Some pretty cool information here on Boss Fights and a link to the PDF that the thread links to. Recommended reading for DMs and the like. Players should probably avoid it unless you’re the type that likes to go out and buy a copy of the module your DM is running or wait till he’s in the kitchen getting nachos and you skim through his notes. Funny story there, I used to interweave encounter and room descriptions of multiple dungeons that I created just because one of the players would do that and then he’d be completely confused as to what was coming up. Good times.
Oh and the guy to the left would make a good boss fight don’t you think? Definitely has some BBEG potential IMO.
