Most revolvers have 5 or 6 chambers, but some have as many as 7 or 8. It depends upon the maker of the gun, the caliber, etc.
I don't know what a "supervillain" is, but it sounds like something from a movie or video game.
Cryptic, you need to forget about everything you've ever seen about guns in movies and games, because they are wrong 99% of the time. May I recommend you sign up for a basic firearms class at a local range, gun club, or gun shop?
