So... something very particular that I am dealing with right now in my current writing is that the main villain which I am writing is supposed to be someone overwhelmingly intelligent.
It's not that this character isn't flawed, as a matter of fact in his backstories and previous endeavors he was someone who was very easily irritated and often would fail because society seemed to be against him and what he was trying to do, but he learned from those failures and continued working towards his goals until everything fell into place - at which point the story begins.
Which means that from the starting point of the story, the villain is already supposed to be developed, and extremely intelligent, essentially flawless.
He has a plan in order to become immensely powerful both in terms of combat and in terms of having influence over others. So powerful in fact, that his plans are essentially perfect.
But it's quite difficult to write a villain who is flawless, as you have to find a really good reason for them to lose in the end.
In my previous series, my main villain was overwhelmingly powerful and had a great amount of influence over people, excessively manipulative, etc. However he was very overconfident in himself because of this. When your villain is overconfident, it's easy for them to overlook some major thing that will lead to their downfall.
But what about a villain who is meticulous to the point of insanity?
Someone who freaks over every last little detail, ensuring that everything is going perfectly according to plan.
It's going to be an adventure writing this villain - most particularly forming plots that are successful, with one particular point ending in their loss.
On the other hand, it could be this very meticulous nature which could lead to the loss of the villain.
The very fact that they are able to predict things with certainty, as if they knew exactly how things would play out - would mean that a wrench in their plans would mean all the more chaos.
I'll have a lot of fun with this. But first... I have to figure out a plan in the first place.
