Shen's Conquest or The Rise of Shen was a conflict when shen wanted to get himself back on the throne of Gongmen City.
Battle of Artisan Village
Boss Wolk and his pack were robbing the metal of Musicians' Village to use for Lord Shen's cannons. When he saw Po, he said "A Panda? That's impossible" due to the fact that he and his wolves had supposedly neutralized the threat of the pandas. Mocking Po's fat body and his fluffiness, he was surprised by Po's agility. After the rest of his pack had been defeated, he charged at Po with his hammer and struck a hard blow to his face when the panda was distracted by the symbol on his arm. Boss Wolf escaped, laughing.
Invasion of Gongmen City
Shen 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 Masters Storming Ox and Croc, but was pushed back by Master Thundering Rhino, who shattered several of Shen's blades. Shen, however, was prepared for this, and unveiled his new weapon. Thundering Rhino prepared for battle, but 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.
First Battle of Gongmen City
Po and the Five tried to get to the Tower of Sacred Flames, but some wolves spotted them. Po and the Five battled through Gongmen City.
Boss Wolf encountered Po and the Five again in Gongmen City as he attempted to stop them from rescuing the two surviving Kung Fu masters, Storming Ox and Croc. Having noticed how he was outnumbered, he ran away and escaped on a rickshaw cart. He and Po fought across town, using their carts to dodge and escape each other's attacks. But despite Po's success in finally catching him, Boss Wolf ended up leading Po and the Five into an ambush at the front gates of Shen's palace.
Battle of the Tower of Sacred Flames
Later, when Po and the Furious Five were brought before him in handcuffs, Shen discovered that Po didn't know about the massacre of the pandas or Shen's role in it, and he laughed and taunted him about his ignorance. He ordered the Wolf Boss to fire the cannon at them, but Mantis quickly extinguished the fuse and knocked the wolf out, which bought Viper enough time to pick the lock on Tigress' cuffs. Once they were free, Tigress and Mantis destroyed Shen's cannon and Po lunged at Shen. However, when he saw the marks on Shen's tail feathers, he was struck with a memory of his past, and realized Shen was there the night he lost his biological parents. Shen only confirmed this to him with satisfaction, and then used this distraction to escape to the Fireworks Factory, where he had several more cannons waiting. He ordered his warriors to open fire and bring the tower down with Po and the Five inside. Despite this, they manage to escape as the building fell. Frustrated, Shen ordered his troops to start loading his ships to begin his conquest of China.
Battle of Tower of Sacred Flames
Some time later, Po infiltrated the factory to confront Shen, ruining the Five's plan to destroy the building. As the two fought, Shen easily outmaneuvering Po, he taunted Po again by telling him he saw his parents abandon him and that they never loved him. This again distracted Po, enough for Shen to reach his most powerful cannon, which he used to blast Po out the factory and into the river.
Second Battle of Gongmen City
Po made it on the boat and attacks Shen's wolf army, thus freeing the Furious Five. During the battle, Master Storming Ox and Master Croc join in, along with Shifu. Then when Po was being fired at, Tigress pushes him away and she gets hit. All of the Kung Fu warriors set themselves on pieces of the boat, tired. Po then swam to a sunken boat, where Shen fires him once more. Po, who was concentrating in inner peace, evades the attack and throws it into the river. Shen orders to fire him again, but Po kept on evading till he throws the attack at Shen, destroying the boat. Po finds Shen, and tells him that he has to leave his past behind. Shen didn't care and attacks Po, but ends up killed. All of the villagers cheer for Po, ending Lord Shen's plan to take over China.
