I'll probably be on this floating island forever. Guarding the Master Emerald, again. I may not know the whole story behind this. But perhaps it's better that way.
~ Knuckles the Echidna, Sonic Adventure
Knuckles the Echidna is a character from the Sonic the Hedgehog series. He appeared in the 51st episode of DEATH BATTLE!, Donkey Kong VS Knuckles, where he fought against Donkey Kong from the video game series of the same name and Super Mario series.


The sole Echidna on Earth, Knuckles is the protector of the Master Emerald on Angel Island. He rarely leaves the island unless something big happens to the emerald or somewhere else.

He first met Dr. Eggman, and was told by him that Sonic was after the Master Emerald, and he needed his help. Not knowing that this was a lie, Knuckles fought against Sonic, but was soon able to realize his mistake and turned his attention to Eggman and helped defeat him. Knuckles would later become a strong ally to Sonic and his friends in later adventures.
