What Makes a good villain?

An age old question when it comes writing and character creation.

After all the villain is some what at times what defines the hero and is the opposing force in the story.

They are often overlooked as nothing more than a bad guy to be beaten without question to their motives and goals.

Most I've seen created by people are very simply straight forward wanting to destroy all and take all the power they can.

A good villain is perhaps one of the hardest things to achieve in story writing and especially if your creating it with it tied to an official character of any form of fiction.

For example an Eggman creation...Lazy very lazy or a characters evil brother or alternative universe version in their own home world.

I'll be adding to this and hopefully form a good guide to helping you form the right villain to oppose your hero or perhaps make you take a second look at your already create villain and rethink your motives and ideas.

In the mean time feel free to send a link or some pics in the comments and tell me about your ideas of a good villain and if you wish request a character review.
