Failure to include a large, red, clearly labeled Self Destruct button is, of course, a violation of SVLOSHA regulations.
Sure, you can have all kinds of ideas on how to bring a world that's spurned you to its very knees, making it tremble in terror at the very mention of your name-but odds are, if you're spending your time in snug unitards and engaged in pitched rooftop battles with the masked crimefighting element, you most likely don't have the requisite knowledge of particle physics to make your dreams a reality.
In the past, locating a viable henchman with that kind of technical skill was, at best, a risky proposition. Usually, the super-villain of yesteryear had to resort to kidnapping a Government employee and forcing him to use the Death Ray he created for peaceful purposes for unthinkable evil, and that puts an entire extra step between you and the delicious taste of lasery revenge.

Unlike the other categories, the Secret Weapon henchman is usually one of a kind-rather than being recruited like the others, he's usually "promoted" from within the ranks of the many, many henchmen who will inevitably fail in their assigned tasks, thus incurring your wrath. Either that or someone who mocked your plans for a perfectly viable battalion of giant, mobile chess pieces designed to revolutionize warfare for the 21st century. Either way, it's going to be someone you don't care for.
After all, you don't want someone you actually like to be subject to horrifying experiments that will turn them into an unstoppable creature-once a man, but now something... other-powered only by its hatred for the world. Oh, and while we're on the subject, invest in some heavy chains. That thing's not going to be too pleased with you either.
