Shen was born from the noble Peacock family, who were esteemed by 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 by a warrior of black and white. Overhearing this and fearing any obstacles in his plans, Shen lead his wolf followers to attack and decimate a farming village populated by giant pandas. Returning home and expecting praise from his parents, Shen was instead banished forever for his crimes, and his throne turned over to the stewardship of Master Thundering Rhino and the Kung Fu Council.
