David Marcus

David Marcus was born in 2261 to James T. Kirk and Carol Marcus. He was raised by his mother because she wanted him to become part of her world, not his father's.

In 2284, David began working with his mother on Project Genesis, a device which could transform the molecular structure of a planet instantly. Becoming impatient for results, David used protomatter, which was highly unstable, to obtain the desired results. This decision would ultimately lead to the failure of Project Genesis.

A year later, David and his mother were ordered by Commander Pavel Chekov, under the influence of Khan Noonien Singh, to deliver Project Genesis to Admiral Kirk immediately.
