Song is a minor character in Kung Fu Panda: Legends of Awesomeness.
She is one of the members of the Ladies of the Shade, a traveling band of thieves.
She made her first appearance in the episode "Ladies of the Shade", where she was assigned by the thief leader, Su, to get Po to invite her and the others to the Jade Palace where they plan to craftily steal the Dragon Chalice.
Song accomplished this, but she also had developed a close relationship with Po which helped her eventually make the decision to turn against her leader and aid the panda.
Like her comrades, deceit and thievery was Song's game. Described as an adorable lotus flower, she was usually assigned to put her good looks to use with seduction and infiltration among people.
She also possesses a snarky sense of humor, quoting at one point that earning Po's trust would be easy as long as she wouldn't have to carry him.
However, she gradually develops from this, as she spends a day with Po, partaking in several activities and actually having a great time.
While her feminine charms don't really work against Po (who remains mostly naïve and oblivious of them), some of his kindness and antics rub onto Song. She later feels reluctance and regret over fooling him.
Later, when Po, Viper, and Crane infiltrate her village, she takes a stand and joins their cause in bringing the Dragon Chalice out of there and so redeems herself.
Now determined to take up the leadership of the Ladies of the Shade and turn their profession to something more honest, she parts with Po, promising that she'll never forget him.
