Hook Jaw first appeared in Action #1, inspired by the success of the film, Jaws. It was one of the strips that provoked the public campaign against Action, causing the comic to be briefly withdrawn from the shelves. In 2011 Hook Jaw made a return in the British anthology comic, Strip Magazine, with the old Action strips coloured and re-lettered.
Despite his seemingly horrific actions Hook Jaw is never the villian. He is simply a force of nature. The villian is the greed of mankind who seek to exploit the oceans resources for his own ends without thought of the consequences. Hook Jaw passes no judgement on the morality of mankinds actions. To him we're nothing more than meat to be ripped apart and eaten.
