[Villain's POV] Hi, I'm the local bandit leader/crime boss/unscrupulous rich guy and a no-name guy's just walked into MY territory and started making waves. How do I get rid of him?

Preferably without too much cost and inconvenience on my part. I've seen the movies, I know how the game's played. If I move against him overtly, I'm gonna get my ass kicked in every way possible.

So what should I do?

Explosives. Gratuitous amounts of explosives. Heroes have this really irritating tendency to dodge bullets or only take grazing blows, have hidden flasks of antidote for whatever poisons you might be planning, and tend to gather a small ragtag horde of diverse followers.

Blow them up. Kill as many of their followers as possible, as swiftly as possible. This is the important thing though: once you have them incapacitated, drop more explosives on them, and then put each of them in a cage. Once in there, before they wake up, drill a goodly sized hole in each of they skulls, and set off a powerful enough explosive to destroy the skull. And for the love of god, do not gloat over them at all until they're headless corpses. Just to be safe, grind up those corpses and dump them in the nearest body of water.

On top of that, do not let your guard down for the next few years. If you find yourself, or anyone else, saying "No one could have survived that", *then they probably survived that*. If you see any sign of them again, be sure to send your underlings to investigate and deal with it.

Worst case scenario, you end up crippling them and have to do this again, but it keeps them out of your hair for a while. Best case scenario, given your method of overkill, you build up a reputation know better than to fuck with.
