The character of Worf (Michael Dorn) had a complicated life on Star Trek, especially when it came to his family tree. He was raised on Earth by human foster parents, and eventually had a child who wanted nothing to do with him. To top it off, after he was a fully grown man well into his career with Starfleet, he learned he had a brother. Worf was like an onion: with every episode that focused on him, a new layer was revealed. Throughout his tenure, he went from a Klingon born into a disgraced family to a Klingon diplomat with the trust and friendship of the Empire's Chancellor.
