Interesting...
Clearly, as we've said before, the Palutena in the pictures is its own unique model. It wasn't directly ripped from another source. As it is, I have essentially no doubt that she is in at this point. It has yet to be shown false, whereas most are killed on the spot. Good job making these comparisons.
That said, I hate speaking in absolutes. So while I am convinced it's real (and I think these comparisons do a good job of putting this all away) there is always the possibility that some neck-beard spent the time to carefully construct the image using various programs and sources as he ate hot pockets in his mothers basement, sweating because of the rolls of fat underneath his Cheeto stained Captain America T-Shirt...
Don't know where that came from lol.
Anyway, even with the idea of it being fake...at this point, I don't see how anybody could doubt it.
