Saur was given to Red when he accidentally released all of Professor Oak's Pokémon from his lab. After Red caught back all of his Pokémon, Red battled Saur with his Poli and caught him. Professor Oak saw the bonding between Saur and Red, as well as the fact that Saur learned how to use SolarBeam, and allowed him to keep it. It evolved into Ivysaur in PS015 at the gates of Celadon City, when it battled an attacking Primeape. Saur was temporarily under Green's ownership by accident when Red and Green's Poké Balls were swapped. It evolved again in PS033, when he was battling the merged version of Zapdos, Moltres, and Articuno. Red told Saur to keep attacking when he evolved. At the Pokémon League, it was the first Pokémon he sent out against Green. In the end, along with Poli and Pika, it was able to defeat Green's Charizard. In the Sevii Islands, Saur learned the move exclusive to the Grass-type starter families, Frenzy Plant.
