"The Icarus Factor" is the fourteenth episode of the second season of the American science fiction television series Star Trek: The Next Generation.
In this episode, the Enterprise's first officer William Riker must decide whether to accept command of his own starship, and negative feelings surface when his estranged father arrives to brief him on the mission.
Kyle makes several attempts to reconcile but is rebuffed by Will; the tension between the two finally boils over, and they agree to a match of Anbo-jyutsu, a form of martial arts in which the two had sparred while Will was growing up.
The trio eventually learn that Worf is approaching the tenth anniversary of his Age of Ascension; Klingons are expected to celebrate the day with a ritual administered by their own kind.
Wesley, Geordi, and Data program the holodeck as a site for the ritual, in which Worf must traverse a gauntlet of Klingon warriors and endure jolts from the pain sticks they carry.
"[1] Entertainment Tonight co-host John Tesh, in an uncredited appearance, plays a holographic Klingon in the ritual scene, having volunteered for any part on the show months previously.
This episode was noted for the tensions between Commander Riker and his father, which culminates in a round of Anbo-jyutsu, a fictional martial arts form from the Star Trek future.
