Tristan's Excadrill

Tristan's Excadrill(JP:Kento's Doryuzzu) is the fourth Pokemon on Tristan's team.

History
Excadrill was introduced as a rowdy Pokemon in Drillin' Time, where he attacked trainers and took advantage by using its Sand Rush ability to win in battle. When he battled Tristan, he managed to take down two of his Pokemon(Oshawott and Tepig) who had a type advantage against him, but he was defeated by Tranquill's Aerial Ace and multiple Air Cutters.

He was revealed to have been caught in An Odd Friendship, where he teamed up with his fellow teammates(Oshawott, Tepig, and Tranquill) to battle N's Pokemon. When coliding Excadrill's Drill Run, Tepig's Flame Charge,Tranquill's Aerial Ace, and Oshawott's Razor Shell together, they managed to defeat N by teamwork.

In Knowing, he was used to battle Hilda's Braviary. But since the valiant Pokemon was unable to batle due to disobedience, he was used to battle Bianca's Tepig and won the battle. He then learns that his new rival was being disrespectful to Flying-types and has a battle with him which ends in a tie, and begins their anxiety against one another.
