I was just thinking over it and was wondering is it possible that Oro has created a new technique where he can resurrect a person and then use the resurrected person's body parts as his own, like an Uchicha's sharingan. Since, we already have a proof that Madara and Danzo could use Hashirama's cells.
If Oro can do it, it will be EPIC!!
