He is Marina's boyfriend and protects her from being eaten by Zig. Sharko is very strong and would do anything for Marina, giving a big thrashing to whoever tries to harm her or himself .He'll do whatever Marina asks to make her happy, even if it means doing something he doesn't like or finds unsafe. He seems to like table-tennis very much.
Sharko is very protective of Marina and will do anything to keep other people from taking her. He is also very serious when it comes to fighting Zig and his friend Bernie. He is a very willing person, often doing whatever Marina is doing to keep her happy, even though he occasionally reailizes that Marina's desires can result in some dangerous consequences (See Nurse Marina, Mermaid in the sky, and Goofy Astronauts). He also has an obsession with Table Tennis even going as far as to abandon Marina and leave her with his idiot hammer cousin (See the episode HammerHead Cousin). He does acts mainly as a grumpy kind of bodyguard rarely smiling and leaving the Marina's side. Sharko also seams to have some sort of flirtaceous side to him (See Manic Mermaid). He gets embarrased when his parents come even though he is around the age of 40. Even though he finds clever ways to comically defeat Zig. He has shown to have a small brain about 1/2 the size of Bernie. Despite his antagonism with Zig, it's revealed he becomes lonely and sad without Zig around to beat up (See "Goin' Home).
Sharko looks like a large Great White Shark with a long snought and a fin that can act like a blade. He is dark blue in colour and has a grey belly. He also has sharp teeth which he uses with great proficiency.
