Star Trek: The Next Generation season 3 is when the series truly began firing on all cylinders. After some shuffling around of writers and characters throughout TNG seasons 1 and 2, everyone had finally found their place by the show's third season. The actors felt more in tune with their characters, and the writers seemed more confident in writing for those characters. While TNG's first two seasons had highs and lows, Star Trek: The Next Generation season 3 (and several of the subsequent seasons) consistently delivered hit after hit.

greatest sci-fi shows of all time, thanks to its 10 best episodes.

10 "Tin Man"

Star Trek: The Next Generation Season 3, Episode 20

When Starfleet discovers a strange new alien lifeform later known as Gomtuu, they send Betazoid emissary Tam Elbrun (Harry Groener) to attempt to communicate with it. Thanks to his extremely powerful telepathic abilities, Elbrun begins talking with Gomtuu, forming a quick connection with the living ship. Gomtuu interests the Romulans as well, who intend to destroy it if they cannot find a way to communicate with it.

Screenwriters Dennis Putman Bailey and David Bischoff wrote "Tin Man" after being disappointed by TNG season 2's "Samaritan Snare" and deciding they could pen a better episode.

In the end, Elbrun saves Gomtuu and departs with it, finally finding peace away from the cacophony of thoughts he normally hears. Harry Groener's strong performance makes Elbun a fascinating guest star, and the episode is smart to pair him with Brent Spiner's Lt. Commander Data. "Tin Man" may not be a revolutionary episode of Star Trek, but it delivers a classic story well, and Gomtuu makes for a unique alien-of-the-week.

9 "The Most Toys"

Star Trek: The Next Generation Season 3, Episode 22

In this Data-focused episode, a trader named Kivas Fajo (Saul Rubinek) kidnaps Data, wanting to add the one-of-a-kind android to his collection. Fajo fakes Data's death, ensuring that Captain Picard and his crew do not immediately begin searching for him. Data resists Fajo however he can, until the contemptible collector threatens to kill one of his assistants if Data does not comply

Eventually, Data's friends on the Enterprise realize that the facts about his supposed death don't make sense, and they go back for him. After Fajo kills his assistant, Data points a phaser at Fajo, contemplating whether to kill him. Just as the Enterprise beams Data back, the android appears to fire his weapon, even though his programming shouldn't allow this. Saul Rubinek makes Fajo a particularly memorable guest star, and "The Most Toys" offers a fascinating exploration of Data's character.

8 "The Enemy"

Star Trek: The Next Generation Season 3, Episode 7

Lt. Commander Geordi La Forge (LeVar Burton) stars in back-to-back episodes, fairing far better in his second outing than in the first.

Despite being enemies, the two must work together to survive as the planet's environment wreaks havoc on their bodies.

Meanwhile, on the Enterprise-D, Lt. Worf (Michael Dorn) refuses to save a dying Romulan, despite being the only suitable donor.

Geordi is at his most likable in "The Enemy," as he sarcastically reacts to Bochra's attempts to hold him prisoner. In the end, Geordi proves why he's Chief Engineer on the Federation flagship, as he and Bochra come up with creative solutions to locate the beacon left by the Enterprise crew. The episode's ultimate message about tolerance is a good one, and the story offers fascinating insights into several of the show's characters.

7 "The Defector"

Star Trek: The Next Generation Season 3, Episode 10

Captain Picard and his crew are skeptical when they rescue a Romulan named Jarok (James Sloyan), who claims to be a defector.

Jarok wishes to protect his wife and child from an impending war, and Picard eventually comes to believe the Romulan iral.

However, upon finding no secret Romulan base, Jarok realizes that the Romulans fed him false information to lure the Enterprise into a trap. Thankfully, Picard had anticipated this and came accompanied by three Klingon Birds-of-Prey. Tragically, Jarok then takes his own life, knowing that he can never return to his family. "The Defector" is a powerful episode that helps define the Romulans of the TNG era.

