Daniels ( Crewman ) The temporal agent known only as Daniels was an operative from the 31st century and a major player in the Temporal Cold War . Daniels had frequent interactions with the crew of in the 2150s and often assisted them in preventing temporal incursion s by various factions in the Cold War . Encounters with " Enterprise " . Daniels first came into contact with the " Enterprise " crew in 2151 , when he infiltrated the ship posing as a crewman . Working undercover as a steward , Daniels had been assigned to " Enterprise " to capture Silik , the leader of the Suliban Cabal , whom they knew would be boarding the ship at some point . Silik did indeed board " Enterprise " several months into their mission , posing as a Borothan pilgrim , at which point Daniels revealed himself and the true nature of his mission to Captain Archer . While Daniels and Archer worked together to capture him , Silik confronted Daniels and shot him with a particle weapon , apparently killing him . ( ) Despite this , Daniels reappeared the next year , taking Archer back in time ten months , in order to have a conversation with him in secret from the other factions in the Cold War . When Archer expressed surprise at Daniels ' survival , believing that Silik had killed him , Daniels only responded , " " He did . . . in a manner of speaking . " " Daniels instructed Archer in the construction of two extremely advanced quantum beacon s , which the " Enterprise " crew used to detect a cloak ed Suliban stealth cruiser , and prove that the Cabal had attempted to frame " Enterprise " for the destruction of the Paraagan II mining colony . Afterwards , when Silik threatened to destroy " Enterprise " unless Archer handed himself over , Daniels transported Archer forward in time to the 31st century , in an attempt to protect him . Daniels ' actions had disastrous consequences , however , in that removing Archer from the timeline changed history in such a way as to destroy Daniels ' civilization . With no way to return Archer to his own time and restore the timeline , Daniels and Archer were forced to improvise , using Archer ' s communicator and hand scanner to construct a makeshift temporal communicator , which Archer used to communicate with his crew in the 22nd century . Archer ' s crew managed to retrieve a piece of technology that Daniels had left in his quarters on " Enterprise " , and trick Silik into interfacing it with the technology that he used to communicate with the Cabal ' s benefactor in the 28th century . This temporarily turned Silik ' s technology into a means by which Archer could return to his own time , defeating Silik and correcting the damage to the timeline . ( ) In 2153 , Daniels returned to " Enterprise " , which was in the midst of searching for the Xindi weapon in the Delphic Expanse , to inform Archer that they had detected three Xindi - Reptilian s on Earth in the year 2004 . As Daniels could not secure authorization from his superiors to travel back in time himself , he offered to send Archer back in time to stop the Xindi , who were attempting to synthesize a bio - weapon in secret , with which to destroy Humanity . He supplied Archer and T ' Pol with temporal tag s to mark anything that did not belong in that time period for retrieval , and a temporal beacon with which to signal Daniels when their mission was complete . After the successful completion of their mission , Daniels returned Archer and T ' Pol , along with the Xindi bodies and all of their equipment , to " Enterprise " , only moments after they had originally been transported back in time . ( ) The next year , Daniels returned to plead with Captain Archer to not undertake a suicide mission to destroy the Xindi weapon , explaining that Archer ' s role in history was too important for him to sacrifice himself . To make his point , Daniels transported Archer to the , a Starfleet vessel in service during the 26th century , so Archer could witness the historic Battle of Procyon V , wherein the forces of the Federation defeated the Sphere - Builder s . Daniels explained that the Sphere - Builders were attempting to manipulate the Xindi into destroying Earth , so that the Federation would never come into existence , and they could invade the galaxy unopposed . Daniels attempted to convince Archer that the only way to defeat the Sphere - Builders was to form an alliance with the Xindi , but Archer refused , unwilling to risk the destruction of Earth . In the hopes that Archer would change his mind , however , Daniels supplied him with a Xindi initiation medal which belonged to one of the crewmembers on the " Enterprise " - J , revealing that , in the 26th century , the Xindi were members of the Federation . The medal later proved to be an important component in saving Earth , as Archer used it to convince the Xindi - Primate Degra that Human s and Xindi were destined to form an alliance . ( ) Later that year , as Captain Archer was preparing to lead a team to board the Xindi weapon and destroy it , Daniels transported him to 2161 to witness the Federation Charter being signed . Attempting to convince Archer to send someone else on the mission , Daniels explained that , without Archer , the Federation would never come into being , and that it was too dangerous to risk his life . Archer refused , however , feeling that it was his responsibility to destroy the weapon . Later , as Archer was trapped on board the exploding weapon , Daniels transported him and " Enterprise " back in time to 1944 , in an alternate timeline created by multiple temporal incursions by various factions in the Cold War . In this timeline , the Nazi s had launched a successful invasion of the America n East