Knuckles the Echidna (voiced by Brian Drummond) - He is 16 year old. Sonic's friendly rival. First introduced in the Genesis game Sonic the Hedgehog 3, Knuckles lives on Angel Island, which hovers in the sky due to the power of the Master Emerald. As the last surviving member of the Echidna people who once inhabited the island, his duty is to guard the master Emerald.
Knuckles the Echidna was said to appear in the third season of the series, but it was canceled. Thanks a lot, ABC, voice by Brian Drummond.
