Feminia

Feminia is a planet from the Zone portion of the Generation 1 continuity family.

Surprisingly not a giant doily.

Feminia is a prosperous planet where the local sapient life forms are human colonists, or Nebulan colonists of Marvel-type race, or... well, the existence of the planet's hexapod vertebrates suggests they're not indigenous, but if you want to try to determine exobiology rationally, you're in the wrong place.

It also doesn't exist anymore.

Zone

Many years later, the new Decepticon Emperor of Destruction Violen Jygar sent his Nine Great Demon Generals to Feminia in search of the Zodiac energy source. Since it wasn't there, they blew the planet apart to show how intimidating they were. The Autobot Supreme Commander Victory Saber rapidly coordinated the evacuation of as many people as he could, including a young boy named Cain, but in the process failed to escape himself and was trapped on the surface when the Decepticon Generals cracked the planet like an egg. And that was the end of Feminia. Zone
