A lot of the stuff I'd say is already mentioned, like Jinpachi and Tabuu.
Ah, I know. Castlevania 3 way back on the NES, first form of Dracula and also the hardest. Two imprisoning firewalls, then a third huge one coming up beneath you. Simple? Ha.
Apparently moving around while the first two walls are about to appear causes them to be further apart. Except when it doesn't and they trap you and you're completely screwed without Alucard. Even once you get the two walls apart, the timing for the third wall erupting beneath you varies from 2 to 5 seconds. What's that? You've actually dodged THAT firewall as well and hit him a few times? Good! Now watch as Dracula teleports directly on top of you while you're trapped by the fire!
Say what you will about ol' Draccy getting beaten and revived so often, he knows how to combine his attacks for maximum effect. My other candidate comes from his insane latest incarnation in Order of Ecclesia. First phase not so bad, but the second has multiple one-hit-kills. Of particular frusturation is a point where he combines attacks wherein he spawns SIX roaming and jumping hellhounds then immediatley follows up with the powerful 'Destruction Rain' while you're still dealing with the hounds. And in case this doesn't quite finish you, he'll rip your throat out with 'Soul Steal' and regain energy to boot.
