Thunderstorm Water Eels

BoBoiBoy Water summons eels of water to aim at his evil knockoff, who laughs at him for using an attack that previously didn't work on him, and shoots geysers as counterattacks. Suddenly, BoBoiBoy turns into BoBoiBoy Thunderstorm, who electrifies the eels. They pierce through the geysers and electrocute the robot, killing him for good.
