I guess I like it, but... I dunno, I guess it'll have to grow on me. Though I am excited~ It looks like it could be a normal type, but I think that this thing will be able to use attacks from her Eeveelution sisters (in my head it is a girl, okay?), given that one screenshot from the game in the second scan that looks like she's summoning some sort of fire. what if it turned out to be fire/fighting However, I really can't say that I think this thing will be anything other than a new type. The secrecy revolving around its type just makes me wonder, and unlike her brothers and sisters, Ninfia just doesn't have that appearance like Glaceon or Umbreon have that scream what type they are, so I'm going to bet either Normal or something new, though I know the chances of that happening are really low.
Though something about it reminds me of Milotic for some reason. I know that that has nothing to do with it, probably, but once you see it, it doesn't really go away. PLUS, now that we have a confirmed Eeveelution in Gen VI, I think we can safely assume that there will be plenty of returning Pokemon, and that Gen VI might go the way of Gen II and IV and give us several new evolutions. Though, then again, GF could just say that Eevee would be the only Pokemon with a new evolution, we really can't tell anymore :I
Edit: now that I think about it, aren't Eeveelutions introduced along with some new evolutionary mechanic? In RBY we had stones, GSC we had friendships at certain times of day, DPPt we had locations, so I wonder what would trigger it this time. I don't think that we will be seeing the same mechanics used for this, and I think this one is going to be really unique since its the only Eeveelution introduced (or at least thus far, but really if they were going to make more then they would reveal them too, wouldn't they?) this gen.
