Nurith NupurJohn De Lancie as Q
This actor made his debut in the very first episode of the Next Generations series. But he might not have even dreamt at that time that he would soon become a fan favorite. On screen, he could be seen punishing the crew of Enterprise and putting them through various tests, but in the end, he saved them from the mess he placed them in the first place. Since his time here he has worked on several movies and tv series and even wrote a book.
