Unfezant, as a Pidove, was caught soon after Ash began traveling in Unova in Enter Iris and Axew!. Ash tried to catch another Pidove beforehand, but the rest of the flock attacked him and flew away, leaving this particular Pidove pecking at the ground. She proved herself to be a strong battler, holding her own against Pikachu before being knocked out by his Thunderbolt and caught by Ash.
Pidove has mainly been used by Ash to search for other Pokémon, as seen when she was used to find two wild Darumaka in Saving Darmanitan From the Bell! and a wild Snivy in Snivy Plays Hard to Catch!. She played a major role in Snivy's capture, as she was unaffected by Snivy's Attract because of being of the same gender.
Pidove was used against Trip's Frillish in A Rival Battle for Club Champ!. She was quickly defeated by Frillish's Water Pulse. She was later sent to Professor Juniper's lab in Sewaddle and Burgh in Pinwheel Forest! to make room for Ash's Sewaddle, but was returned to his party in The Lost World of Gothitelle!.
In A Venipede Stampede!, she helped clear out a swarm of Venipede from the Castelia City. She was nearly hit by a Sludge Bomb, but was saved by Trip's Tranquill. She then cleared a few more Venipede and suddenly evolved into a Tranquill.
As of Battling for the Love of Bug-Types!, Tranquill was sent back to Professor Juniper's lab while Swadloon stayed on Ash's team but later in Archeops In The Modern World!, Ash brought her back to help a revived Archen learn how to fly.An Amazing Aerial Battle!, Tranquill appears for Ash's gym battle with Skyla, she defeated Skyla's Swoobat after it beat Ash's Krokorok. She then battled Skyla's Unfezant and was knocked to near fainting but Ash switched her for Pikachu. After Pikachu was defeated by Swanna, Ash used Tranquill again but she nearly lost, however Tranquill evolved into Unfezant and learned Aerial Ace, beating Swanna and winning Ash the Jet Badge.
In Cameron's Secret Weapon!, Ash used Unfezant in his Vertress Conference battle against Cameron and his Riolu. Despite Unfezant having the type advantage, Riolu proved to be a powerful opponent, being able to dodge both Gust and Quick Attack before landing on Unfezant's back and serving a close range hit with Force Palm. Ash told Unfezant to shake Riolu off and then strike back with an Air Cutter. However, the Emanation Pokémon was able to dodge the attack and then use Copycat, hitting Unfezant with her own move, before serving another hit with Vacuum Wave. Unfezant tried to attack with Aerial Ace, but the Flying-type's last effort was avoided and countered by Riolu's Circle Throw, which sent Unfezant flying into the arena wall, knocking her out.
