Yohohohohoho guys, I thought this would be fun to try: I'll be listing in-universe battles that you can rate:
S- God-tier perfection
G- Dugong crap
You'll of course be judging the fight on setting significance, excitement, suspense, variety and conclusion but it's up to you if you just want to vote a letter or expand on your selection. First 10 votes per fight, this isn't comparative, it's individual so I'll just post another fight when the limit is reached.
First fight: Luffy vs Don Krieg
