Luke is sporty, and active in school. Initially seeming like a bully, Luke is shown to be actually kind and friendly, making attempts to befriend Eugene and even swearing to protect them from bullies after they helped him with his nightmares. As a pet owner, he is very affectionate and often babied his cat Kitty-- a stark difference from his cool persona at school.He is Eugene's classmate and eventual best friend(i ship them).
