Vortian

"Zim loves Vortians. He knew that the Irkens were used to be allies with the Vortians before things get out of hand when Larb did it. Guess that's his fault of course."

--Su Ji-Hoon, Dirty Little Secret

Vortians are a highly intelligent race of scientists and engineers who inhabit Vort.

Biology and Appearance
Vortians have digitigrade legs with elongated tarsals. As a result, Vortians walk on their "toes" as opposed to their entire feet. However, their feet lack toes and seem to be pointed at the end. They have "horns", which are likely more like shelled tentacles as they are mildly ambulatory as opposed to stiff. They have tiny eyes of a single color, and their heads are large, and shaped vaguely like that of an Irken.
