Gold and Silver series
Silver sent Tyranitar to battle Gold. Tyranitar was too powerful for Silver to handle, as he let Tyranitar use Sandstorm on Gold and his Pokémon. Gold had Polibo fire Water Gun on Tyranitar, but Silver had Murkrow take the hit. However, Gold's Togebo used Double-Edge, which knocked Tyranitar out. Togebo was defeated as well, but Silver was astounded Gold managed to defeat Tyranitar. With the battle over, Silver called his Pokémon back.
Lance sent Tyranitar at the Ruins of Alph to defend him from intruders. As Gold arrived, Tyranitar went to attack, but Lance stopped it, as Gold was not the enemy.
