Hasbro Pokemon Thinkchip Battle Stadium allows you to have Pokemon battles with up to six THINKChip™ Pokémon™ Figures per trainer. You can evolve your Pokemon during battle to give them more Hit Points and allow them to last longer. You can also retreat your Pokemon to replace them with a different one, either to gain the "type" advantage over your opponent or to bring out a Pokemon with a higher Hit Point Level. The stadium's lights and sound effects will guide you through the battle, and the Attack Point Chart will help you determine how much damage your attacks do.
