Gan Williams was born together with his siamese brother Tavis Williams. Their parents an unnamed Vienamese woman and Walter Williams.

Walter Williams, a second lieutenant of the US army, met a Vietnamese woman while he was assigned in Vietnam for several months until he was assigned elsewhere. Later it was found that the Vietname woman was pregnant and was ostracized for it. She left Vietnam and later found the fabled land of Hsuan in the North China Sea. There she was accepted and gave birth to siamese twins Gan and Travis Williams. Chan Ti performed a ceremony and applied jade herbs and ancient incense and he was able to separate the children. However, after the process, it was discovered that the children were different. Gan possessed the power of thunder while Travis that of the lightning among others. However, their powers apparently became unstable and Chan Ti said that they need the blood of their father to cure their condition. Thus began their search for their father.

Their search brought them to Saint Louis but apparently, was told that he left already. Their bouts of instability brought them to the attention of the army and the Teen Titans. After calming down, they received information that their father was in Maine to which they immediately went. Searching for their father and their unstable powers sometimes caused them to act irrationally resulting in their second bout with the Teen Titans. The battle ended when Wonder Girl arrived with information that their father disappeared after an accidental laboratory explosion. Thinking their father dead, the Williams lost interest in the battle and surrendered. Cyborg suggested that they go to S.T.A.R. Labs where they might find a cure for their condition.

S.T.A.R. Labs however, was not able to cure the brothers. Losing hope, the brothers tried to leave but the Teen Titans came to stop them from leaving. Raven then offered to use her soul self to find the whereabouts of their father and it was discovered that he was being held captive by H.I.V.E.. It was then discovered that their father is actually an alien who crash-landed in Vietnam and is being experimented by the H.I.V.E. Under the H.I.V.E.s control, their father attacked them and the Titans, and the brothers were forced to kill their father. Using the blood from the corpse of their father, S.T.A.R. Labs was able to stabilize the brothers powers, curing them. Thereafter, the brothers went home to Vietnam.
