Silver

Silver is the rival of Gold in Gen II and also the son of Giovanni the leader of Team Rocket. At the beginning of the game Silver breaks into Professor Elm's lab and steals a starter Pokemon, which is the super effective type against your starter Pokemon. For example: If you choose Totodile he will choose Chikorita, ff you choose Cyndaquil he will choose Totodile, and if you choose Chikorita he will choose Cyndaquil. Silver challenges you to a battle at the entrance to CherryGrove City, and after you defeat him, a policeman will come and ask for his name. This is the place where you will name him. He continues to appear and challenges you throughout the game in various places in Johto and Kanto.
