Like Brendan, Lucas and Ethan (excluding Jimmy), he played no role in the anime, despite being a main character in the games. Similarly, his only appearance in the anime is a brief cameo, in the original Japanese opening of The Legend of Thunder! (A New Oath), where he was shown defeating Jimmy with his Nidoking, only to be defeated later on when Jimmy's Cyndaquil evolves into Typhlosion.
While Silver did not appear in the main series of the anime, he was considered by much of the fandom to have a close counterpart in the character of Paul, who was Ash's main rival throughout the Diamond & Pearl series. Like Silver, Paul believed in raising the power of his Pokémon through harsh training as opposed to forming a trusting relationship which put him at odds with Ash throughout the series. Also, Paul's official art shows him in the same pose as Silver does in one of his official artwork by Ken Sugimori.
