— Klaus to Derek in The Hybrid
Derek was a human used by Klaus to complete the transitions of Paige's pack. He was also the boyfriend of Paige and was ultimately killed by Klaus after the experiment failed.
Derek was a human who lived within the pack of werewolves, due to his relationship with Paige. He was compelled by Klaus to feed all the hybrids which Klaus made. At one point in the episode, Klaus fed Derek his own blood to heal him and then killed him, but since he had Klaus' blood in his system, he most likely turned into a vampire.
- Derek is of English and Old German origin, and the meaning is "people's ruler".
- Derek died with Klaus' blood in his system. His current status is unknown, but most likely due to Klaus' blood, he might be a vampire. It is unknown whether he completed the transition or not.
- Physically, Derek has similarities with members of the Mikaelson Family.
- Derek was one of the only known humans to know the existence of supernatural entities.
