The last boss of any video game. One of the most if not the most climactic fight in the game.

Usually the most difficult as well, but in some games this is not necessarily the case.
Technically, Sephiroth is the final boss of FF7, but because it's a staged fight many consider Safer Sephiroth to be the final boss.

Ganon at the end of LoZ: OoT was weak.
A Stalfos is harder than him.

Halo didn't need a final boss. An all-out Covenant assault would have done the trick. But nooo, Bungie had to throw in that albino... thing.

Sometimes, people jokingly refer to the internet as a game of sorts, and, like all games, it must have a final boss. Who or what the final boss truly is has been disputed, but one of the more accepted claims is that the position is held by Scott Willoughby, aka StaringVacantly.

You know what's fun? Fighting 4 bosses in a row without checkpoints, with 1 boss' attacks being completely unavoidable and 2 more being heavily RNG dependant to not screw you over, then fighting an extremely frustrating and unfair boss ON THE SAME HEALTH BAR
