The Tyrant on the plane from Res Code Veronica was an absolute bitch to beat, hardest boss I have ever faced in a game.
Metal Gear REX from MGS was always a cool fight, especially with the section with the Ninja begging for you to kill him ( also the fight with the Ninja earlier on is great ).
The Evil Pigs from Tombi/Tomba were novel, as you beat them by throwing them into giant bags, which would trap their evil spirits.
Death and Dracula fight from Castlevania Portrait of Ruin. By this point you will have faced them both a lot in previous games, but never together.
