After the conclusion of The King of Iron Fist Tournament 4, Xiaoyu had been feeling down. Panda, worried about Xiaoyu, was searching for a way to cheer Xiaoyu up decided the best approach would be to find Jin Kazama. Panda tried various methods but was unable to find Jin.
One day, Xiaoyu burst into the room excited. "Panda, I've decided to enter The King of Iron Fist Tournament 5 and I need your help once again"
Panda didn't quite understand Xiaoyu's reason for entering the Tournament but decided to help if it would make Xiaoyu happy.
Panda participated in The King of Iron Fist Tournament 5 as Ling Xiaoyu's bodyguard. However, upon discovering that Heihachi Mishima was not dead, she left the Tournament with Xiaoyu.
Just when Panda thought that she could now rest easy, the peace was interrupted by Mishima Zaibatsu's declaration of war. Xiaoyu said that she must once again join The King of Iron Fist Tournament and Panda reluctantly joined her.
