One trope that will never not made me not go feral is when it's a interspecies relationship and a (usually tiny) human goes defensive mode over their non-human partner.
Like, that scene in Beauty and the Beast right before the Mob song when Gaston calls the Beast a monster and Belle gets so mad and just goes "he is not a monster, YOU ARE!" with the most offended face expressions ever
Or a similar scene in Monster in Paris where Lucille goes "there sure is a monster in Paris but it's not him it's you" while using her whole body to shield Francour
Or that scene in Shape of Water where they are trying to break Amphibian Man out and that russian doctor walks in and Eliza just instinctively shield AM, no hesitation
And just how offended Charlie got when someone disrespected Bumblebee. "He is not a weapon" and "HE IS MORE HUMAN THAN YOU EVER BE!!!" while kicking and fighting a guy twice her size. Girl was standing on business
Just an imagine of a tiny human girl protecting her non-human, tall AF boyfriend. Love it
