He's the ideological opposite of Ash and constantly defeated him in battle which is part of why Ash has a lower winrate in Sinnoh compared to other regions. Other rivals don't have much, Gary is just a bully and his first fight with Ash was at the end of Kanto, Ritchie was a samefag and his win wasn't earned at all, Trip was just a lesser version of him and his final fight was just a 1v1, Alain and Gladion don't have anything against Ash, they were just guys Ash had to battle for the championship.
