Mario

Mario is the eponymous main character and protagonist of the long-running and highly successful Mario (series). He was created by Japanese video game designer Shigeru Miyamoto and also serves as the main mascot of Nintendo. Mario made his first appearance as the protagonist of the arcade game Donkey Kong, released in 1981. Since Super Mario Bros., his trademark abilities have been his jumping and stomping 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 and Fire Flower. Games have always portrayed Mario as a silent character without a distinct personality.

Physical Appearance
Mario's distinctive look is due to technology restrictions in the mid-'80s. With a limited number of pixels and colors, the programmers could not animate Mario's movement without making his arms "disappear" if his shirt was a solid color, so Mario got overalls. They did not have the space to give him a mouth. As a result, Mario has a mustache. They could not animate hair. Due to this, they used a cap to bypass these problems. Mario's creator Shigeru Miyamoto has also stated when interviewed that Mario wears a cap because he finds it difficult to draw hair, the same reason Mario and Luigi have mustaches.
