During his youth, KEL is a bit bratty, impulsive and rude, always getting into little tiffs with his friends. He is very competitive by nature, always wanting to win games or races, and is indeed very energetic and fast. He also thinks romance is gross and that girls have cooties. However, even though he is loud and likes to annoy his friends, he genuinely cares about them to the point of constantly protecting them with a strong sense of justice.
