Dundee is a minor character from Celebi: Voice of the Forest.
Dundee first appeared when he used his Croconaw to battle Ash and his Pikachu. He ordered Croconaw to launch a barrage of Water Guns. However, Pikachu was able to avoid them as the two Pokémon ran to each other. After Pikachu avoided Croconaw's Slash and Bite attacks, he pushed the latter away with Quick Attack and launched a Thunder Shock on it, but accidentally hit Dundee as well. After the battle, Brock's Crobat showed up to take Ash to where his friends are as they didn't want to miss the boat.
