Sharko is a shark and the main character (sometime as anti-heroes an "protagonists") of the series. 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.
