Early life

John Greene was born on Earth on 18 July 2334.

Starfleet history


John Greene was serving as first officer aboard the USS Robert Frost during the Federation-Tzenkethi War. (“The Tzenkethi Incident“)


Greene was posted aboard the USS Artemis when he was assigned to work with Special Ops operative Vanessa Biondo, who was based out of Starbase 294 at the time. Biondo‘s calm demeanor on the battlefield or during a mission, mixed with her cool reaction to crises, led him to pick her later as his choice for second officer aboard the USS Prospect in 2365. The two also had a brief yet intense romantic relationship during this time, broken off by the Artemis no longer being in the starbase’s region, with neither Greene nor Biondo willing to give up their career to be with the other. (“The Tzenkethi Incident“, “Love Song“)


John Greene was serving as first officer aboard the Artemis during the tail-end of the Federation-Cardassian War. Aboard the Artemis, Greene would become friends with Daniel Radke and Anne Lansing, amongst others.

Greene, aboard the Artemis, participated in the Battle of Ubessi in orbit of the neutral planet Ubessi. As a result of a Starfleet starship slamming into the planet’s surface, resulting in massive ecological destruction, he felt an obligation to return to the planet to assist the Ubessians. Weighing heavily on his conscience, Greene, with Lansing and Radke‘s help, convinced Artemis commanding officer James Ashenfelder to break battle lines and proceed to Ubessi to assist.

He led the away team, with Lansing and Radke present, to find only Yaghim Thau and a handful of his followers stripping the last remaining systems from a military bunker on the planet’s surface. Greene attempted to convince Thau to accept their assistance, but Thau instead threatened revenge for the destruction the Federation and Cardassians inflicted on his already civil war-ravaged (but recovering) planet.

After returning to the Artemis, they found Thau had a Galor-class warship under his command, and, with Cardassian forces also approaching, Ashenfelder ordered the Artemis to the safety of Federation-controlled space, despite the urging of Greene to continue to the Ubessians’ new planet to convince Thau to accept their assistance. (“What a Difference a Day Makes“)

The surviving Ubessians who settled on Bniikii eventually condemned Thau’s actions and elected Salua Harage leader. The Artemis returned to Bniikii to grant assistance. During this mission, Greene and Harage fell in love, and continued an on-again, off-again relationship until 2366. (“What a Difference a Day Makes“, “Stress Fractures“, “Love Song“)


In 2364, Captain Ashenfelder ordered the Artemis to return to Federation space after Radke‘s revelation of an alien conspiracy, Greene was a survivor when a then-unknown force sabotaged and attacked the Artemis, triggering a warp core breach alert. Several survivors, floating in escape pods, reported that Artemis appeared destroyed. (“False Security”)

Greene later admitted this event nearly caused him to quit Starfleet, or at least take a safe desk job. (“Lady Lazarus“)

2365: Before the Prospect

By 2365, Greene held the rank of captain. Sometime between the Artemis‘s destruction in 2364 and late 2365, he underwent another mission to Bniikii to make it a Federation protectorate at the request of Ubessian leader Salua Harage. It was during this time that they rekindled their relationship. (“Stress Fractures“, “Love Song“)

Aboard the Starship Prospect


In the last few months of 2365, he took command of the Special Operations starship USS Prospect, choosing Anne Lansing as his first officer, Daniel Radke as ship’s counselor and Vanessa Biondo as second officer, amongst others. Admiral Dorothy Franklin was responsible for the assignment, ordering Greene and the Prospect to investigate the disappearance of three Starfleet starships, including the USS Des Plaines. (“The Tzenkethi Incident“)


Greene and the Prospect team were assigned to help keep the peace during Federation-Cardassian peace talks in 2366. Responding to a distress call from a Federation colony, Greene found Yaghim Thau and his followers had intentionally orbital-bombed the colony with antimatter torpedoes, leaving one undetonated casing as a calling card. He ordered the Prospect to Bniikii to seek Salua Harage’s assistance, but his away team, led by Lansing, were surrounded by pro-Thau forces. With Thau’s fleet appearing in orbit, John Greene attempted to rescue the away team, succeeding in gaining back three members of the team, but having to retreat when Thau’s forces overpowered the Prospect. Lansing, Radke and Jennifer Drever were taken hostage. (“What a Difference a Day Makes“)


In late 2366 and early 2367, Greene pushed the Prospect to her limits in trying to arrive at Wolf 359 in time to face the Borg cube.

