Knucknick the Hedgehog

Knucknick the Hedgehog, or Nick, is an anthropomorphic 17 year old cyan hedgehog with overgrown knuckles, just like Knuckles the Echinda. Nick is also Knuckles's partner by guarding the Master Emerald, even though Nick is not part of the Echinda Tribe. His only appearance so far was Sonic the Hedgehog.
