Hogan Hogan was an engineer who initially served as a member of a Maquis crew which operated the " Val Jean " , a Maquis raider under the command of Chakotay . After that craft became stranded in the Delta Quadrant in 2371 , Hogan worked as a crewman aboard the Federation starship , where he collaborated not only with his Maquis compatriots but also with the ship ' s Starfleet crew members . He was meanwhile assigned to engineering with the provisional rank of ensign . Hogan was a close friend of ex - Maquis Michael Jonas and Kurt Bendera . However , like many of the Maquis , Hogan was at first unsparing in his criticism of Captain Kathryn Janeway , " Voyager " s commanding officer . History . After Bendera ' s funeral in 2372 , Hogan suggested handing over transporter and replicator technology to the Kazon in violation of the Prime Directive . He believed doing so would give " Voyager " better security as it made passage back to the Alpha Quadrant . Following the collapse of peace overtures with the Kazon - Nistrim , Hogan tried to convince B ' Elanna Torres , " Voyager " s chief engineer , to discreetly contact Seska , a former member of " Voyager " s crew who had since allied herself with the Kazon , but Torres was loyal to Captain Janeway and distrustful of Seska . Hogan was unknowingly responsible for giving Jonas the idea of becoming a spy for Seska . ( ) When " Voyager " s warp drive became dysfunctional shortly thereafter , Hogan was part of an engineering team which tried to determine what the problem with it was . He reported directly to Torres that their efforts to restart the warp drive hadn ' t yet been successful but that the cause had been narrowed down to some kind of issue with a specific EPS conduit aboard the vessel . He also relayed to Torres that Ensign Lon Suder had reported no evidence of the problem during the previous day . The malfunction turned out to be one of the first signs that Suder had murder ed Crewman Frank Darwin . ( ) Hogan was later ordered by Torres to help Neelix investigate deletions from the ship ' s subspace log s , as Neelix suspected that whomever had erased the missing log entries had been spying on " Voyager " for the Kazon . ( ) Ironically , despite having inadvertently given Jonas the idea to do exactly that , Hogan assisted Neelix with the investigation . ( ) He made an unsuccessful attempt to recover the logs , though he did manage to determine how the messages had been secretly sent , and indirectly led Neelix to discover the messages were part of an effort by the spy to falsely implicate Tom Paris in collaboration with the Kazon . Privately , Commander Chakotay wondered if the spy might really be Hogan , though Neelix was doubtful of this , given that Hogan had simply been walking by when Torres had asked him to assist . While subsequently helping prepare for the engineering staff to rebuild the warp coil s , Hogan learned from Neelix , much to Hogan ' s surprise , that Paris was innocent of having sent the messages but , because Hogan and his co - workers were very busy , he was reluctant to lend Neelix further assistance . He left Engineering in compliance with an instruction from Jonas to take some engineering data to Torres . His departure allowed Jonas , who was finally identified as the spy , to confine and then attack Neelix , though Jonas himself died soon afterwards . ( ) Hogan was severely injured while repairing damage on Deck 15 , shortly after " Voyager " was duplicated by a spatial scission . When Kes arrived with a medkit , Hogan and Torres saw her be suddenly transported to the duplicate " Voyager " . Hogan was then helped to safety by Torres . A duplicate of Hogan was aboard the other " Voyager " , who likewise assisted a duplicate of Torres in their Engineering department . ( ) Hogan was manning the transporter console on " Voyager " when the crew encountered some trouble with the ship ' s transporter . He was made responsible for beaming Tuvok and Neelix back aboard the ship , an operation that was somewhat delayed due to the technological problem . Though Hogan expected he had managed to fix it , he detected an issue during transport that resulted in the creation of Tuvix who , as Hogan pointed out , was basically a merging of the two transport subjects . A type of orchid , which used symbiogenesis for procreation , had also become caught up in the beaming and was actually responsible for having caused the transporter accident . A short time later , Hogan was one of several officers who frantically struggled to make dinner for themselves in the kitchen area of the ship ' s mess hall , since Neelix was absent . As such , Hogan was tasked by Ensign Swinn with flipping some egg s she was cooking , because they were burning , but Tuvix soon arrived and resolved the chaotic situation by taking control and moving everyone else out of the kitchen . Tuvix was later divided into his separate components . ( ) When Captain Janeway and Commander Chakotay were infected by a virus which confined them to a planet dubbed " New Earth , " Hogan heard news that Ensign Harry Kim had desperately tried , on the bridge , to convince Tuvok to seek medical aid from the Vidiian s , which would violate orders from Janeway , but that Kim had consequently been relieved of duty . Together with Swinn , Hogan confronted Kim in the mess hall and supported his idea , also saying there were many who agreed with them . Hogan later stood among a group of such officers on the bridge when Tuvok voiced a speech in which he declared he would indeed contact the Vidiians , although following this course of action brought " Voyager " into combat with a fleet of Vidiian ships . As the battle raged , Hogan was again in engineering . The