Knuckles the Echidna

ナックルズ・ザ・エキドゥナ

As the sole survivor of his clan, Knuckles spent most of his life in isolation on Angel Island, a floating landmass, which has made him something of a loner. His lack of experience with outsiders renders him both very honest and gullible. Knuckles is shy around girls. Although he is cool and determined in battle, his short temper leads to situations where Knuckles, often provoked by Dr. Eggman's trickery, begins fighting Sonic the Hedgehog. In the anime Sonic X, when Amy asks Sonic why Knuckles wouldn't join them, Sonic replies, "That's Knuckles. He does things his own way." Although he and Sonic fight from time to time, there is an undercurrent of mutual understanding between the two. Ever since the introduction of Shadow the Hedgehog as one of Sonic's darker, more anti-heroic rivals, Knuckles' relationship with Sonic has appeared much friendlier by comparison, and they both rarely fight anymore. Additionally, Knuckles has been tasked all his life with being the Guardian of the Master Emerald, as only descendants of his tribe are capable of controlling it. If Sonic exemplifies the wind, then Knuckles is the mountain: stern and anchored to his duty. However, he finds Sonic's adventurous lifestyle enviable. Various literature from the early games lists his favorite food as fruit, or to be more specific, grapes. He is also described as hating strong light; in Casino Park in Sonic Heroes, if you keep the characters still for long enough, he'll say, "Everything is so twinkling and bright. I hate it!!"
