Character Bio

Lieutenant Hadley photo
Hadley was a Starfleet officer aboard the Federation starship Enterprise between 2266 and 2269 during Captain Kirk's five-year mission. He was a shift navigator and helmsman, but also served on security detachments aboard that ship. When assigned to the bridge, he usually wore a command division gold uniform.

Hadley was referred to as "lieutenant" on multiple occasions, but sometimes he wore an ensign's uniform (no insignia). His gold costume included the full lieutenant braid up until TOS Season 3. It might be possible he was a lieutenant junior grade in the anomalous appearances, as this situation occurred with several other lieutenants in TOS, but speculation also exists the officer might have been demoted or only temporarily promoted.

He assisted Chief Engineer Scott when the Enterprise was trying to break away from planet Psi 2000 in 2266.

In security red uniform, he was involved in the search for Lazarus.

Hadley was on the bridge when Khan Noonien Singh took over the Enterprise in 2267; he passed out after the life support to the bridge was cut, and was seated in a prisoner's row with Lt. Leslie, Brent and others, forced to watch Khan's murderous spectacle on the viewscreen.

Brent, Leslie and Hadley were not mentioned as receiving commendations like Uhura, Thule and Harrison, Spinelli and Spock.
It is possible Kirk ran out of air before being able to list the entire bridge crew.

Hadley was wearing a red operations division uniform, serving on a security team ordered by Lieutenant Commander Giotto to hunt for the Horta, on Janus VI.

Scott relied on Hadley to look up the meaning of the word heater in the ship's language banks. This was the only occasion in which Hadley was referred to by name.

During the Kelvan takeover of the Enterprise, Hadley was transformed into a crystal form, but was later restored when control was regained.

When Daystrom suffered a nervous breakdown Hadley and Leslie took him off the bridge.

In late 2268, Hadley was present on the bridge during the hunt for Spock's stolen brain. Trivia Hadley began wearing no rank insignia in this episode.

Hadley enjoyed socializing with visitors aboard the ship, like Ambassador Petri of Troyius who was sent to educate Elaan the Dohlman of Elas in things Troyan and how she should behave.
