Four villains - Sunmurai, Bathman, Firearrow, and Blackhole - built a machine to rob the Earth of all its water. However, Bathman accidentally broke the machine while chasing a fly. They rebuilt the machine and used it to take all the water from the seas and rivers. The last remaining drop of water informed frozen superheroes on another planet so they could come save the Earth from the villains. It turned out to be just a dream.
