- For the version of this group before the Super Genesis Wave, see Knuckles Clan (Pre-Super Genesis Wave).
The Knuckles Clan is a group that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It was a race of echidnas that lived thousands years ago in what would become the Mystic Ruins, and the ancestors of Knuckles the Echidna. After an era of bloody war efforts, the clan was virtually wiped out when they incurred the wrath of Chaos. Though remnants of the clan remained, most of them would die out in the centuries that followed.
The Knuckles Clan once lived in an area of Sonic's World near the home of Chaos, who protected the Master Emerald and Chaos Emeralds and the Chao Garden in which they were found. For a time, the clan lived peacefully with its neighbors, but the warmongering chief Pachacamac sought to seize more land for his people and led them into war. In a bid to give him the strength to destroy any opposition, he and his men attacked Chaos' home and the Chao living there, despite the attempts of Pachacamac's daughter, Tikal, to stop them.
Their actions enraged Chaos, who destroyed most of the Knuckles Clan before being sealed away in the Master Emerald by, and with, Tikal. These events resulted in the creation of Angel Island, with the remnants of the Knuckles Clan civilization appearing either there or on the surface as the Mystic Ruins. Tikal would become a spirit, and the clan's actions resulted in the race declining until only one surviving member was known to exist: Knuckles.
