Ah yes one of my favorites, Evil Overlord tip #7. Last wish, last request, last thought I think not. How many time have we seen this play itself out. Our diabolical overlord has the hero right in his sights and feels the need to prove he is, in fact, smarter. Obviously, he is, the hero is doomed, but only if we follow this tip.
Think about it, Bond Villains are notorious for this one. Megalomania is fairly standard in the Evil Overlord business but get some medication or something before it ruins you. We use the T-800 in this photo because it is more identifiable then Sky-net itself. No mercy, no negotiation just kill it to achieve your ends. Its the Overlord way!