Admiral J.P. Hanson spoke with Greene with regards to the armada, and a horrified Greene witnessed audio communications from several starships at the Battle of Wolf 359, but by the time they arrived, the battle was finished. Within the starship graveyard, sensors detected a mysterious alien ship apparently communicating with the Borg cube. Greene ordered it pursued and disabled.

Despite his then-first officer Vanessa Biondo‘s objections, Greene led the away team to the alien ship. Under heavy fire, he ordered his team to surrender to that ship’s science officer T’Prain. Once face-to-face with the ship’s commanding officer Amila Thon, Greene learned various details about the future: his fight was not against the Borg; he’d go down in history; he would rescue prominent Starfleet officers from Wolf 359; Hahn Jun-Seok knew more than he let on, and wasn’t telling the truth about who he was; and so on. Thon returned Greene and his team to the Prospect to return to Wolf 359.

Once there, Greene oversaw and coordinated the rescue effort from the Prospect, including the discovery of the salvageable USS Endeavour. Near the end of the rescue mission, after taking Thon’s words to heart, he approved Biondo‘s and second officer Evonne Wilson‘s promotions to the full rank of Commander and transfers to the vacant first officer positions aboard the USS Arlington and USS Barrington respectively.

Thon reappeared to him to urge him to consider taking Lansing and Radke back aboard — a move he followed — and hinted to him that Kari Eriksson would complete the “rank on the chessboard” of players needed for his future fight. (“The Burnt Child“)

In mid-2367, Greene was still in command of the Prospect when, after repairs were complete, it relaunched from Utopia Planitia Fleet Yards. (“The Burnt Child“)

A few weeks later, he ordered an away team to infiltrate the city of Enika on Goffan III to determine whether the Jenchum Suzerainty was developing a subspace weapon while he and the Prospect orbited Goffan IV on a mission to improve sensors ability to detect molocine. While in orbit, he and Jenchum battle cruiser Alonia commanding officer Thelius debated on whether the Prospect‘s actions were legal, but Greene stood his ground, stating the Federation and Jenchum had sorted the details out.

When Eriksson went missing, Greene sent two away teams to attempt to extract her, the latter of which was successful.

He was also extremely embarrassed to discover Hahn Jun-Seok uncovered the Prospect‘s secret mission to the Jenchum, even though the desired result – discovery the subspace weapon test had been unsuccessful, and the Jenchum went back to developing conventional weapons – was reached. (“Starry, Starry Night“)

In late 2367, Greene was attending Hahn‘s birthday party when the Prospect received a distress call. Investigating it, the crew discovered the Artemis had not exploded in 2364 but jumped to warp and survived.

An uneasy Greene sent Daniel Radke, Anne Lansing, security chief George Stratos, Ensign Garrett, Ralf Mendoza and Steven Tedesco to the Artemis. Radke and his escort Garrett attempted to locate bodies, but were instead altered by the M’Tar. Transformed into the Liaison, Radke attempted to assist the M’Tar take control of the Federation, but a battle with undercover Na’arbi agent Hahn Jun-Seok spoiled that plan. Hahn severed Radke and Garrett from M’Tar control and transported them back to the Prospect before the Artemis exploded, dragging him and the two M’Tar into the M’Tar Domain, sealing the portal between the two dimensions.

Greene and Stratos investigated a strange energy pulse emanating from Hahn’s cabin to find a holographic transmission, warning Greene the M’Tar were growing in number and not near extinction. (“Lady Lazarus“)

Neither John Greene nor Starfleet revealed the true facts about the M’Tar to Daniel Radke as per his comments in Star Trek: The Cantabrian Expeditions episode “Catalyst, Part One“. It is assumed Starfleet was keeping this knowledge close to their chests for unknown reasons. The M’Tar is one of the “far worse” enemies Thon eluded to in “The Burnt Child”. Hahn being a Na’arbi agent was another such hint.


