As an Oshawott, Burgundy's Dewott is defeated by Cilan's Pansage in a past Gym battle. She later used Dewott to battle Cilan once more, this time against his Dwebble. Despite the type advantage and Dewott's good offensive attacks, it could not break through Dwebble's strong defense. It quickly became fatigued, and Dwebble defeated it with a Shell Smash and X-Scissor combo.
Burgundy chose Dewott to participate in the Clubsplosion tournament in The Clubsplosion Begins! where it began its battle with Iris's Excadrill. In Search for the Clubultimate!, Dewott fought against Iris's Excadrill. It started off by using Ice Beam and froze Excadrill partially, but he was able to get rid of the ice easily. When he dug underground using Dig, Dewott fired a Water Pulse attack into the hole causing a geyser effect that shot Excadrill out of the ground. When he attacked with Drill Run, Dewott used its two scalchops to block his attack. However, the attack knocked its scalchops out of its hands.
Just before Excadrill attacked it with Metal Claw, Burgundy told Dewott to guard itself and take the attacks. It was so that it could initiate Revenge which dealt a lot of damage to Excadrill. That also gave it a chance to retrieve its lost scalchops and use Razor Shell again, but it was still blocked by Excadrill's Drill Run. As he used Focus Blast, Dewott attempted to counter it with Ice Beam but to no avail and it was hit dead on. However, it was not finished just yet. After taking a combination of Dig and Drill Run from its opponent, it was defeated and Burgundy was knocked out of the tournament.
