The son of Jack and Beverly Crusher, he's a bright young man, who's almost too intelligent for his own good. He first arrived on the Enterprise D with his mother right after Captain Jean-Luc Picard assumed command. Picard realized that he understood many things beyond his age and appointed him an acting Ensign. He matured over the years and eventually entered Starfleet Academy. (The first time he took the Academy entrance exam, however, he didn't pass (Fries & Vejar, 1988). See Coming of Age.) Starfleet wasn't to be his destiny, as he participated in an incident in which a fellow student was killed. During the year he had to repeat before graduating, he became restless and bored with his studies.
While visiting the Enterprise, he met The Traveler who helped him transcend space and time and achieve his true potential. Wesley Crusher was played by Wil Wheaton.
Many viewers found the character intensely irritating. There was at one point a Usenet newsgroup named "alt.wesley.crusher.die.die.die."
