Want me to do a direct mod of Zyzz?
Looking at the images, it would be a simple job, and if you tell me who you want him to replace, it'll be simple enough to do.
Ie, if you want him over Cloud, I can do that, and even include some custom weapons I made before if you give me a theme. Such as katanas only, longswords only, greatswords only, etc.
Or if you want him to be someone else, such as Sephiroth, that is very easy to do as well.
If there's a precise outfit that Zyzz wore that you want, I can do that for you.
an example could be a typical MMA outfit, which has tight shorts, arm and leg wrapping and either no shirt or a black tank top
