Daniels (Crewman)

Daniels (played by Matt Winston) was the alias of an agent in the Temporal Cold War claiming to be from the 31st century, repeatedly encountered by the Enterprise (NX-01) in the early 2150s.

In April 2151 he infiltrated Enterprise, posing as a crewman (third class) who was one of the ship's stewards. In September 2151, Daniels revealed to Captain Archer that he was actually a time traveler from the 31st century trying to ensure that the Suliban Cabal did not interfere in historical events. He needed the crew's help to track down Silik to find out who he was working for. Silik, however, got the jump on Daniels and apparently killed him. (ENT: "Cold Front")

After the destruction of the Paraagan colony in March 2152, Daniels returned, taking Archer back in time to April 9, 2151 to explain that the destruction of the colony was not originally part of history, but rather caused by interference by the Suliban. He told him how to prove this and returned him to 2152. Shortly afterwards, Daniels brought Archer to the 31st century to help him escape the Suliban, a historical change that wiped out Daniels' entire civilization. Daniels was shocked at this unexpected turn of events and expressed even more concern upon learning that a monument commemorating a "Federation" had never been built. Afterwards, Daniels used his still-intact knowledge of temporal technology to return Archer home through the temporal communications chamber on the Suliban helix. (ENT: "Shockwave, Parts I and II")

When the Na'kuhl temporal faction defeated Daniels' faction when the Temporal Cold War escalated, Daniels barely managed to escape to 1944, where he brought Archer (fortunately pulling him off the superweapon just before it exploded) and Enterprise. The turbulence in the timestream caused by all the temporal incursions ravaged Daniels body, and he died in Enterprise's sickbay, though he was able to give Archer enough information to destroy the Na'kuhl temporal conduit, thereby stopping them from ever invading the 31st century, and thus undoing his death. Daniels sent Enterprise back to 2154, but not before Archer told him he was done with being a pawn in the Temporal Cold War. (ENT: "Storm Front, Parts I and II")

At some point in his life, Daniels worked as a professor at Project Timepiece in 2268. While there, he discovered a gigantic version of the Guardian Of Forever. In an alternate timeline, the crew of the USS Farragut (NCC-1647) used this gateway to travel to 2254 to prevent the destruction of the USS Enterprise (NCC-1701) and restore the timeline.
