Clair's Kingdra was a powerful Pokemon that Clair used in Gym battles.
Kingdra was used in two battles against Ash. During the first battle Ash used Pikachu, but had to switch to Noctowl when Kingdra's Dragon type characteristics allowed it to resist Pikachu's electric attacks and gain the advantage. Although Noctowl used Confusion, Kingdra simply aimed Hydro Pump at the wall to prevent it from colliding with it and easily defeated the Flying type. Right after the match they had to forfeit because Team Rocket stole the Dragon Fang.