crew ultimately procured an antiviral serum from Danara Pel , a Vidiian ally of theirs , who was aboard one of the Vidiian ships , before " Voyager " managed to escape and then rescue Janeway and Chakotay . ( ) Hogan ' s career on " Voyager " came to an end when the majority of the crew were marooned on Hanon IV by the Kazon - Nistrim . ( ) He showed Neelix a system of cave s on the planet , remarking that they seemed as if they had been constructed , and theorized that a native population on the planet may have created it . When Neelix suggested to Hogan that he gather some humanoid - looking bone s near the mouth of the cave network , Hogan was momentarily hesitant but then decided to start collecting all the bones . Moments later , he was , however , suddenly attacked , dragged into the caves and killed , screaming , by an Hanonian land eel , leaving merely scraps of his uniform behind . Neelix felt guilty for the loss of Hogan , though Janeway immediately dismissed this sentiment . She called Hogan " a fine officer and a good man , " and vowed that his death would be the last on that planet for at least a long while . The cloth remnants of Hogan ' s uniform were used by Chakotay to make solar still s . ( ) The same year , Hogan ' s remains were excavated by a Voth scientist called Forra Gegen . Gegen found significant gene tic similarities between Hogan and the Voth and believed that this was evidence to support a hypothesis called Distant Origin Theory . The remains were taken to the Voth city ship . ( ) Appendices . Background information . Hogan was played by Simon Billig . He was initially called with an invitation to try out for the part a week after unsuccessfully auditioning for a Klingon role in . Since he had already auditioned for the casting director of DS9 , Billig was called directly in to meet the producers of . " " My audition [ for Hogan ] was actually the two scenes from the first episode that I was in , " " Billig stated . However , the pair of scenes included a lot of technobabble . " " So , I came across a couple of those words and sort of faltered at them the first time I read the scenes , " " the actor continued . " " I told the producers that maybe the second time I read I ' d remember transducers or something and I got a laugh out of that . I did the scenes and after talking a bit they said , ' Well , can you do them again and make this sort of slight adjustment ? ' which I did . It was the kind of audition that made me feel everything sort of clicked and came together in a very positive way . I felt really good about it when I left and then I wound up getting a call from them that same day offering me the part . " " ( " TV Zone " , Issue 93 , p . 30 ) Concerning Billig ' s casting as Hogan , Executive Producer Jeri Taylor recalled , " " We needed someone to do a small part in , and so we hired this young man . " " ( ) Simon Billig regarded Hogan as somewhat of a devil ' s advocate and someone unafraid to express his own opinion , especially when he thought it would benefit " Voyager " and its crew . " " He might seem to be a bit of an upstart , " " Billig observed , " " but he genuinely believes that when he does something it ' s not just for his good but for the good of everyone else , too . Most of the significant scenes I had revolved around my trying to do something that I feel is right and vital to " Voyager " even though it might clash with what the captain or any of her officers think . So , I guess Hogan ' s a bit of a crapstirrer , " " the actor chuckled , " " but with good intentions . " " ( " TV Zone " , Issue 93 , p . 30 ) The reaction of " Star Trek : Voyager " s producers to Simon Billig resulted in the recurring nature of Hogan ' s appearances . Jeri Taylor offered , " " Well , this is one of those lucky breaks that happens for an actor [ . . . ] [ Billig ] really turned out to be a very nice actor . So we just kept using him as a convenience ; it ' s always nice to have somebody else to talk to in Engineering besides B ' Elanna . And he ' s turned out to do a nice job , and so he ' s lucked into a great deal of work that way . I can ' t say that he ' s going to be a regular or anything like that [ . . . ] He just turns out to be sort of a convenience for us . " " Another factor in making Hogan a recurring character was that it helped to illustrate how limited the " Voyager " crew was . ( ) Following his work on , Simon Billig was notified by the VOY producers that Hogan was going to be a recurring character in the series . The actor enjoyed playing Hogan in such episodes as " Alliances " , , and . He cited Hogan as one of the most challenging and rewarding characters he ever portrayed , though also believed the task became gradually easier . " " As I ' ve done more and more episodes I ' ve become much more relaxed and confident about what I ' m doing , " " he explained . Billig made a point of watching the installments that included his performances as Hogan , when they first aired . " " It ' s also a thrill for me to sit and watch an episode of " Voyager " and go , ' Yes ! That ' s what I wanted . I got exactly what I wanted to out of that scene , " " he related . ( " TV Zone " , Issue 93 , p . 32 ) The producers ' realization that Hogan was a convenient character for them to utilize led them to create the character of Ensign Swinn , who was initially intended to be a similar recurring character , although this did not come to pass . ( ) Hogan ' s rank was unclear ; it appeared to be that of crewman , as he was referenced in " Alliances " and , but he was called " ensign " in and " lieutenant " in . However , the fragments of uniform found with his remains in clearly show the rank insignia of a provisional ensign .
