10 Hardest Bosses In Final Fantasy History
4. Ruby Weapon - Final Fantasy VII
The PlayStation Final Fantasy trilogy was infamous for its superbosses, and the one that started that trend was the Ruby Weapon. To this day, Ruby Weapon remains one of the most harrowing bosses in Final Fantasy history. Like Omega Weapon before it, this fight has burned Ruby Weapon into the fandom's memory, with the monster showing up in future games to recapture the thrill - such as having an entire storyline dedicated to it and its siblings in Final Fantasy XIV.
Just getting your party to level 99 isn't going to cut it with this dude, the only way you're going to survive is by doing hours of prep work - getting the right materia, unlocking the right skills, making sure every party member has maxed out health etc.. And even with all of that, Ruby will pull one last fast one on you by using Whirlwind to remove your other party members from play if they're not KO'd.
Just getting a shot at beating this boss requires jumping through insane hoops, so the fact that Ruby Weapon is also packing the hardest-hitting attacks in the entire game just feels like insult to injury. By the time you've beaten Ruby Weapon, Sephiroth will probably look like a very edgy gnat to you, because you've seen it all.
