10 Frustrating Video Game Boss Battles You Forgot You Hated

8. Final Fantasy X - Seymour Flux

The tenth Final Fantasy proved to be the last one with the 'proper' turn-based combat the franchise was built on, leading to a strong positive point in the face of some characters and an overall storyline that many fans grew to hate in the many hours it took to finish.

Whether or not you love or hate FFX though, there's one character everyone remembers through gritted teeth - the undying and forever-annoying Seymour.

Cropping up multiple times throughout the game, the first and last time you fight aren't actually too bad, but that one showdown on the side of Mt. Gagazet, where he goes under the name Seymour Flux, heals himself constantly and deals death through cross-cleaving your party without breaking a sweat before sending you back to a much earlier checkpoint? It was agony.
