Lt. Commander Data (Brent Spiner) has always been my favorite Star Trek character, but I wish Star Trek: The Next Generation had never given the android an emotion chip. Since his introduction in TNG’s premiere, Data wanted nothing more than to be human, so he spent TNG’s seven seasons observing the humans around him. Created by cyberneticist Dr. Noonien Soong (Brent Spiner), Data was a one-of-a-kind technological marvel, with superior strength and an advanced positronic brain. Without Data, the USS Enterprise-D would’ve been destroyed on multiple occasions, and Captain Jean-Luc Picard (Patrick Stewart) considered the android one of his closest friends.
