Well, I just wrote about finding out whether your hero was a hack and slash man or a dash man, and I hope that got you thinking about your characters, but you realize that the same applies to your villain? It does.
Hack and slash villains are the very nasty evil ones who no one likes and who enjoy brute force. I'll still talk about the previously mentioned centuries (17th 18th and 19th) so we won't get confused here. As with a hero, your villain can use a saber or some other hacking weapon. Cutlass if he's a pirate, privateer, or vicious navy man from the Napoleonic period.
And yes, villains can have dash too. These are the showman kinds of villains who are maybe a bit of a dandy or more highbred. Again, this can apply to pirates or highwayman (if your villain is a highwayman) because they are the kind of people who have dash. Sometimes, your villain might have more dash than a hero. In fact, (in the reasoning that opposites attract) It would work, in my suggestion, to pair a dashing hero with a hack and slash villain and a hack and slash hero with a dashing villain. It's well known that hack and slash men have little respect for dashing chaps. Even though dash does not make a man less of a man, a hack and slash person might not appreciate his devil-may-care attitude.
There's also a third thing I'm going to mention here that I didn't with the heroes, though if wished, it could apply to either, and I will be talking about this in a later post about hero and villain "grey areas" and what to steer clear of when you're doing that. Your villain may not be either hack and slash or dash, he might just be a cold vile person. In that case, he's a knife person, a torturer. This is how I portrayed my villain Jack Moore in my book Freedom Come All Ye. These villains are cold-blooded and ruthless, but they sometimes do not like to get their hands dirty. They will have lackeys to run around doing all the hard stuff while they wait and brood for the hero to fall into their clutches; then they'll take a turn and torture the hero a bit. These villains can usually be cowards where only their hate and anger drive them to do what they do. They're the types where, in the last fight, they might try to run or plead and when your too-good hero spares them, they try to stab him in the back. These are the nastiest lads, but they make the best of villains.
I'll be talking more about villains later, so please check back. If you want to read more, go and visit Lynnann Richards' blog Character Chat as she has done a couple posts on writing villains as well.
