 He has a long beard for a time (which he grew in an attempt to impress Tenma), a shaved head shortly following him shaving his beard off, and because Eri was mad at him for that she shaved the top of his head, and for a time has a shaved face because Eri accidentally cut it, and upon hearing that Tenma didn't like beards he shaved it off completely.Eventually he returns to the look the series started with.He also has his own finisher attack, named 'Hurricane Kick' (a portmanteau of his name, HARIma KENji) which parodies Kamen Rider's Rider Kick.
