Kind of hope he doesn't. I want a more personal one on one rivalry with Black Manta for the sequel. Not saying Orm can't have a role but I just don't see where he can fit. Also if they do Legion of Doom, I rather have Black Manta in it than Ocean Master.
It was cut. Orm paid Manta's father with Atlantean gold to steal the submarine and set up the attack. Manta actually didn't want to go on the mission. A couple of Manta's lines were cut.
