Knuckles, Sonic: A Hedgehog in Time

Knuckles the Echidna, also known simply as Knuckles or even Knux, is a friend and rival of Sonic the Hedgehog, as well as a past enemy. Knuckles is often portrayed as a loner, and doesn't work with many people unless it is absolutely necessary.

Knuckles lives and was born on Angel Island, which hovers in the sky due to the power of the Master Emerald. He is the last surviving member of the Echidna people who guarded this emerald; thus, it is his duty to protect it from getting into the wrong hands.
