Doctor David Marcus is a Human scientist from the Star Trek feature films, the son of Dr. Carol Marcus and James T. Kirk. Raised by his mother and immersed in scientific research, he earned his doctorate young and joined her team developing Project Genesis.
David's controversial use of protomatter advanced the Genesis project but rendered it unstable. Serving aboard the USS Grissom alongside Saavik, he was killed by a Klingon while defending her, a loss that deeply affected his father.
