10 Reasons Why Data Was A Dangerous Threat To The Enterprise
4. He Created Another Android Without Telling Anyone
Fans of TNG know that Data had a daughter long before the two daughters from Star Trek: Picard. Her name was Lal, and like Data, she was a Soong-type android. Data assembled Lal in secret, not revealing her existence until she was fully conscious.
Captain Picard, and Starfleet Command, were pretty unhappy about this. And they were right to be. We know from Lore that Soong-type androids have a 50/50 chance of being complete psychopaths. Luckily, Lal took after her father, but it was a real risk creating her.
Picard even states that had Data told him of the project he would have ordered it stopped. Perhaps that’s why Data kept the information to himself? We’ll never know.
