Braxton Captain Braxton was a Starfleet officer from the 29th century . In that capacity , he piloted the Federation timeship " Aeon " and commanded the . Encounters with " Voyager " . Temporal explosion . Braxton was first encountered by the in 2373 , when the " Aeon " arrived in the Delta Quadrant through a temporal rift . Braxton claimed that " Voyager " had been responsible for the destruction of the Sol system in the 29th century , and had traveled back to prevent that occurrence by destroying " Voyager " . The " Voyager " crew was able to counter Braxton ' s attack , however , destabilizing his temporal rift , into which both ships were pulled . Both ships were subsequently sent back to Earth , the " Aeon " to 1967 , and " Voyager " to 1996 . Braxton managed to execute an emergency beam - out before crash landing in the High Sierras , but was unable to retrieve his ship before it was discovered and stolen by a camper named Henry Starling . Over the next thirty years , Starling would utilize his primitive understanding of the timeship ' s technology to introduce new computer innovations to the public , constructing a corporate empire and initiating the computer revolution of the 20th century . When " Voyager " arrived in Earth orbit in 1996 , they discovered Braxton living homeless on the street s of Los Angeles . Poor treatment at the hands of the 20th century authorities had left him paranoid and aggressive , blaming " Voyager " for his predicament . Braxton informed Captain Janeway of his deduction that , if Starling were to use the timeship to travel to the 29th century without properly recalibrating the ship ' s temporal matrix , then that could have been the cause of the temporal explosion which destroyed Earth ' s solar system . The crew of " Voyager " was able to prevent this future by destroying the " Aeon " with a manually - launched photon torpedo just before Starling entered the temporal rift , resulting in the creation of a new timeline in which the explosion never occurred . Shortly afterwards , " Voyager " encountered another temporal rift , created by Captain Braxton ' s counterpart from the new timeline . Having detected " Voyager " s anomalous presence in the 20th century , Braxton had traveled back in time to escort " Voyager " back to their proper place and time . Despite Janeway ' s plea to return them to Earth , as " Voyager " had been stranded in the Delta Quadrant for two years , Braxton insisted on upholding the Temporal Prime Directive . ( ) Sabotage . After his thirty - year exile on Earth , Braxton was forced to undergo extensive rehabilitation before he was allowed to return to duty as captain of the " Relativity " . In that capacity , he recruited Seven of Nine from the year 2375 to a mission to save " Voyager " from destruction . Bringing Seven aboard the " Relativity " , he explained that a saboteur had placed a temporal disruptor aboard " Voyager " , and that they needed her to identify the individual responsible and prevent the disruptor from destroying the ship . During the course of her investigation , Seven discovered that the saboteur was , in fact , Captain Braxton ' s counterpart from a future point in time . Braxton ' s counterpart explained that , in the upcoming few years of Braxton ' s life , he would be sent into rehabilitation again due to suffering from temporal psychosis , and subsequently forced to retire . Claiming Captain Janeway responsible for these events , due to the repairs he had to effect in response to the various time travel events in which " Voyager " was involved , including the temporal inversion in the Takara sector , he became determined to wipe " Voyager " from the timeline . Braxton ' s future counterpart attempted to convince Braxton to let him proceed and , in light of these revelations , Braxton ' s first officer , Lieutenant Ducane , placed Braxton under arrest for crimes he was going to commit , and took control of the mission . Ducane was eventually successful in apprehending Braxton ' s counterpart , but was still left with the task of repairing the damage done to the timeline due to Braxton ' s actions . As Seven could not make another time jump without suffering from temporal psychosis herself , Ducane recruited Captain Janeway to complete the mission . In exchange for leniency , Braxton ' s counterpart agreed to inform Ducane of the precise time and place where he planted the disruptor . Janeway was then sent to the year 2372 , where she was able to apprehend Braxton before he was able to activate the disruptor . This version of Braxton was subsequently transported back to the 29th century , resulting in the existence of no less than three versions of him being held in custody , although Ducane assured Janeway that all three of them would be reintegrated in time for him to stand trial .
