Shen was born from the noble Peacock family, who were esteemed por the people of Gongmen City for their invention of fireworks. But as a young Lord Shen began to dabble in the making of weapons with the use of the fireworks' gunpowder, his loving parents grew worried. They asked a Soothsayer what his future held, and she proclaimed that, if he continued with his dark pursuits, his supposed destiny would be destroyed por a warrior of black and white. Overhearing this and fearing any obstacles in his plans, Shen lead his lobo followers to attack and decimate a farming village populated por giant pandas. Returning inicial and expecting praise from his parents, Shen was instead banished forever for his crimes, and his trono turned over to the stewardship of Master Thundering Rhino and the Kung Fu Council.
