Captain Troy Tempest
Troy is the charming captain of the WASP submarine 'Stingray'. Together with his hydrophones operator, known as 'Phones', he patrols the seas, often managing to find trouble amongst the natives.
He seems to be involved in a love triangle of sorts with Marina and Atlanta.

Commander Sam Shore
Commander Shore is the senior officer at Marineville. He has a quick temper and little time for Titan's games with the WASPs. He is Atlanta's father, and is very protective of her.
Shore was crippled in an accident some years ago, and is now confined to a hover-chair that has been designed especially for use at Marineville.
