Ralf Jones (ラルフ・ジョーンズ) is a character from the Ikari Warriors, Metal Slug and the King of Fighters video game series. He also stared as the player character in the shooting games T.N.K. III and Iron Tank. Keiko Ijuu states that his visual appearance in Ikari Warriors was based on Sylvester Stallone's role Rambo, which was popular at the time of his conception.
Like Mario and Luigi, Ralf and his fellow agent (and good friend) Clark Still started out as palette swap characters in Ikari Warriors. In KOF '94, Ralf and Clark were very similar in looks and move repertoire, but by 1995, Clark got a newer stance and win pose, while Ralf retained his old ones. In every new installment of the KOF series, Clark seems to be further and further differing from Ralf, while Clark is a powerful grappler, Ralf is more of a power player, making use of some very efficient long-range attacks. Both characters were redesigned in KOF '99. He is also a playable character in Metal Slug 6, where he has the ability to use his punch to knock out vehicles and can survive up to two shots.
In Gamest's 1997 Heroes Collection, Ralf was voted as the staff's twelfth favorite character. In the character popularity poll on Neo Geo Freak's website, he was voted as the eighth favorite character with a total of 1,038 votes.
Ralf Jones has been voiced by Monster Maezuka from his debut, who also voices Kyoshiro Senryo, Choi Bounge and Benimaru Nikaido. He is also voiced by Scott Casey for the English adaption of the KOF: Maximum Impact series.
