Whilst a common one between my gals would be seeing their Pokemon hurt (like, life threatening kind of hurt) by someone or Pokemon curelty in general, for Margaret specifically it's having someone looking down on her. It ties back to her rather rough relationship with her family to which she had to consistently try and prove her worth, from which really stem quite a few of her issues. But yeah, if she feels she's being looked down on or underestimated by someone who thinks themselves higher than her it would absolutely let her emotions fly and drive her to knock them down a peg and then some.

I would say a bit of both, but sorta leaning more so towards "cries". In my mind if the situation is calm/relaxed enough, a pokemon could choose to do a more anime-like cry and say it's name - but it's rare. Likely also something that's more common with tame Pokemon rather than wild ones. Otherwise they prefer to stick to more animalistic cries and sounds.

Laura would be boobs! She has a weakness for a good set of pecks on dudes or some real heavy boob on gals (with perhaps a sprinkle of envy in lue of the fact her own are a tad more modest).

Margaret and Midna though are both firmly on team butts. They can both appreciate a good set of cheeks on guys or gals, though the former of the two is distinctly more weak if they belong to a girl.

Oooh yeah. There've been a few like that for me, but it was most recently Midna. I initially was concepting Midna as a far more smug and sassy kind of character in terms of her personality. But as I worked on her design further and decided to have her try and lean more into the spiritual roots of her family, that personality type stopped to feel fitting since her background had essentially shifted.
