Tremble with fear, fools! As there's a new Doom Lord here to terrorize you all! It's Unikitty- er, I mean Master Fussypants!

From the episode "Ragtag" where Unikitty and her friends challenge the Doom Lords to a game of kickball, with their own castle on the line. But after discovering the Doom Lords pretty much suck at Kickball (she even says herself to them "You TOTALLY stink!" while SMILING to boot!), she actually joins their team to help them win!

Unikitty, I know being nice and helping others is, like, your main thing and all, but sometimes you gotta let things be! I feel like in the interest of "fairness" she'd give Darkseid the Anti Life Equation! Or Thanos the Infinity Gauntlet!

Regardless, seeing her as a makeshift Doom Lord was interesting. I'm curious if Master Fussypants might make a resurgence down the line. I mean we all thought the Doom Lords, themselves were going to be one-offs and THEY came back, so who knows.
