Day 18 - Favorite Princess
I like that she’s a sweet person, and yet to her (and maybe in general on Ooo) there is nothing wrong with torturous, non-consensual experimentation on other people. If AT were a very different series, maybe she would be Fran Madaraki.
(Though I don’t think he’s as much of a scientist, Gumball’s treatment of the Candy Kinders hints at a similar callousness.)
