The hero of the Mushroom Kingdom, Mario has saved their world and the Princess Peach countless times over the years. Due to Bowser's propensity to return over and over to continue the same ploy to capture the princess and wreck the kingdom, Mario took to hiding and drinking his days away in a Warp Pipe room hidden behind a series of traps. After the heroes managed to convince him to sober up and help them save the princess and the kingdom one more time, Mario managed to heroically (and stupidly) leap headfirst into the mouth of the first monster they encountered. Whether he had extra lives is up for debate. He has yet to be seen again.
