A Dalek's Perspective: Invader Zim

To the Daleks, many Earth-things are vile, and have no value to them, all doomed to be exterminated.

Invader Zim is not one of these things.

We intend on keeping this.

While Zim's incompetence does not make him an example for the Daleks, he shows the Daleks what not to do, when attempting to cleanse a planet of its degenerate races.

To understand this value, we must examine the premise.

The Irkens, a race hardly unlike the Dominators and the Sontarans, select their strongest warriors for missions to further the glory of the Irken Empire.

However, the most eager, Zim, is the most incompetent.

Here is where what not to do becomes apparent to any Dalek.  Any specimen as incompetent as Zim would have been soundly exterminated by the Daleks; contrary to what Steven Moffat believes, Daleks do not have asylums; Cybermen do, because they're weak, but Daleks don't.

We just eradicate defectives.

Furthermore, the Irken seek to expand their territory and victory counts, very much the same as the Dominators, demonstrating that they lack any understanding of the True Way of Life: All that exists will seek to eliminate anything that can potentially compete.  The only way to conquer a galaxy is through total extermination.  No survivors.  They will just kill you.

Thus, any Dalek can quickly deduce just how easily things will go wrong from here.

All the more humorously, they are assigned "SIR" robots, not unlike the Quarks of the Dominators, and of course, Zim gets the most defective one...who, as a malfunction, calls himself "GIR".  GIR frequently demonstrates the kind of behavior that should, by right, lead to an immediate deactivation.  Such as this:

The Daleks need to have their own Doom Song...

Together, the two defects work on their way to conquering the Earth, on to get stopped by the same, single human boy every single time.

A better Dalek would have cleansed the planet completely solo.

Invader Zim is filled with loads of adventures you humans would probably find most amusing, from robots impersonating parents to a giant mutated hamster.  The entire series can be easily found on Amazon, and word up the Dalek pathweb is that there's a movie coming out!
