Christie was unable to win The King of Iron Fist Tournament 5. She was struggling to discover a way to save her grandfather when Eddy Gordo, who had been loyally by her side, suddenly vanished without a trace. She searched everywhere for Eddy, but she was unable to find him. Ultimately, Christie was left with no choice but to return to Brazil alone.
Christie continued her search for Eddy when she returned to Brazil. Surprisingly, her grandfather also disappeared from the hospital, allegedly sent to the Mishima Zaibatsu for treatment. Christie figured that Eddy?s disappearance was somehow connected with the Mishima Zaibatsu, as well, but she couldn?t put it all together. When The King of Iron Fist Tournament 6 was announced, Christie headed for Japan to get in contact with the Mishima Zaibatsu and to gather clues about the disappearance of Eddy and her grandfather.
