For some reason I just couldn't beat "The Fury" in MGS3 on my first run through. Took me several hours spread across several days. (Including enormous rage - Guess he lived up to his name at least.)
Funnily enough I was able to beat him on the very first try when I replayed the game one year later.
I also had a very hard time with the "Gladiator" from Shadows of the Empire on N64. Back then he was tough as balls and scared the hell out of me lol.
Just look at this at 5:18 ...
Those are certainly not the toughest bosses ever in retrospect, I just remember having had problems with them.
