The difficulty and length vary wildly for boss fights in video games. It’s not always the final boss fight that’s the most challenging, especially in RPGs; however, some of these battles, upon launch, took too long. Some encounters are infuriating, whether it’s due to an overwhelming amount of health or that they can one-shot entire parties without issue.

While they are easier now, we cannot forget how tiresome some of these battles were upon a game’s original release. Some of these fights could be easily won through shenanigans, but even those can take an inordinate amount of time.

Which boss fights were the longest and most grueling in video games?

5) Admantoise (Final Fantasy XV)

Final Fantasy XV’s Adamantoise, at launch, took around five hours or so to complete, though there were easier ways to manage this. Packing 5M hp, this colossal tortoise can take even the strongest party a long time to overcome. Beating it gives an accessory that gives a character 9,999 HP.

It’s a long, frustrating battle; even when using the Ring of Lucii, it could still take 45 minutes to complete. For video games, especially modern ones, this super boss is one of the most frustrating.

4) The End (Metal Gear Solid 3)

The End may be the best boss in the entire Metal Gear Solid franchise, if not one of the best boss fights in all PS2 video games….
