Saur/History/FireRed & LeafGreen Chapter

In the Sevii Islands during My, My, My Mimic, Saur learned the move exclusive to the starter families, Frenzy Plant, after training on Ultima's Jump Path, Catch Path, and Battle Path courses. Afterwards, the two boys' inability to perfect their respective move's accuracy would come to haunt them in the battle against Sird, Carr, and Orm. When appeared, Saur nearly died shielding Red from the fearsome Pokémon's Psycho Boost attack.

Saur still managed to gather the strength to fight and participated in the battle on Trainer Tower in Meet Deoxys, and Deoxys, and Deoxys, and... against Deoxys' clones. Saur then agreed to be traded to Blue again to allow Red to Fly on Charizard and defeat the evil leader. After Giovanni's defeat, Saur was traded back to his original owner, but the two soon found themselves petrified by Sird with the four other Pokédex Holders and their Pokémon.
