Arthur Curry, KING of Atlantis. I highlight King as that is what he is.. a King. Arthur is a brawler, he has been trained well but has been known to fight dirty. Using a mix of his Earth combat skills with Atlantean training he's a force to reckon with.

Aquaman's entitlement can sometimes get the better of him, but at his core he is a generous, sweet person only used to ruling rather than playing as a team. 

I'm looking specifically for someone who can portray his royalty in his voice. He's changed under the surface world to adapt to Atlantean speech and has a more Shakespearean tone to his speech.
