Knuckles the Echidna

Knuckles the Echidna (ナックルズ・ザ・エキドゥナ Nakkurusu za Ekiduna?)   is a fictional character from the   Sonic the Hedgehogseries. He is an anthropomorphic   echidna  and the current guardian of the   Master Emerald, a powerful ancient relic which is his solemn duty to protect from anyone who wants to abuse it. He is also the sole remaining descendant of the   Knuckles Clan  and last of the echidnas on   earth. His dominant traits are his superhuman strength, and the two spike-like knuckles on each of his hands, from which his name is derived from, which he can use to dig with and climb up walls. He can also trap the wind under his dreadlocks to glide through the air.

He is fully devoted to his duty, spending most of his time on Angel Island protecting the Master Emerald, and rarely cares for anything that is not important. When his friends and others are in need of his help, however, Knuckles can always be relied on being willing to leave his post and prove himself a true and good-hearted hero. He is also one ofSonic's oldest friends and rivals.
