Ash's Boldore

Ash's Boldore (Satoshi's Gantle) was the eighth Pokémon Ash caught in the Unova region.

History
Ash caught his Boldore as a Roggenrola in BW037 after he helped it to save a group of some other Roggenrola from Team Rocket. After an intense battle with Tepig, Ash caught it. It was used again in BW038 in order to search for the missing Audino in a town.

In BW050, it used Flash Cannon alongside Tepig's Ember (Flamethrower) and Axew's Dragon Rage to escape from Dr. Zager's helicopter at the Battle Subway.

In BW062 it saved Tornadus, Thundurus and Landorus by using Flash Cannon on the helicopter piloted by Dr. Zager over and over again until joined by Pikachu, Axew, Emolga and Pansage to destroy the cages the trio was in.

In BW063 Ash used it to battle Clay's Excadrill. During the battle it evolved and at the same time learned Rock Smash and Rock Blast and helped Ash win the Quake Badge.
