Tak

Tak is a female Irken and is also one of the main antagonists of Invader Zim. While she was taking a test to become promoted from an Irken Elite to an Irken Invader, the power was destroyed due to Zim trying to get a snack from a snack machine. She then got stuck inside a room causing her to miss the test. She pleaded with the control brain to see if she could retake the test again, but she had to wait for another 75 Earth years and was sent to planet Dirt as a janitorial drone. She then escaped by scavenging all the broken equipment, etc and made her own custom ship and SIR unit who she named "MiMi" and then headed out looking for Zim to redeem herself to the Tallest by stealing his job as an invader by conquering Earth. Though, she failed due to the resistance of Zim, GIR, Dib, and Gaz, she was then forced wondering around space as her hatred for Zim grew even more.
