Knuckles coloring pages.
Knuckles the Echidna is a character from the Sonic the Hedgehog series. He is an anthropomorphic echidna and the current guardian of the Master Emerald, a powerful ancient gemstone kept on Angel Island. Guarding it is his solemn duty to protect against anyone who would abuse it, as well as the only surviving descendant of the Knuckles Clan's echidna race. Known for his powerful and wild nature, his dominant traits are his super strength and the two pointed knuckles on each of his gloves, from which his name is derived, and which allow him to dig and climb walls. He can also catch the wind under his dreadlocks to glide through the air. Knuckles is also one of Sonic the Hedgehog's oldest friends and rivals.
