Scrambled up a list, I honestly feel like most of it was "oh damn, that DID happen this year" & had to be reminded by you guys, so I get the feeling most of this is just echoing what's been said.
Worst character: Zenitsu, whatever that main villain in SAO who likes to eat souls
Best moment: Giorno beats the shit outta Cioccolata, Doppio's frog phone
Worst moment: *insert something from SAO here, there's so damn many I don't know what to pick*, Zenitsu being mad at not being able to be with little girls
Best performance: Senku, Diavolo/King Crimson, Sonny Strait (though honestly, I kinda wanna vote for him next year)
Best character: Koro-Sensei, Inosuke, Bruno
Best villain: Gentle Criminal, Lil' Slugger, Doppio
Best power: Senku's smarts (...wait, did we nominate this last year?), King Crimson, Metallica
Biggest disappointment: Golden Wind's ending/final fight makes no sense, block takes huge hit due to corona, Mob Psycho 100 II's weird legal issues (I almost put "Part 5's name changes" but that wasn't gonna win)
Best surprise: oh hey, Paranoia Agent's back on Adult Swim after licensing limbo; black clover is no longer on the block; the block slowly returning to normal at the end of the year with some bigger shows announced/premiering
Edit: I FORGOT BRICK SNAKE FOR BEST CHARACTER, MOMENT, & POWER.
