I tried and tried to think of a bad guy I hated, and I couldn't think of any bad guy at all besides Kuja and Sephiroth, and I happen to like them both. Then "Ansem Seeker of Darkness" popped into my head so I was going to make a wall of him, but instead I found this image of "Master Xehanort" Which I find him very annoying as well.
I hope you'll enjoy~ The image isn't the best quality I know, but it's partly the color changes and layers on it that make it looks blurry, sorry for that.
