The Captain was an explorer and treasure seeker and the grandfather of Marvin Meno. Captain Meno was the inspiration for his grandson to follow in his footsteps and take on the same activities. Captain Meno was the pilot and owner of a submarine.
He never returned from his last voyage and it is assumed that his submarine sank along with all his treasure. The only image of the Captain is a faded portrait of him hanging on the wall of The Grand Salon of his submarine.
