He was later dismissed by Pike at 0500 after YeomanColt entered the bridge while the ship was en route to Talos IV.
He had returned to the bridge and was present when the Talosians disabled the ship in orbit, after haven taken Pike, Colt and Number One captive. He was conversing with the crewman posted at the turbolift door when the Talosians accessed the ship's library computer, at which point he ran over to the engineering station.
Following the return of Pike and crew, he took Number One's jacket and utility belt from her as she entered the bridge. In the moments that followed, he returned to the captain's side with a clipboard as the ship departed Talos. (TOS: "The Cage")
In this crewman's initial appearance, he apparently served in the capacity of security as he was the only other crewperson observed wearing the division insignia, same as the crewman stationed by the elevator. In spite of these observations, his actions when summarized most resembled that of a yeoman's role, in that he was often held a clipboard, delivered documents to the captain, was dismissed upon the arrival of Colt, and took articles from the command crew as they entered the bridge from the elevator.
When Captain Pike decided to continue on to Vega colony and left the bridge, he exchanged shrugs with the crewman posted next to Pike's command chair.
He was still present on the bridge when the Talosians disabled the ship in orbit, after haven taken Pike, Colt and Number One captive. He was conversing with the crewman posted at Pike's command chair when the Talosians accessed the ship's library computer, at which point he ran over to the communications station.
This crewperson appeared to serve in the capacity of security (as seen depicted by operations personnel throughout TOS occupying this location) and was the only other crewperson, aside from the man next to the captain's chair, to be visually verified as wearing the unique badge insignia (an arrowhead with a "C"-shape).
He was named Valdini in the novel The Rift and was one of many officers that perished on Argus X in 2268.
These two crewmembers were seen by Captain Pike on a corridor in 2254. They were wearing civilian outfits. (TOS: "The Cage")
In the second revised final draft script of "The Cage", these crewmembers are referred to as "a casually dressed Young Man and Young Lady intent on each other, obviously headed for a ship's recreation area."
Later that year, he was doing maintenance work with a sciences technician on a corridor, where he was passed by the M-113 creature posing as CrewmanGreen. He was wearing a beige technician jumpsuit at that time. (TOS: "The Man Trap")
The same year, he was also present in the recreation room, when Uhura introduced tribbles to her crewmates, and when the tribble-infested recreation room, when Kirk and Spock visited it, to have lunch. He was later assigned to keep order among the shore leave participants when the ship visited Deep Space Station K-7. Instead, he participated in the bar fight between the Enterprise crew and the IKS Gr'oth personnel. He was confined to his quarters afterwards. (TOS: "The Trouble with Tribbles"; DS9: "Trials and Tribble-ations")
He was among the honor guard, greeting AmbassadorSarek on the Enterprise, the same year. Later, he served as relief navigator (wearing a gold command uniform) when the Orion scout ship attacked the Enterprise. (TOS: "Journey to Babel")
He accompanied Captain Kirk to EnsignGarrovick's quarters when Spock was attacked by the dikironium cloud creature inside, the same year. (TOS: "Obsession")
He was present on the bridge when the Enterprise encountered a giant single cell lifeform, the same year. (TOS: "The Immunity Syndrome")
The same year, he was present in main engineering, and was placed in "frozen" and motionless stasis by Tomar as the Kelvans attempted to hijack the Enterprise and take it to the Andromeda Galaxy. A short time later, he would have been considered one of many non-essential personnel and the Kelvans would have neutralized and reduced him into a dehydrated porous cuboctahedron solid, the size of a Human fist, composed of his base minerals which represented the "distilled" essence of his being. He would have been reconstituted after the four commanding officers, not neutralized, regained control of the ship. (TOS: "By Any Other Name")
Still the same year, he was called to the bridge (again, with Lemli) to arrest the intruder Kara, soon before she rendered the entire crew unconscious. Later, he was also a member of the away team on Sigma Draconis VI, and remained on the surface with EnsignChekov and another security guard, to keep contact with the ship. (TOS: "Spock's Brain")
Still the same year, he participated in the fights between the Enterprise crew and Kang's Klingon personnel, under the influence of the Beta XII-A entity. During the events, he escorted an injured security guard to sickbay. (TOS: "Day of the Dove")
She was present in the recreation room (albeit wearing a blue sciences uniform), when Lazarus visited the Enterprise, the same year. She was also present on the bridge sometime earlier. (TOS: "The Alternative Factor")
This crew woman was infected by the spores of Omicron Ceti III and transported down to join the colony on the planet in 2267. After she recovered, she was present on the bridge when the Enterprise left the planet. (TOS: "This Side of Paradise")
She was also on the bridge when the Enterprise found the destroyed USS Constellation, the same year and later she was on the bridge when Spock signed a report after encountering the Planet Killer. She was wearing a blue sciences uniform that time. (TOS: "The Doomsday Machine")
This crew woman was present on the hearing assembled by CommodoreStocker to determine if Captain Kirk, suffering from rapid aging, was capable of commanding the Enterprise. She served as recorder on the hearing, in 2267. (TOS: "The Deadly Years")
The same year, she was present on the bridge, handing a report to CommodoreMatt Decker when the Enterprise encountered the Planet killer. Earlier, she was present on the bridge when the Enterprise went to red alert upon discovering the USS Constellation.(TOS: "The Doomsday Machine")
He was also present in the recreation room when Lazarus visited the Enterprise, the same year. Somewhat later, he was also present on the bridge (this time wearing a red operations division uniform). (TOS: "The Alternative Factor")
This lieutenant was guarding the bridge near the turbolift door, when the Enterprise discovered the remains of the USS Constellation in 2267. (TOS: "The Doomsday Machine")
In 2268, he participated in the fight between the Enterprise crewmembers and the Klingon personnel of IKS Gro'th on Deep Space Station K-7. Later he was interrogated by Captain Kirk. After he was released from quarters confinement, he was present in the recreation room, visited by Kirk and Spock. He was wearing a blue sciences uniform during these events. (TOS: "The Trouble with Tribbles"; DS9: "Trials and Tribble-ations")
The same year, he was present at the captain's memorial service, when Kirk was presumed dead on the USS Defiant. He was wearing a gold command uniform that time. (TOS: "The Tholian Web")
These Starfleet crewmembers attended the briefing on the recreation deck of the USS Enterprise in the 2270s. They were witnesses to the destruction of the Epsilon IX station during the briefing. (Star Trek: The Motion Picture)
All 170 crewmembers were played by extras, production staff members, and fans and most of them received no on-screen credit for their appearances. They were cast by a cattle call, organized by Bjo Trimble and had to fullfill these special requests: "aged between 20 and 40, men from 5'8" to 6'2", sizes 40-42, and women from 5'6" to 5'8', sizes 8-10."
This transporter accident victim and Sonak were killed in a transporteraccident shortly before the starship left to deal with the V'ger crisis in the mid-2270s. The ship's transporter was 'temporarily' out of order that time; Janice Rand operated the transporter when she saw their silhouettes being deformed, and despite Kirk's attempts to complete the transfer, they disappeared. When Kirk asked Starfleet if they ended up with their disfigured masses, a transporter operator at Starfleet Headquarters said what he saw were fortunate that they didn't live long.
