The Icon of Sin in Doom 2. That thing spat endless streams of nasty enemies at you, health and ammo weren't as common as one could hope for, and there was always the chance that it would spit on right on top of you. That was instant death, even with an invulnerability cheat.
That and the final boss of Descent 2 was a challenge. Its 'weak point' was a little nub on its back, and it does the smart thing and turns to face you all the time, while it pounds Earthshaker missiles into you. That's right, the most powerful missiles in the game, which you only can ever get a handful of.
