Vort

"Vort? Zim told me that Vortians was once an ally to the Irkens before they get enslaved. Should've known. At least Lard Nar and Zim are both friends as of now."

--Su Ji-Hoon, Leaving Ningbo

Vort was originally the home planet of the Vortian race and the "home of the Universe's Most Comfortable Couch," as described in an Invader Zim episode, The Nightmare Begins. Vort is inhabited by the Vortian race, an intelligent race of aliens who have goat-like characteristics including hocks on their legs, and horns on top of their heads. The planet was originally in alliance with the Irken Empire and was later conquered by Irken Invader Larb. The possible reason for this was that Zim created a blob monster on Vort Research Station 9 that devoured former Almighty Tallest Miyuki, and later former Almighty Tallest Spork. It is unknown what planet Vort looks like from space, as it was never seen during the duration of that series. Vort is now Irk's top millitary research prison. Lard Nar, the co-leader of the Resisty, is Vortian.
