is a fictional character in Sega's Sonic the Hedgehog series. He is a red anthropomorphic echidna who is determined and serious, but sometimes gullible. He has the ability to glide and climb up walls, and is a powerful fighter due to his spiked hands. He serves as the guardian of the Master Emerald, a huge gemstone that controls the series' integral Chaos Emeralds. Knuckles first debuted in Sonic the Hedgehog 3 in 1994 after Doctor Eggman tricks him into opposing Sonic and Tails. He first became playable in Sonic & Knuckles later that year; he learns of Eggman's trickery and teams up with Sonic during that game's events. Since then he has appeared in dozens of playable and non-playable roles, as well as in several series of comic books, Western animated television, and Japanese anime. Knuckles is one of the series' most popular characters, although some have voiced disapproval of the ''Sonic'' series' extensive cast of characters and singled out Knuckles as ushering them in. His likeness has frequently appeared in Sonic merchandise.
