Fandom Snowflake Challenge: Favorite Tropes

Challenge #09: Talk about your favorite tropes in media or transformative works. (Feel free to substitute in theme/motif/cliche if "trope" doesn't resonate with you.)

I'm skipping around the challenge a bit since I'm still constructing my answers for the other ones as I'm way behind at the moment, but this one is one that I know I can answer easily since I definitely have a lot of favorite tropes. I answered last years trope challenge with only one specific trope which I still maintain is a top favorite in recent years, but this will be a more extensive list. Mind you, not all my favorites as that would take forever, just a handful.

( Tropes, tropes, glorious tropes.... )
