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.
A loner by nature, Knuckles is independent, headstrong and serious, yet gullible and short-tempered to a fault. 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 of Sonic's oldest friends and rivals.
