Azmeltosh: Literally anything and everything can and will happen before she finishes this fetch quest.
I imagine this would resolve after a fight when Zim realizes she hates dib too because the very first thing Dib did when seeing Katia is threatening to dissect her like he did with Zim even before he showed he was malicious. Then Zim will reassure Katia that she's a great minion.
If you want more crack crossovers like this this one just wait because I just finished a show and I've got another one cooking. If you hate crack crossovers then you're shit out of luck.

Auserr: I like this art style! Katia's fur looks very fuzzy. Funny thing, I've actually been working on a crossover idea too.

Azmeltosh: @Auserr: thank you i dont do digital at all really. i actually just did it in pencil then imported it to csp to trace it then color it. its nice to hear youre doing a crossover i warn you mine will be way dumber. dont mess with me kid

Auserr: @Azmeltosh: Haha. Don't worry, I'll stay in my lane.

Whenever I've tried to trace a pencil drawing to make it digital it always ends up looking bad. So nice job on that as well!
