Feminia

Surprisingly not a giant doily.

Feminia (フェミニア) is a prosperous planet populated by a humanoid race. Among its native life forms is a species of intelligent pink flying creatures which vaguely resemble Earth rabbits. One of the world's primary points of interest is the Prime Energy Tower, a huge structure with energy bursting from the top of it.

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. Enter the New Supreme Commander, Dai Atlas!
