This Data Fully Functional Star Trek The Next Generation T-Shirt features an image of Lieutenant Commander Data looking as alluring as an android can muster. Data is the first and only Soong-type android to enter Starfleet. Data's belief that he had the potential to be more human made him one of the most popular characters on Star Trek: The Next Generation. His quote in response to Lieutenant Tasha Yar's question about his capacity for love was, "I am fully functional."
