The other Alien Pitt knocked out all four of them with knock out gas and took Dan's Ultra Eye, knowing he couldn't turn into Ultraseven without it. With her sister faking an illness in order to try sabotaging UG's base, the other Alien Pitt used the saucer to turn Tadpole Eleking into his adult form. After the other Alien Pitt jammed some of the base's controls and hijacked a rocket, Dan found the one controlling Eleking and managed to grab his Ultra Eye back after wrestling her into unconsciousness. After Ultraseven destroyed Eleking, and the two sisters reunited in their saucer. The Alien Pitts took off, but the Ultra would not let them get away. After the Alien Pitts' failed attempt to stop Ultraseven with their saucer's ray, they were destroyed by the Emerium Beam.
