His parents loved him, people began to find joy in fireworks and when Shen began to become obsessed with them and in the art of making weapons with them. Scared of what could happen with their son, his parents asked the Soothsayer what his future would be if he continued down the path he was on. The soothsayer then told them that she had a vision that his supposed destiny would be destroyed by a warrior of black and white. Hearing this and fearing any problems in his plans, Shen lead his wolf followers to attack and decimate a nearby farming village, populated by giant pandas. When his crime was discovered, Shen was exiled by his father from his home and his throne turned over to Master Thundering Rhino and the Kung Fu Council.
Deep in the mountains, Shen's wolves worked tirelessly to complete their master's ultimate weapon. When the Wolf Boss informs him that they had run out of metal to use as material he orders him to attack the farthest villages and steal all the metal they could find. While he and a group of wolves attended to that, Shen decided it was time to move forward with his plans.
He traveled to Gongmen City and marched up to his former home. Once there he confronted the Kung Fu Council, telling them he was there to take back what was his. In the skirmish that followed Shen easily out fought Master Storming Ox and Master Croc but was pushed back by Master Thundering Rhino, who shattered several of Shen's blades. Shen was prepared for this and unveiled his new weapon, a cannon. Thundering Rhino prepared for battle but was was no match for Shen's device and was killed. With Thundering Rhino dead Shen threatened to turn his cannon on the city unless Storming Ox and Croc surrendered. He had the two masters imprisoned in Gongmen Jail and planted Master Rhino's Cloud Hammer in his courtyard as a trophy.
With the Council out of the way Shen ransacked the Peacock Palace, even throwing his father's throne out the window and replacing it with his cannon. He then questioned the Soothsayer about his future but she informed him that nothing had changed, that he would be defeated by a warrior of black and white. He declared this to be impossible but is quickly proven wrong when the Wolf Boss returned and informed him that he had fought against a panda. Shen, greatly angered by this, ordered him to bring the panda to him so he could prove the Soothsayer wrong.
Later when Po and the Furious Five are brought before him in handcuffs, Shen taunted Po not only about his appearance but his ignorance about his past and Shen's role in it. He ordered the Wolf Boss to fire the cannon at them but Mantis quickly extinguished the fuse and knocks the wolf out. This bought Viper enough time to pick the lock on Tigress' cuffs. Once they were free, Tigress and Mantis destroyed Shen's cannon and Po tried to attack Shen. However, when he saw the marks on Shen's feathers he realized Shen was there the night he lost his biological parents. Shen used the distraction this caused to escape to the fireworks factory, where he had several more cannons waiting. He ordered his men to open fire and bring the tower down with Po and the Five inside. Despite this, they manage to escape. Frustrated, Shen ordered his troops to start loading his ships to begin his conquest of china.
Some time later Po infiltrated the factory to confront Shen, ruining the Five's plan to destroy the building. As the two fight, Shen easily outmaneuvering Po, he taunted Po again telling him he saw his parents abandon him and that they never loved him. This distracted Po enough for Shen to reach his most powerful cannon and blast Po out the factory into the river.
Confident Po was dead, Shen has the recaptured Furious Five chained up and suspended above his ships as they sailed out of the city. Much to his shock, Po returned and tried to rescue his friends and defeat Shen once and for all. Shen ordered his gunners to blast him but Po nimbly moved along the rooftops, preventing them from getting a clear shot, and then jumped onto the ships to engage Shen's army, now that they couldn't fire without hitting their own men. Shen could do nothing but watch as Po freed the Furious Five and joined forces with Masters Storming Ox, Croc and Shifu. Finally losing his patience, Shen ordered the Wolf Boss to fire the main cannon but he refused to kill his own men. In response to this Shen strikes him down with one of his throwing knives and fires the cannon himself, knocking all the kung fu warriors away and blasting through the boats they had set up to block his fleet.
As his ships entered the harbor Shen watched as Po swam out to one of the destroyed boats and began making Tai Chi motions. Unphased Shen ordered his gunners to open fire and finish the panda. Amazingly, Po used a technique Shifu had showed him earlier to catch and deflect the cannonballs, sending them back and destroying all of Shen's ships and cannons. When Po confronts him on his main ship Shen asks him how he did it, how he could find peace after what he did to him. Po tells him that it was time to let go of his past and choose his own future. Instead, Shen attacks Po with lance and knives. Shen's swordplay overwhelms Po but as they fight he accidentally cut through the ropes holding the remains of his cannon. He realized this too late and as the heavy weapon falls Shen closed his eyes, accepting his fate.
