Randall's Unfezant

Randall's Unfezant''' is the first Pokemon owned by Randall. It was with him since childhood as a Pidove.'''

In the Past
Unfezant was first seen as a Pidove during a flashback of Randall's childhood. Pidove was found after being protected by its trainer from two wild Timburr. Since it saw Randall's bravery, Pidove defeats them and becomes Randall's partner. Pidove was trained by Randall and evolved into Tranquill after mastering Aerial Ace. Randall then entered Tranquill in a tournament where they had won 49 Pokemon battles on their own until they battled Alder, the Unova League Champion. The battle's outcome was unknown. Tranquill first appeared in The Start of a Trainer's Voyage! where he was briefly seen with Phanpy while their trainer leave for his Starter Pokemon. He reappeared in A Battle Course of Rivals! where he witnessed Tepig battling against Keith's Oshawott and losing. It then teamed up with Tepig and Phanpy to defeat Team Plasma's Pokemon utilizing its Aerial Ace attack.

In Trading Rages, he battled in an attempt to stop Randall's newly-obtained-and-evolved Escavalier. Since he took attacks from the Bug/Steel-type Pokemon, he manages to defeat it with Aerial Ace and Air Cutter using his ability Super Luck.

In BW14 Randall sent him out by to battle the Gym Leader Lenora in his second Gym battle. Against her Watchog, he manages to take damage from its Thunderbolt attacks, but manages to use Super Luck to boost his Aerial Ace and knocks it out. He later battles against her Herdier, but loses after getting knocked out by Take Down.

In BW22, Tranquill was used once again against Burgh's Whirlipede. Using his quick wits and speedy agility, he manages to damage it a little with multiple Air Cutters with help from Super Luck. He manages to use a powerful Aerial Ace to strike down his foe and defeated the Bug/Poison POkemon. He then battled Dwebble and was knocked out by Rock Wrecker.

In BW44, Randall and Tranquill battled against Keith's Unfezant in order to let Skyla accept their request for a Gym battle. In the battle, Tranquill was outmatched by the Proud Pokemon's stronger power. Since he was unable to win, Tranquill evolved into a male Unfezant thanks to his and Randall's determination. He manages to defeat his rival with a Sky Attack, an attack Keith's Unfezant dosen't know, and won the request instead of Keith.
