Stadium 2 has an interesting choice for a final boss. When you defeat the Gym Leader Castle and all of the Stadium Cups, the option to fight against Silver, the rival from Pokémon Gold and Silver, becomes available. His team consists of Lugia, Ho-oh, and Mewtwo. At first, it seems ridiculous. That is, until you remember what kind of person Silver is. This PokéDarwinist only cares about the strongest 'Mons. He's that one friend who always stuffs his team with Legendaries in all of his Link Battles.
