Well, i'll start from comics. The Punisher started as a comic character, making an appearence in one of the popular comics, long time ago (Spider Man or Batman comics i think). His name was Frank Castle, he got his family killed by criminals, and he decided, it's time to take out the guns as The Punisher. This is how he got his own comic. Later after that, The Punisher movie saw the day, and was follow by the game, simply called The Punisher (published by THQ).
