Sonic the Hedgehog (character)
Personality: In the games, Knuckles is independent, headstrong, devoted to his duty and is very trusting (this leads to him being tricked by Eggman a lot). He is very serious and usually likes to be by himself, but can be relied upon to help out whenever the planet is in danger. Knuckles is extremely stubborn and is often described as a loner. Because of his flaws, he and Sonic do not always get along, but are still allies.
