Donkey Kong first made his appearance in the 1981 arcade machine called Donkey Kong, in which he faced Mario, now Nintendo's flagship character. This game was also the first appearance of Mario, pre-dating the well-known Super Mario Bros. by four years. Donkey Kong is the carefree, lazy, dumb, yet trustworthy hero of Donkey Kong Island. He is also part of the Mario Kart, Mario Golf and Mario Tennis series. Should be an easy P&G!