6 "Deja Q"

Star Trek: The Next Generation Season 3, Episode 13

When the Q Continuum strips Q (John de Lancie) of his god-like powers, he arrives on the Enterprise-D seeking asylum. Now familiar with Q's antics, Captain Picard and his crew are understandably skeptical of Q's claims. Picard assigns Data to keep an eye on Q, and their interactions prove that Star Trek: The Next Generation should have paired Data and Q more often.

When one of Q's old enemies attacks the Enterprise, Data is electrocuted fending them off. Q is genuinely affected by Data's act of self-sacrifice, prompting the formerly omnipotent being to leave the Enterprise on a shuttlecraft in an attempt to draw his enemies away. This selfless act impresses the Q Continuum enough that they return Q's powers, after which he grants Data a moment of genuine laughter as a thank you.

5 "Sins Of The Father"

Star Trek: The Next Generation Season 3, Episode 17

Although the Klingons were introduced back in Star Trek: The Original Series season 1, their home planet of Qo'noS was not shown on screen until 1990's "Sins of the Father," which a great introduction not only to the Klingon homeworld but also to the shifting Klingon politics of TNG's 24th century era. The story begins when Worf's brother, Kurn (Tony Todd), shows up on the Enterprise as part of the officer exchange program.

Kurn informs Worf that their family's honor is being called into question, and Worf convinces Captain Picard to take the Enterprise to Qo'noS.

"Sins of the Father" is an incredibly strong episode that teaches Worf the hard lesson that not all Klingons value honor as highly as he does.

4 "Sarek"

Star Trek: The Next Generation Season 3, Episode 23

Gene Roddenberry initially did not want Star Trek: The Next Generation to reference Star Trek: The Original Series, but he began to soften to the idea over time. While Ambassador Spock (Leonard Nimoy) himself will make an appearance in TNG season 5, it's his father, Ambassador Sarek (Mark Lenard), who gets the spotlight in season 3. Soon after Sarek boards the Enterprise for an important conference, the ship's crew begins experiencing odd emotional outbursts.

While Mark Lenard is most ed for portraying Sarek, he also appeared as a Romulan Commander in "Balance of Terror" and a Klingon Captain in Star Trek: The Motion Picture.

Dr. Beverly Crusher (Gates McFadden) eventually discovers that Sarek is suffering from a Vulcan neurological disease known as Bendii syndrome. In order to maintain his composure during the conference, Sarek agrees to mind meld with Captain Picard, allowing the Enterprise captain to take on Sarek's strongest emotions. Mark Lenard and Patrick Stewart both deliver powerful performances throughout the episode, with the mind meld scene being a particular highlight.

3 "The Offspring"

Star Trek: The Next Generation Season 3, Episode 23

In another stand-out episode for everyone's favorite android, Data decides to create an android daughter for himself named Lal (Hallie Todd). After allowing Lal to choose her own gender and appearance, Data spends the rest of the episode teaching Lal how to be human, with hilarious and heartwarming results. When Lal's programming begins to sur Data's, she experiences a cascade failure that even Data cannot repair.

"The Offspring" was the directorial debut of Jonathan Frakes, who has since become one of the franchise's most beloved and prolific directors.

In one of Star Trek's saddest endings, Lal dies despite everything Data does to save her. Data preserves her memories within his own positronic brain, ensuring that she lives on in some way. After watching "The Offspring," it's impossible to deny that Data experiences feelings of some kind, regardless of his protests otherwise. Nearly everything about the episode works, thanks in large part to stellar performances from Brent Spiner and Hallie Todd.

Star Trek: The Next Generation Season 3, Episode 15

When the USS Enterprise-D encounters the USS Enterprise-C emerging from a rift in spacetime, the entire future of the Federation is altered.

As the Enterprise-D works to repair the C, Yar develops a connection with the ship's helmsman, Lt. Richard Castillo (Christopher McDonald).

Captain Picard eventually convinces Captain Rachel Garrett (Tricia O'Neil) that she has to return through the rift with the Enterprise-C even if it means certain death. The sacrifice of Garrett and her crew will prevent a war with the Klingons that has cost billions of lives. It's a great premise executed brilliantly that not only gives viewers the chance to see Yar again but also reveals more about the history of ships named Enterprise.
