This is actually an alternate reality Naruto from the Road to Ninja movie called Menma. He apparently merged with Tobi (haven't actually seen it, just going off what I've read about the movie) which made him look like this. He's not a SasuNaru love child.
Lol I know that! XD Ive been dying to see that movie too! X) I know his name was Menma and how its like, opposite universe.I didn't know about the part with him merging with Tobi though. I was just saying Memna looked so much like Sasuke and Naruto combined. XD
