I don't even really break down Brooklyn 99 by favorite characters because it's the interaction of all of them together that's so fantastic. Okay, that said, Rosa is 100% the coolest one.

I love Bruce Banner & Hulk, Thor, Spiderman, Captain America, every single character in Guardians of the Galaxy. I loved Thor: Ragnarok and last time I checked AO3 I could still claim to have written the only Hulk/Korg fic on the entire site.
