Look at this guys full color of the last enemy.

According to Madara Uchiha in FB; The main vilain is confirmed to be related to Rikudou Sennin."Naruto's last battle is against a relative of Rikudou Sennin.""I will put an end to this world.""No, it won't end!"

There is something came in my mine that after Madara activated the moon, Kaguya was came out and same goes to this guy too. So that is why he appeared in chapter 867 as a shadow only.
