Hmm. If I was the final boss first off it would imply that they'd have to beat me in order to win, so my downfall is already written, just waiting either for a really good gamer, or a cheater.
What I would do is simply make the player think they killed me by creating a clone, not stronger but weaker than me so the thing doesn't betrays me easily. Once the player kills him he will think he won and simply leave with some phat loot. Meantime I can either sit and wait for him to leave and get out of it all alive, or set a trap and kill him while he thinks its all safe and done. I would probably let him live and I would start another... whatever I had since if he came to me it means he destroyed everything below me, making me the probable sole survivor.
You see, brute force is not always the answer. Sometimes deception is the key to win.
