Palutena from the Kid Icarus series has been leaked 2 days ago for Super Smash Bros for Wii U & 3DS and right now is confirmed as a playable character. She may not though even if the screenshots are real. She could be an assist trophy but we haven't seen assist trophies before on the 3DS so we don't know for sure. But, her poses have never been seen out of these screenshots so she is in Smash Bros 4 or the creator of the fake went all out and even animated her. She would have some serious move-sets too and for more info, go on to YouTube, and go to GameXplain and they will have a discussion about her and the leak.
