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.KEL appears to share a strong bond with his brother HERO and occasionally bickers with AUBREY over petty disagreements over minor topics. He even sees the quiet SUNNY as someone who is a great person and believes the best in him. These traits are shared with his HEADSPACE counterpart.
