In the fictional world of Enterprise, Crewman Daniels is semi-regular character.

He is footsoldier in the Temporal Cold War and is from the 31st century. He was first seen in Cold Front as a member of Archer's crew. After the events of the first season finale, he is no longer present on the Enterprise, but his time travel devices are still there. The quarters seem to have been banned from other crew members except in cases of emergency involving the cold war. Crewman Daniel's came back on the scene in the episode "Carpenter Street, in which he sent Archer and T'Pol back to the year 2004 to investigate why some Xindi Reptilians were on Earth in that time period.
