I not going to lie, when I was browsing deviantart yesterday, I saw some pics of this guy and I thought, "Oh, that's some nice fanart". Come to find out that it was actually real this afternoon! Felt really awkward. I mean, the picture I saw WAS fanart (pretty good fanart I thought), but I didn't think this Mewthree was a real design.
If this isn't a new form, I wonder if they would really call this Mewthree? Probably not since I always thought that was a bit weird name to say, but you never know.
I think it would be more interesting if this IS Mewthree, but it has different forms similar to Deoxys. If you get one version, Mewthree looks more masculine, the other more feminine. I only say that cause that picture of him above just doesn't scream out "I'm a boy". Then again, you never know with Pokemon, and its very possible that they will just make it genderless. Just my little idea. Guess I find the design to just be a bit weird, I'm sure I'll get used to it.
Don't know why I'm so surprised at a Mewthree, I always assumed the just didn't want to touch Mewtwo (or any further incarnations of him) at all since he is such a classic or something. Still, I like this news!
