Lysandre's Pyroar was first seen battling against
Alain while he was searching for a Denryunite in some ruins and
Lysandre challenged him to a battle where
Alain could claim the stone if he won the battle. Alan lost the battle.
It was seen once again when it broke up a battle between
Alain and
Steven Stone.
Its only battle in the anime was against
Alain and
Ash Ketchum on top of the Prism Tower. It was attacked by both of them and was knocked out leaving
Lysandre's Gyarados (Shiny) on its own to fight the battle.
