Dennis is a wild, stubborn tsundere who finds joy in causing chaos + mayhem due to his hatred of rules + order. Dennis is sometimes selfish. His misbehaviour stems from an attempt to add excitement to a dull day. Dennis is fairly stupid, but he's good at mechanics. He is a 14 y/o boy who has scruffy black hair. He wears a red + black jumper, grey shorts + black trainers. He has a crush on his Rival, Walter, despite never getting along with him. His catchphrase is blam, meaning awesome.
