a secret weapon. A sequel was released for the Nintendo Entertainment System titled Iron Tank (Great Tank in Japan), which establishes the setting as World War II Normandy. Ralf's next appearance was in action shooting game Ikari Warriors, released a year after TNK III. Instead of driving a tank, Ralf now fought his way into the enemy's lair on his own, along with his new partner Clark Still (the Player 2 character in the game) in order to protect the Ikari village. Ikari Warriors was followed by two sequels: Victory Road (also known as Ikari Warriors II) and Ikari III: The Rescue), with the third involving Ralf and Clark into rescuing a presidential candidate's child from terrorists. In the international versions of the Ikari series for the NES and in Iron Tank, Ralf was renamed Paul. Ralf and Clark would resurface as members of the Ikari Team in The King of Fighters fighting games series, along with their mentor and commanding officer Heidern. The team would be featured as a group of mercenaries who enter the annual King of Fighters tournaments to investigate a possible controversy made by several criminals, such as Rugal Bernstein and the NESTS cartel. Although the Ikari Team has undergone slight roster changes as the series progressed such as the retirement of Heidern, who returned in only with them in The King of Fighters 2001, replaced by his adoptive daughter Leona in The King of Fighters '96 (appearing in all the following games except The King of Fighters XI) as well as the introduction Whip in The King of Fighters '99, Ralf and Clark are two of the few characters who have remained constant, appearing in every game in the series. He also appears in The King of Fighters XII, which does not feature official teams (however his teammates from the 1996 tournament are all present and in the sequel, Ralf does team with Leona and Clark to form KOF XIII's Ikari team). Ralf has also appeared in the 3D game KOF: Maximum Impact and its sequel. Maximum Impact 2 also features , an enhanced version from his character with a stronger defense. However, this character was removed from the update version, KOF: Maximum Impact Regulation "A". Other games from the series featuring Ralf are The King of Fighters Neowave and The King of Fighters: Kyo; he appears in both of them with the Ikari Team
