Lian enjoys seeing people fight, a trait that her mother claims runs in the family. She also appears to be quite intelligent for an infant. An example of this was when she pointed to Speedy, and said (in plural form) "Dadas," recognizing both the original and clone Roy Harper as her father.
Lian appears to be only a couple of months old. She has auburn hair, gray eyes, and a few teeth. Being only a quarter Vietnamese, she has a more Caucasian appearance, like her father and maternal grandfather, but with epicanthic folds like her mother.
At age 2, Lian resembles her father more, having more angular features from her paternal side. Though the shape of her eyes is still like her mother's.
Cheshire brought Lian along on their search for Speedy, though Roy thought that she was better off in her aunt Artemis's care while they fought. Safely tucked in in her mother's baby sling, she enjoyed seeing her parents fight their way through a Tibetan monastery. When Roy and Jade finally found Speedy, Lian giggled as she saw someone who looked exactly like her father.
When Crusher Crock and Jade Nguyen went to pay their last respects to Artemis at Gotham Cemetery, Jade carried Lian with her. Lian slept through the entire conversation where her mother and grandfather swore to confront the Mantas.
