What is the mutagen for?

I know there as been lots of speculation as to what the mutagen was for. We know it's dangerous and unpredictable outside of Dimention X, but we have yet to learn the real intent of the mutagen aside from terraforming the Earth so that the Kraang can live here.

Has anybody thought the purpose of the mutagen could be used to create more Kraang?

I know that sounds weird, but bear with me. All the kraang we've seen talk with a masculine voice. The only exception is Kraang prime, and even Kraang prime was confirmed to be quote unquote male.

So that could mean two things... One the Kraang have no actual gender and some how reproduce by budding.

Or two they are created through some other means.

We are given some hints of something to this in Metalhead. After Donnie makes that "You're mother wears army boots" taunt. And instead of immediately attacking, the Kraang controlling Metalhead says that comment showed ignorance of their species. Before he says "The ones known by you as mother..." before Donnie cuts him off.

So what does that statement mean "The ones known by you as mother..." Answer "Do not exist"?
