King Triton is the foil to the aforementioned Crown Of Thorns character.  He is simultaneously his nemesis and his love interest. 

He is based on the giant triton snail, which is the only animal known to prey upon the crown of thorns starfish.

He's a bit of a sad-sack but he's generally thought of as a respected leader within the ruling court.

As he lives with schizoaffective disorder he is very quiet and aloof.  Despite being generally a kind and good hearted person his odd quirks put people off from spending too much time with him, and he only has a handful of people he typically associates with.

He uses a harpoon gun as his main weapon.
