Knuckles the Echidna

Knuckles is a wild and tough echidna. He is stubborn and doesn't adapt easily. Once he and Sonic were rivals, but their differences have been resolved. He is often jealous of Sonic's free spirit (Rouge once stated that Knuckles had an "inferiority complex") He is famous as a treasure hunter and a master of martial arts. His arms are so powerful that he can shatter rocks. Ever since the big Chaos Control, Knuckles has become dedicated to finding the Chaos Emeralds so he can go back to his job of guarding theMaster Emerald.
