From Bulbapedia, the community-driven Pokémon encyclopedia.
Silver is the rival of Gold and Kris, and is about their age. He has long red hair and piercing eyes.
Fan speculation is that Silver may be Giovanni's red-haired child, due to Pokémon FireRed and LeafGreen's Fame Checker's many references to Pokémon Gold and Silver versions, and to Silver's dark demeanor and detestment of Team Rocket.
In the anime
Like Brendan, he played no role in the anime, despite being a main character in the games. Similarly, his only appearance in anime is a brief cameo, in the original Japanese opening of The Legend of Thunder (A New Oath), where he was shown with his Nidoking defeating Jimmy.
In the game
Silver's first (and currently only) appearance in the Pokémon video games took place during Generation II. He was first seen lurking near a window to the Elm Pokémon Laboratory; he later broke in, stealing a Pokémon (the Pokémon that is strongest against the player's chosen starter). He later used this Pokémon to battle Gold/Kris, doing this many times as they journeyed through Johto. This is not the only Pokémon he has stolen, as he also stole a Sneasel from a man in Cianwood City.
Throughout his travels, Silver showed a strong hate for Team Rocket. He strongly interfered with the revived Team Rocket's plans at least twice, including their experiments with radio signals at the Lake of Rage. His stated reason for this dislike was that they are "weak" when cornered, and that he only cares about strong opponents. During one of his missions against Team Rocket, Silver apparently fought against Lance, who utterly decimated him. Silver is soon frustrated, as he claims that Lance told him he doesn't love his Pokémon enough. Lance's words are Silver's catalyst, as he begins to metamorphisize into a more kind hearted person. Before a battle at Mount Moon, Silver claims that he has reached his peak, finally understanding what Lance told him in Mahogany Town. During this battle, he uses a Crobat, displaying that he now truly does care for his Pokémon.
Shortly after Gold/Kris defeated the Pokémon League, Silver took up training in the Dragon's Den. His personality has been likened by the Dragon Master to be similar to Clair's. He can be seen there on Tuesdays on Thursdays, and can be challenged at the Pokémon League on Mondays and Wednesdays. His activities on the weekend are unknown, but now that he is a kinder person, it can be assumed that he does not train on these days.
The starter Pokémon that Silver has will depend on which Pokémon the player chose to bring on Professor Elm's errand at the beginning of the game. As with all rivals, it will be the Pokémon whose type weakens that of the player's starter.
At some specific days in the PokéGear, Silver will challenge the player just when the latter is ready to face the Elite Four in the Indigo Plateau.
Silver is the player's final opponent in the game, after completing every other battle. After his defeat, players will move on to Round 2, where all of the battles are much harder, or have beaten the entirety of the game. He is named just "Rival" in this game.
Silver has the following Pokémon in this game:
- Pearl also can be battled again (on Saturdays and Sundays) after the player becomes champion. He can also be found training at Stark Mountain during the week. This may be a reference to Silver's training schedule.
- If Silver's stolen starter is Totodile, he uses Croconaw at level 16 in his second battle, despite that Pokémon being obtainable only from level 18 onwards. However, if Silver's stolen starter is Cyndaquil, he uses Quilava at level 32 in his sixth battle, by which point the other starters have evolved.
