He has the whiskers, which Naruto only had because he was born with them thanks to Kushina being a Jinchuriki at Naruto's conception and birth. It is MORE likely that she was the Yang halves Jinchuriki, or that Kurama was split for some reason and put the Yin half into Menma and the Yang half back into Kushina.. or the Yang half never left her. The Whiskers are a genetic marker of a Kurama jinchuriki's child. Henceforth it is 100% likely that Hashirama and Mito's kids had whiskers too.
