Which video game character was originally called 'Jumpman'?

Mario is a fictional character in the Mario video game franchise, owned by Nintendo and created by Japanese video game designer Shigeru Miyamoto. Acting as the company's mascot, as well as being the eponymous protagonist of the series, Mario has appeared in over 200 video games since his creation. Depicted as a short, pudgy, Italian plumber who resides in the Mushroom Kingdom, his adventures generally center upon rescuing Princess Peach from the Koopa villain Bowser. Mario's fraternal twin brother and sidekick is Luigi.

Mario debuted as "Jumpman" in the arcade game 'Donkey Kong' on July 9, 1981. He is shown to be a carpenter and has a pet ape named Donkey Kong. The carpenter mistreats the ape, who then escapes to kidnap Jumpman's girlfriend, originally known as 'the Lady' (later named Pauline). The player must take the role of Jumpman and rescue the girl. Jumpman was renamed "Mario" in 1982's 'Donkey Kong Junior', the only game in which Mario has been portrayed as an antagonist since.

With more than 600 million units sold worldwide, the overall 'Mario' franchise is the best-selling video game franchise of all time. The franchise has branched into several media, including television shows, film, comics, and licensed merchandise.
