Random duo but Vania and Morro would be THE best duo. Specifically Morro after the DotD because i loved how he acted in it and Vania after she became queen. Imagine their interactions
Vania, eating ice cream: you had you rule over a bunch of people when you didn’t want to too???
Morro, who was recently summoned by Vania who had a breakdown because of her responsibilities and then had another after realising she summon a once-evil-potentially-still-is ghost: Girl, i had to rule over a bunch of DEAD people with the actual ruler breathing- no, STARING down my back. Trust me, i get it.
Vania: You kinda look like my dad
Morro: *appalled* please don’t ever say that again. I saw your family photos. He was so ugly???
Vania: *mumbles with a pout of trauma* on the inside too…
Morro: I literally almost took over all the realms.
Vania: Which means you’d be great at helping me find out how to rule part of one!
Morro: That’s your crown???
Vania: *looks up wide eyed* Yes?? Why? Is it ugly?!
Morro: *staring at her in confusion*…usually I’d say yes, but weirdly enough you make it look good.
Vania would be an accidental menace who has no idea what she’s doing and keeps getting in trouble, and Morro has to stick around or else he’ll have to deal with her in the departed realm at this rate. Even when Vania gets more comfortable with being queen, she keeps summoning Morro because despite Morro being heavily against it, they’re friends.
