Tyrantrum stood on solid air, created by Mr. Mime's power, which was advised by Ramos to Valerie. However, Bryony sent Bisharp, who attacked Mr. Mime, causing it to lose the focus and drop Tyrantrum and other Pokémon down, who could not fly nor levitate.
After the battle was over, Grant sent Tyrantrum and Aurorus to help rescue people and Pokémon that were affected by the Ultimate Weapon's blast.
None of Tyrantrum's moves are known.
