On "Star Trek: The Next Generation," Jean-Luc Picard, played by Patrick Stewart, is the captain of the USS Enterprise. Picard favors diplomacy, and prides himself on his education and sophistication. Picard's first mate is William Riker, played by Jonathan Frakes. Riker is far more aggressive than Picard in dealing with potential problems. The show also stars Brent Spiner as Data, an android who frequently has difficulty reconciling human emotions with logical actions.
Other characters on the show include Geordi La Forge, a blind pilot played by LeVar Burton, and Beverly Crusher, a doctor played by Gates McFadden. One of the most controversial characters on "Star Trek: The Next Generation" is Crusher's son, Wesley, an ensign played by Wil Wheaton. Wesley is considered one of the least popular characters in any "Star Trek" series, and was written out of the show after the fourth season. The show also features characters Deanna Troi, a woman with psionic abilities played by Marina Sirtis, and Worf, a Klingon warrior played by Michael Dorn. As of 2015, Worf has appeared in more "Star Trek" episodes than any other character.
