Baal from Disgaea: HoD.
The final story boss is level 90.
Baal is level 4000.
Yes FOUR THOUSAND.
And he has the best gear in the game.
Also In Disgaea 2 one of the first bosses is level 1200, your supposed to lose but if you win you get auto game-overed as it fucks up the plot.
You clearly forgot about Prinny Baal, who's level 6000. That's a pretty large level gap between two fights IMO.

Orphan from Final Fantasy XIII.
Orphan is hard? I beat it on my first go without a single death. My brother beat it on his first go, and he sucks at RPGs. I suppose he would be hard if you didn't have either Vanille or Hope in your party (They both have Curaja. 2 Curajas heal the party to about 60% of your max HP after that move), but still, he's a pushover.
As for me, I haven't come across a boss fight that is "Impossible", but over powered definitely.
1) Freya - Star Ocean 3. Almost all her moves are insta-kill regardless of how much HP you have (except on easy mode, and possibly normal). You can survive her attacks, but it takes hours to set up character builds, and even then, you can only take one or two attacks.
2) Nyx Avatar - Persona 3. Oh. My. God. Smack down the worst (albeit most epic) last boss fight in all the boss fights I've ever fought. 14 forms (if you include Fool), with each form getting progressively harder and longer to beat (starting with about 5 minutes a form). Sure the fight starts off easy, but as you get further into the battle, your supplies start running low, and her attacks become more devastating.
And then you hit the last form.... EPIC WTF!? Not only does Nyx take half damage from every attack type except for Almighty (non-elemental), she gets basically every high-end spell in the game. She also learns two special attacks - first one gives all reflect-all for 4 turns, you don't need any more details than that. Second is her super attack, Night Queen. It does 500 damage (about 80 - 120% of your character's HP), and then puts everyone in a random status effect. If one of your healers get charmed, they can heal the boss back to max health. Congratulations, you just wasted the last 30 minutes.
