Knuckles the Echidna is a character that debuted in the game “Sonic 3 & Knuckles. He is, undoubtably, a very stubborn and gullible person. Given that he’s spent his whole life on Angel Island, he doesn’t know to much of the outside world. His anger can overtake his sense of reason and thought, but his actions are always backed up with his strong sense of justice and what’s right. He’s reliable, gets the job done, and is a good pal to Sonic and Tails.
