This Pidgeot is a normal/flying-type Pokémon owned by Falkner. It was the last Pokémon Falkner sent out in his gym battle with Ash.
When Team Rocket attacked his glider, Falkner sent Pidgeot to save him, then had it pierce Team Rocket's balloon. Falkner came down and gave Ash his Pikachu back, while Ash recalled he had a Pidgeot once. During the Gym match, Falkner sent his Pidgeot, after his Dodrio got defeated. Pidgeot easily dodged Ash's Pikachu's Thunderbolt and blew him away with Whirlwind. Ash setn his last Pokémon, Charizard, who flew into the sky with Pidgeot. Using Agility, Pidgeot was able to gain the advantage to dodge Charizard's Flamethrower. Charizard repeated its attack, but Pidgeot used Whirlwind, which repelled the attack back to Charizard and hit it, which hurt its wing. Using Wing Attack, Pidgeot hurt Charizard, who was unable to dodge. Despite his injured wing, Charizard managed to fly off, so Pidgeot used Agility to speed up and Quick Attack to wound Pidgeot. Charizard flew after Pidgeot, who used Agility once more. This time, Charizard trapped Pidgeot in a Fire Spin and then finished it with Seismic Toss.
