20 years earlier before the events of Tekken 5, during the 2nd Iron Fist Tournament, The CEO at the time, Kazuya Mishima, ordered his scientists to create a new type of military weapon. This entity was known as Roger. A few years after the "death" of Kazuya. Roger ran away and met a female kangaroo. They then had a child, whom they decided to name, "Roger Jr."

20 years later, Roger was kidnapped and taken away. Roger Jr. and his mother joined The King of Iron Fist Tournament 5 to find Roger and, after a long struggle, they found him. But Roger was living the easy life, unconcerned about his family. Roger Jr.'s mother was flabbergasted at the sight of her husband and ultimately decided to divorce him.
