15 Longest Boss Fights That Will Take Hours On Your First Playthrough

Penance – Final Fantasy 10

Fancy a boss with 12 million HP? That’s Penance, Final Fantasy 10’s most powerful super boss who’s released once all the Dark Aeons have fallen. Not only can it absorb elemental damage and insta-kill your party with an attack called Judgment Day but it also has a second form. Again, if you know what you’re doing (or happen to get lucky with Yojimbo casting Zanmato), then it’s not terrible. But that just elevates this fight from unbearably long to bearably tedious.
