Mario

Mario (Japanese: マリオ, Mario) is a character first appearing as the protagonist of the arcade game Donkey Kong released in 1981. Since Mario Bros., Mario has made numerous appearances as a main character in his own series of games, the Mario series, and has become the mascot of Nintendo. Since Super Mario Bros., his trademark abilities have been his jumping powers, with which he defeats most of his enemies, and his ability to change size and gain powers with a plethora of items, such as the Super Mushroom. Games have always portrayed Mario as a silent character without a distinct personality. According to Nintendo's philosophy, this allows Mario to fit in many different genres and roles
