Seth MacFarlane is an American animator, writer, actor and singer, the creator of Family Guy and American Dad. A devoted Star Trek fan, he has often cast its actors in his own work.
He appeared twice in Enterprise as Ensign Rivers, an engineer. In the third-season episode The Forgotten he is one of the crew reprimanded by Trip Tucker, and in the fourth-season episode Affliction he is seen aboard the Columbia after Tucker transfers there.
MacFarlane later created and starred in The Orville, a science fiction series openly modelled on The Next Generation, which employed many Star Trek writers, directors and actors.
