knuckles into a hideous, gigantic monster that threatened the people of Mayor Kintobor's city. Despite his fearsome mutations, he was unable to stop the Giant Robotno piloted by Sonic the Hedgehog. (SSS: #12)
