If you want an epic boss fight, get FFXII. There is a hidden boss, or "mark" in the game with 50 million HP. It took me over ten hours to beat it. Yiazmat.

10 hours? WTF?

At lower levels Yiazmat begins to take exponentially more time to kill, since you're doing less damage and healing more often.
