Star Trek: All 5 Actors Who Played Worf's Son, Alexander

[هَـ-ђāŵĩ-ـَاوِي]

Everyone's favorite Klingon, Worf (Michael Dorn), had a son in Star Trek: The Next Generation and the character has been played by five different actors throughout the Star Trek franchise (so far). Worf's son, Alexander Rozhenko, was a surprise to the Klingon Security Officer. After a brief relationship in TNG season 2, episode 20, "The Emissary," half-human half-Klingon K'Ehleyr (Suzie Plakson) became pregnant with Worf's child. She would keep this from him until two seasons later in the TNG episode aptly named "Reunion," when the pair cross paths again. Tragically, K'Ehleyr was killed in "Reunion", leaving Worf responsible for Alexander, the son he had just met.
