>>95731234>>95747207>Zim was not likely going to get any taller, at least not any time soon>Irken invaders at least are confirmed to be mass produced to be spread more accursed the galaxy and take over planets; infatuated with galactic dominance.>Depending on their bred purpose, they are produced with more or less resources. Invaders are likely made with less to allow more to be made, meaning more can invade and take over planets; very disposable, and are likely greatly mistreated as a result. Zim was ~160 earth years when he invades Earth. But he is considered 11 by his species standards, because planet Irk takes 10 earth years to rotate around their star. Meaning his age is really just based on rotation, not necessarily biological age.
Zim graduated his invasion training at least half his lifetime ago (even invaded his own home planet just after). Meaning he must have been at least equivalent to a late teen or early twenties human back in his first invasion.
Thus Zim is arguably at an equivocal stage of a ~30-50yo. Meaning he either stopped growing comely, or grows incredibly slow (similar to how crocs keep growing after maturity, but even slower growth)
