Dragon Overlord Babylon. Ship-Zetta hasn't met him, but is aware of the power and strength he once held. In the game, when Babylon comes to help out, Zetta actually describes his presence as 'an honor' in all seriousness.

Of course, there are more on the ship, but Zetta is so completely out of touch with himself he's only barely aware of a possibility of respecting some of the very few Overlord-class people he's met.
