17 years ago 3 children managed to escape from dangerous secret experiments, and now the three of them are wanted by the police for stealing nuclear bombs and bombing several regions and countries. Not only that crime, they also like to rob banks and commit other crimes. The three of them are very intelligent and have above average IQs, the police have difficulty catching them because they are small their intelligence and their agility. they always leave the "SPX" symbol every time they commit a crime... they named their group after that SPHINX
