There'll Be a Royal Wedding

The opening scene here is classic. Zarkon is drinking a glass of wine but decides to hurl the goblet at Lotor, which cracks him squarely in the forehead. The reason for violence? Zarkon is disgusted at his son's efforts to take over Arus. When Lotor whines about Voltron always mucking up his plans, Zarkon advises him to find a weakness in Voltron's armor. Enter Haggar with her latest Robeast which is designed to fight best underwater - where Voltron is weakest. When Lotor wonders how they'll trick Voltron into fighting in water, Haggar produces a tank of 'mini-robeasts' that resemble tadpoles.