After the USS Odyssey‘s destruction by the Jem’Hadar in late 2370, Special Operations quickly assembled the Prospect crew and sent them from Deep Space 9 to the Gamma Quadrant to make first contact with the Founders. This mission failed, resulting in the Prospect‘s sacrifice in order to halt a Dominion incursion into Federation space. Captain Greene (the commanding officer), and the majority of the Prospect crew, survived on the saucer section, which coasted back through the Bajoran wormhole to Federation space. (“Pure Massacre“)

We assume John Greene was court-martialed but found not guilty for the Prospect‘s loss.

2371 / 2372

In 2371, the USS Prospect-A was launched with John Greene as her commanding officer. Greene wasn’t there at the commissioning ceremony, however, as the ceremony was held on Stardate 48650.6 and he took command on Stardate 48788.7. (“Home“)

On Stardate 48803.2, Greene and his crew investigated radio silence from the USS Venture. Upon arrival, Greene discovered an escaped El-Aurian, captured by the Venture crew a year earlier, wiped every single crew member from existence. Somehow the Prospect crew were protected from this, probably from a temporal barrier around the two ships. Greene and the El-Aurian fought, the former winning, and the Prospect returned him to Federation custody. (“The Road Not Taken“)

One of Greene’s greatest battles was against himself. On Stardate 48892.7, the Prospect senior officers’ mirror versions stormed the ship, attempting to hijack the ship. Greene, first officer Anne Lansing, and Greene’s brother chief engineer Michael Greene led non-essential personnel to safety and rescued the kidnapped personnel, also forcing the mirror senior crew back through the Iconian gateway they came through. (“Paradox“)

The Special Operations team, led by John Greene, responded to a distress call from Setlik III on Stardate 48939.4. Massive seismic disturbances threatened to destroy the planet, but further investigations found a massive weapon in the planet’s orbit, tapping energy from the planet, its weaponry focused on several Cardassian areas. Greene evacuated most crew members and colony survivors to the Prospect‘s saucer section and, with a skeleton crew, attempted to use the stardrive section to deflect any blasts while George Stratos attempted to stop the weapon before it triggered an interstellar incident. They were successful. (“Heritage“)

On Stardate 48994.8, Greene faced yet another of his most deadly enemies: Yaghim Thau. The Prospect battled Thau and his Breen mercenaries. To stave off the multiple attack, Greene ordered the ship separated, the battle so fierce Thau almost succeeded in forcing the saucer section to crash. Greene’s wit and training won, with Thau and his Breen crews crashing on the planet’s surface. The Prospect team took them into custody. (“Ramifications“)

The Prospect was sent, in 2372, to the Gamma Quadrant to find the USS Rutherford after it disappeared, and John Greene commanded this mission. Successful in discovering the Rutherford but unsure in the whereabouts of its crew, Greene ordered the Rutherford destroyed to stop it falling into Dominion hands. Battles with the Jem’Hadar saw the Prospect suffer heavy damage. (“Directive“)

Personal relationships


Anne Lansing

Anne Lansing and John Greene met aboard the USS Artemis around 2362. Greene being first officer and Lansing being second officer, the two worked together quite often on the bridge and their friendship grew from there. (“False Security”, “What a Difference a Day Makes“)

Greene requested Lansing as the USS Prospect‘s first officer in late 2365. (“The Tzenkethi Incident“) The first officer left, as did counselor Daniel Radke, after being held hostage for several weeks: a move Greene understood but was disturbed by. (“Parting“)

In mid-2367, he told Radke and Lansing he was glad to have them back aboard. He specifically requested Lansing reconsider serving aboard the Prospect as a result of Amila Thon’s advice. (“The Burnt Child“)

Later in the same year, when the Prospect crew received the Artemis‘s distress call, Greene admitted to Radke and Lansing, his two closest confidants, he considered giving up his career in Starfleet after the Artemis incident in 2364, and shared his deepest, darkest thoughts about the Artemis. Later in the same mission, after the M’Tar took over Radke‘s body and caused Lansing severe injuries, Greene felt both guilt at sending the team over. (“Lady Lazarus“)

Daniel Radke

John Greene and Daniel Radke met aboard the USS Artemis around 2362. Greene being first officer and Radke being counselor, the two worked together quite often on crew performance reviews and their friendship grew from there. (“False Security”, “What a Difference a Day Makes“)