Coast , and had formed an alliance with the Na ' kuhl , a Cold War faction from the 29th century . Daniels appeared in " Enterprise " s sickbay , dying from a condition which caused various parts of his body to exist in different temporal states . He explained that the Temporal Cold War had ignited into a full - blown conflict , and that different temporal agents stationed throughout the timeline had been given orders to change history . This resulted in temporal anomalies ripping through the timestream , causing Daniels ' condition . Before dying as a result of his injuries , he informed the crew that the conflict was initiated when the Na ' kuhl launched an attack on the 31st century using a temporal conduit they were constructing with the assistance of the Nazis , and that he had transported Archer and " Enterprise " to this point in time to stop them . Eventually , " Enterprise " was successful in destroying the conduit before the Na ' kuhl had a chance to use it , an action which had the effect of resetting the timeline and reversing Daniels ' death . Afterwards , Daniels returned Archer and " Enterprise " to their proper place in time , but not before Archer informed him that he was done being a pawn in the Temporal Cold War . Bidding Archer farewell , Daniels told him that , as a result of his actions , the Cold War was coming to an end . ( ) Appendices . Background information . In the script of , Daniels was initially described thus ; " " He ' s early 30 ' s , curious but deferential . " " In the final draft script of , a note regarding Daniels stated , " " He appears as he did in ' Cold Front ' . " " The black costume that was worn by Daniels made its debut in " Shockwave " and was referred to , in the script , as " a futuristic uniform " . Daniels appeared in an early version of the episode . When Mike Sussman pitched the story to Brannon Braga , Sussman planned for Daniels to materialize on the bridge of " Enterprise " at the end of the narrative , planning to retrieve a time travel pod . The pod features into the final version of the installment , containing an unidentified deceased body . In response to Archer asking whose corpse was inside the vehicle , Daniels would have revealed that the dead body was his own . He then would have disappeared , leaving Archer with no more answers . Sussman wasn ' t sure why this story point was ultimately excluded from the plot , but reckoned that the decision was made " at a high level " to keep the episode more mysterious . As a result , Daniels was written out of the tale , and at the point when he would have appeared , the pod instead simply disappears , which Sussman believed was just as effective . He recalled that his initial notions about the identity of the dead body was either Daniels or a similar time traveler . In the final draft script of , Daniels was referred to when Captain Archer , having found that " Enterprise " had accidentally traveled back in time , rhetorically asked T ' Pol , with grim humor , " " Where ' s Crewman Daniels when you need him . " " In the final draft script of , Daniels was initially described thus ; " " His mangled face is a horrifying sight . . . as if patches of ancient , decaying flesh have been grafted onto his skin . Clumps of his hair are missing from his scalp . . . his right eye is pale , almost solid white . " " In a potential story pitched by Mike Sussman , Daniels would have come aboard " Enterprise " and brought , played by William Shatner , into the future , making sure history took the correct course by having him pose as Shatner ' s original character during a significant event . Trivia . While Crewman Daniels appeared to be allied with the United Federation of Planets , Daniels has explicitly stated , in " Cold Front " , that he is not a Starfleet officer . Daniels " dies " twice on screen . The first is in " Cold Front " , where he is killed by Silik . The second time is in " Storm Front " , where he dies as his body undergoes severe temporal flux . Along with Shran , Ambassador Soval and Porthos , Daniels is one of only four characters , outside of the main ones , to appear in all four seasons of " Star Trek : Enterprise " . ↑ In " Cold Front " Archer asks Daniels , " " Are you Human ? " " and he replies , " " More or less , " " with no further elaboration , such as specifying inter - species ancestors or an evolution ary change in Humans . Apocrypha . Daniels makes brief appearances in the " " novels " Watching the Clock " and " The Collectors " . In the latter , his real name is given as Timot Danlen . Daniels also appears in " Agents of Yesterday " , the third expansion pack to " Star Trek Online " ; Matt Winston reprises his role for the expansion . He masquerades as " Ensign Hunter " , assigned to the crew of a 23rd century starship commanded by the player character , in order to prevent the Temporal Liberation Front – an alliance of Na ' kuhl , Vorgon s , Krenim , the Sphere - Builder s , and later the Terran Empire all opposed to the Temporal Accord – from altering history in that time period . After the player is " killed " at the Battle of Caleb IV , Daniels recruits the player as a temporal agent , and brings them forward to the year 2409 ( the year the " Star Trek Online " story begins ) to combat the Na ' kuhl in the game ' s " present " . Daniels begins suffering progressive scarring from temporal flux linked to " the Envoy " , the leader of the TLF . He is killed by the Envoy - revealed to be the Krenim scientist Noye - at New Khitomer . After Noye and his forces are defeated at Procyon V , Daniels ' death is reversed , just as it had been at the end of " Storm Front , Part II " , and bids farewell to the player .
