What is the name of Data's daughter in TNG?
Answer
Lal
Data’s daughter in Star Trek: The Next Generation is Lal, the android he creates in the episode “The Offspring.” Lal is built from Data’s own positronic-neural design and becomes the closest thing he has to a child.
Data creates Lal after studying human family relationships and deciding that he wants to experience parenthood. He initially presents Lal as an experimental offspring, but the android quickly develops individuality, emotional awareness, and a strong bond with Data. Lal chooses a female appearance, though she can alter her form and identity.
The story ends tragically when Lal’s developing positronic pathways begin to fail. Data attempts to transfer his own neural patterns to save her, but the procedure does not work. Lal’s final experiences, especially fear and love, become central to the episode’s exploration of whether an android can possess human emotion.
B-4 and Lore are Data’s android brothers, not his daughter. Soji is another synthetic being connected to Data in later Star Trek continuity, but Lal remains his daughter in TNG.