Greene requested Radke as the USS Prospect‘s counselor in late 2365. (“The Tzenkethi Incident“) The counselor left, as did first officer Anne Lansing, after being held hostage for several weeks: a move Greene understood but was disturbed by. (“Parting”)

In mid-2367, he told Radke and Lansing he was glad to have them back aboard. He specifically requested Radke reconsider serving aboard the Prospect as a result of Amila Thon’s advice. (“The Burnt Child“)

Later in the same year, when the Prospect crew received the Artemis‘s distress call, Greene admitted to Radke and Anne Lansing, his two closest confidants, he considered giving up his career in Starfleet after the Artemis incident in 2364, and shared his deepest, darkest thoughts about the Artemis. Later in the same mission, after the M’Tar took over Radke‘s body, Greene felt both guilt at sending Radke over and vowed to get Radke back at almost any cost. (“Lady Lazarus“)

In 2371, Greene missed the Prospect-A’s launch and maiden flight, which ended up as a rather eventful affair. John Greene expressed to Radke (who was present) when he took command that he’d hoped Radke and the others hadn’t roughed up his ship too much. (“Home“)


Vanessa Biondo

Greene and Biondo met around 2361 when the Artemis was assigned to Starbase 294 as a home base. They had a brief but intense relationship, only ending due to the Artemis moving on and the unwillingness of either Greene or Biondo to give up their posting for the relationship. (“The Tzenkethi Incident“, “Love Song“)

With the ability to pick his own crew, Greene chose Biondo as his second officer aboard the Prospect in late 2365 due to her sheer brilliant technical skills and remarkable ability to stay calm and act effectively under severe pressure. In addition, her empathy and humanity in dealing with others made her a stand-out choice for his second officer. When he requested her, she felt their past relationship could get in the way of their working relationship. (“The Tzenkethi Incident“)

When Biondo stepped up to the position of acting first officer after Anne Lansing‘s kidnapping by Yaghim Thau in 2366, the tension between the two rose. (“Stress Fractures“) Once Lansing was rescued but decided to leave the Prospect, Greene promoted Biondo to first officer permanently. (“Parting“)

Vanessa Biondo was a bit surprised at John Greene’s relationship with Salua Harage in light of him starting it so soon after he and Biondo had split up. (“Stress Fractures“, “Love Song“)

While Biondo stepped in after the death of Harage in an attempt to give Greene a little time to grieve, she also took the time to console him. (“One Step Forward, Two Steps Back“) Ultimately, both he and she realized their serving aboard the same ship would not work, and, taking the advice of Amila Thon on board, Greene took the liberty of granting Biondo‘s somewhat cryptic request to be transferred. After the Battle of Wolf 359, the USS Arlington needed a new first officer, and John Greene highly recommended Vanessa Biondo for the job, earning her a promotion. (“Children of the Revolution“, “The Burnt Child“)

Salua Harage

Greene met Salua Harage on Bniikii around 2362 when the Federation was attempting to assist the Ubessians settle on their new home world. It was during this time that Greene and Harage started up an on-again, off-again relationship that would last until 2366. (“What a Difference a Day Makes“, “Stress Fractures“, “Love Song“)

Harage convinced Greene to allow her on board the Prospect to help convince the Cardassians that Yaghim Thau and his followers were not sanctioned by Bniikii or the Ubessians. As the leader of a Federation protectorate, Harage attempted to mediate a peace with the Cardassians and help them track down Thau and his followers. It was during this time that Greene and Harage continued their relationship. (“Stress Fractures“, “The Forbidden“, “Parting“, “Love Song“)

Greene and Harage met with Gul Ekar to formalize a peace agreement, but Ekar gunned Harage down in cold blood while Cardassian forces attacked Bniikii. Aboard the Prospect, Harage died in Greene’s arms despite Dr. Justin O’Donovan‘s best efforts to save her. (“One Step Forward, Two Steps Back“)

Enraged by her death, Greene took the Prospect to hunt down Thau to bring him to justice, although the final battle between the two saw Thau defeated but captured by the Cardassians for trial. He was somewhat heartened by Harage’s proteges stepping up to lead the survivors on Bniikii in her memory. (“Children of the Revolution“)
