Feminia


 * Feminia is a planet in the Zone portion of the Generation 1 [continuity family]] 

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

It also doesn't exist anymore.

In 2010, Cybertronians visit Feminia for the first time.

Zone
Many years later, the new Decepticon Emperor of Destruction Violen Jygar sends his Nine Great Demon Generals to Feminia in search of the Zodiac energy source. Since it's not there, they blow the planet apart to show how intimidating they are. The Autobot Supreme Commander Victory Saber rapidly coordinates the evacuation of as many people as he can, including a young boy named Kain, but in the process fails to escape himself and is trapped on the surface when the Decepticon Generals crack the planet like an egg. And that was the end of Feminia.
