D4 Green (a.k.a Dean) was an engineer on the Federation starship Prometheus. (Star Trek: Prometheus)


Dean hatched in Nasat's largest treetop city's nursery and grew through his larval stage to adulthood never once meeting his parents, as is the norm with Nasats. Once he was full grown and had completed his education on Nasat Dean entered Starfleet Academy in 2374 where he majored in Engineering and minored in Security. Upon graduation in 2378 Dean was assigned to the engineering section of the USS Prometheus run by Lieutenant Commander Durgan Morlon.
