Tak is an Irken and a minor antagonist in Invader Zim. Her main goal is to take Zim's "mission" because Zim had ruined her training as an Invader. Vicious and determined, she's more focused on trying to gain for herself an honorable title as an Invader than revenge. She claims that Zim just happens to be in the way of getting it. Despite her repeated assertions, she does show an inordinate amount of anger and bitterness toward Zim with good reason. Fifty Earth years prior to Zim's arrival on Earth, Tak was going through training to become an Irken Elite, with the possibility of being chosen as an Invader. However, Zim caused a major blackout throughout half of Devastis, when he chose to retrieve a snack from a faulty vending machine by using a large battle mech (possibly a Maim Bot, as seen in "Hobo 13") and shooting straight at it. The resulting explosion blasted half the planet's power grid and trapped Tak in a training cell on the day of examination. Despite the catastrophic power outage, all tests continued on the other still-working side of the planet, leaving Tak stranded. She pled her case to her assigned Control Brain in hopes for some leniency, but her request was promptly denied. She was then put into a janitorial squad to do hard labor on Planet Dirt for the duration of seventy Earth years before she could retake the examination.
