Well, I wanted Orochi to have a Susanoo, because one time when he was on a mission, he throughly defeated and he only had a little chakra left. His partner was in trouble, but he could do nothing to save him. But intead of letting his partner die, he jumped in front of the jutsu the enemy had used to attack. But instead of dying because of his sacrifice, the Susanoo awakened inside him and protected him, because he truly wanted to protect someone.

And as the Amaterasu, he could've awakened it from intense training. But at first he didn't have enough chakra to actually perform it. But during a raid of some minor village, he was caught up in battle with the village leader and needed help. So his master transfered enough chakra to him to perform Amaterasu, and the black flames engulfed the leader and the village. He passed out from its usage, but he then trained to up his chakra levels, so he could use it more often, or at least without passing out.
