Death Bringer from Golden Axe on the Sega Genesis. He has 2 unkillable skeletons that can take off an entire health bar (At max you can have 5) with their attacks and can randomly stun-lock you to death. His axe attacks take off a whole health bar. But his true BSness comes from his magic. If you get knocked down while he is standing, he hits you with at least 1 undodgeable spell that takes off at least 1 health bar (sometimes 2). Being that he is the final boss, you aren't likely to have very many lives and continues left, so he will kill you 'till you die from it.
Even worse is the fact 1 can only use 1 magic spell and he can use as many as he wants. I have only bested him 1 time in the 15 years I've owned the game. Only way to beat him is with a second person keeping the skeletons occupied while you keep spamming running kicks to keep him off his feet.
Never have I faced a foe that I could not defeat, except this guy.
