>>103820834>Aren't Irkens just flesh husks strapped to a robot?
Yes and no. A PAK is like an Irken secondary brain, installed and activated on birth. As such, it's just as much a part of that organism's "natural" physiology as a liver or kidney. They can't live without them, but the PAK still needs a body; The only recorded instances we know of them attaching to non-Irkens are through mix-ups or sabotage.
But more to the point: Irkens may have machine minds, but their lives are lived in flesh.>They don't grow, they don't change.
Not true at all. In the first episode, Tallest Red comments on Invader Larb's increased height, which is how he got assigned to Vort instead of Blorch. In addition, one unfinished episode would have revealed that the current Tallests are only slightly older than Zim, and were part of the same generation of Irkens.>Unless the plot of one episode involves him trying to keep blending in to Earth society by artificially making himself taller....could work.
This is a common plot device used in most realms of fanon, yes. Usually it boils down to one or more of the following:>Earth food>PAK programming>environmental mutation>self-experimentation
So yeah, pick your poison.
