Nate's Unfezant

Nate's Unfezant (Japanese: Kyouhei's Kenhallow) is the first Pokemon that Nate had caught in the Unova region and is his second Pokemon overall.

History
Unfezant first appeared as a Pidove in Enter Rosa and Snivy! where he was hit by Tepig's Ember attack, which angered the Tiny Pidgeon Pokemon. In the battle, he was defeated and captured by Nate who needed him for the Unova League.

In Enter the Genius Gym Battle!, he had fought against Aspertia Gym Leader Cheren's Patrat. During the battle, he showed his speedy agility and strong attacks, but was unable to defeat Patrat due to his attacks being unable to hit it. He was easily defeated by a powerful Super Fang.

He had a battle with Hugh's Pansage in BF010 during Nate's second battle with him. During the battle, he was easily outmatched by its Acrobatics and finally defeated by a nerve-wrecking Seed Bomb.

In BF014, he was used against Roxie's Koffing and Whirlipede. After learning Air Cutter, she was able to take down his opponent using it combined with spinning around, which weakened her Koffing and defeated it with Quick Attack. Later on, he used the same methods despite having weak skills to defeat the Curlipede Pokemon while using her newest move: Aerial Ace. But when she battled against her Garbodor, she was quickly poisoned by Toxic and fainted from exhaustion.

In BF016, he was battling with Rosa's Snivy to master its speed for the next Gym battle. After taking damage from Leaf Tornmado, he evolved into Tranquill and used a stronger version of Aerial Ace. Their battle was postponed when Wave attacked the group with his Jellicent.

In BF019, he had his third Gym battle against the Castelia City Gym Leader Burgh. Against his Shelmet, he was able to counter its Acid attack, but was weakened by Energy Ball and Struggle. Despite this, he was able to use a combination of Air Cutter and Aerial Ace to defeat his opponent before falling to his Leavanny.

In BF029, he was lent to Rosa after Nate decided that he needed three Pokemon for the Battle Subway. Tranquill returned to Nate when Rosa returned to them in Mistralton City.

Sometime near Mistralton City, he greets Skyla's Swanna, and flapped his wings in excitement after the Proud Pokemon looked down at him. He was later used to battle the Swan Pokemon where he was outmatched and unable to defeat her. despite getting burned by Scald and then having his Facade attack fail. Suddenly, he evolved into Unfezant thanks to Nate's confidence and belief in him, and allowed him to learn Sky Attack, which had blocked Swanna's Scald, and took it down as well, knocking out the Water/Flying-type Pokemon.
