Biography
Excadrill was first revealed to Ash and Cilan in BW009: The Bloom Is on Axew!, when Iris sent him out so he could assist in rescuing Axew from a wild Scolipede. However, he refused to help and stayed in his inactive state. Iris then rescued Axew herself. Excadrill came out of his inactive state in order to fight the Scolipede, after it accidently kicked him. His powerful attacks such as Drill Liner and Dig sent Scolipede flying into the sky. Excadrill then gave a victory cry before returning to inactive state.

Excadrill made a brief appearance in BW020, where Iris sent him out in order to help find Ash and Pikachu, who had fallen down a hole created by the Sunglasses Sandile. He refused to help and so stayed in its inactive state, thereby forcing Iris to recall him.

Excadrill was sent out again in BW027 in order to fend off a flock of irate Swoobat. However, once again he stayed in his inactive state. He was the recalled after being hit by an Emolga's Attract.

In BW036 It had a battle with Langley's Beartic. At first, as usual, it was in it's inactive state but Beartic provoked it and suddenly it was battle ready. When it heard Langley order Beartic to use Rock Smash it brought back bad memories for it. and after the battle it went back to drill mode. Iris revealed that she captured Excadrill as a Drilbur after saving it from falling into a chasm. The had beaten every trainer that crossed their way and during a tournament it evolved. When Excadrill was pitted against Drayden's Haxorus it was easily defeated by Rock Smash. After the battle, it went into its inactive state and wouldn't listen to her. Cilan came to the conclusion that it disobeyed Iris because it was ashamed that it lost to Drayden's Haxorus and couldn't face her. During the night, after hearing a heartfelt apology from Iris, Excadrill opened up and forgave her.
