In the original Armored Fleet Dairugger XIV, Captain Newley was Admiral Dick Asimov. He was the highest ranking officer aboard ship with Captain Ise Shinji (Commander Hawkins) as his executive officer. The dialogue for the English language Voltron adaptation gave the appearance that Hawkins outranked Newley. However, the animation in several cases gave clear indication of their former ranks. In some cases, Asimov's lines were visibly given to Hawkins
