Gyareon (name subject to change >_>) has been added to the original post. I could have done a bit more to it, however as you only asked for the head on the body, that is all I did, as well as a few minor colour changes. It now just looks like a very angry Vaporeon, or the perfect Shoop-da-whoop set-up... You decide :D.
Wow, Slowflake, that's a great find! Where did you find it? [and are there anymore?]
On another note, Shadian Vise's Spirio (again... name subject to change) has been added to the original post, I did two versions of it just because of the potential I saw in it. The first looks quite good in my opinion, however the second is a bit odd, and I am thinking of maybe lowering the head a little bit so it looks slightly better.
Still working on Gameboy's Vaporeon + Gengar. This has me stumped at the moment, however I will do it!
Also, really Fant? That's cool I guess :D It was just a quick mock up I did as I had the sprites open and thought I would try something with it.
