The Alien Villainess has lime green skin. She wears a black dress, a purple cape, and appears to have makeup on. She resembles the Alien Commander from Alien Conquest but has a transparent pink "brain" rather than a green one.
She has the same emblem on her torso as the Alien Cyborg and the Alien Commander, while she is stated to be the Intergalactic Girl (8827 Minifigures Series 6)'s enemy in her own bio. Since the Intergalactic Girl uses the classic Space logo and her bio mentions Blacktron, it could be concluded that the Space and Alien Conquest themes are part of the same canon. This would show an example of the Collectable Minifigures theme associating different Lego themes.
Her medium lilac cape is actually made out of two parts, unlike the Vampire's cape, which is one part.
“Go forth, my minions, and bring me the universe!”
With a name far too regal (not to mention too long and too unpronounceable) to mention here, the Alien Villainess rules over a vast interstellar empire devoted to one thing and one thing only – total universal conquest! From her towering citadel on the Imperial Throneworld, she sends out fleets of flying saucers to every corner of the galaxy, ordering the commander of each to invade and conquer any planet they find.
From the top of her pulsating purple brain to the tips of her tentacles, the Alien Villainess craves nothing less than absolute control over all of outer space. That’s why it’s so annoying when people try to stop her, especially that pesky Intergalactic Girl who keeps arriving at the last minute, escaping her brilliantly inescapable traps and messing up her plans. Don’t they realize that the universe would be so much better if only everybody would swear eternal allegiance to her?
