Ziltoid
What if... Ziltoid/Skibidi Toilet crossover?
I'm not sure I can think of enough material to write a fic for it, so I'm throwing it out there. Who would side with whom? Ziltoid is the reluctant defender of humanity, so he'd side with the Union. His enemy is War Princess Blattaria - would she side with Duchess? Or would they be rivals who distract each other long enough for the Union to make a move?
Either way, Poozer/Skibidi interaction would be hilarious.
