Star Trek: Enterprise first aired in 2001, designed as a back-to-basics character-driven prequel to Star Trek: The Original Series. Picking up many of the franchise's original themes and core values, Star Trek: Enterprise's best episodes explore the origins and moral ambiguities of such topics, simultaneously addressing ethical dilemmas and assumptions while granting greater depth and access to the different characters. Set in the 22nd century, the series introduces a previously unseen and untested crew and follows their adventures as they set off into the vast, very much unknown.

Casting Captain Jonathan Archer (Scott Bakula) as a flawed yet approachable starship commander with a history of piloting experimental warp technology, Star Trek: Enterprise establishes an intimate yet casual atmosphere that contrasts the gritty hostility of space and allows for immediate connection with its main characters. When the Enterprise NX-01, Starfleet's first Warp 5 starship capable of deep space exploration, launches ahead of schedule, lesser in crew numbers and ship size than in any previous series, Enterprise's premiere episode that pits prejudices with first s and establishes its role among the stars. Here are the 20 best episodes of Star Trek: Enterprise.

20 "Broken Bow" (Enterprise Season 1, Episodes 1 & 2)

Star Trek: Enterprise's premiere introduces Captain Jonathan Archer, Subcommander T'Pol (Jolene Blalock), and the crew of the Enterprise NX-01. Kicking off with United Earth's First with the Klingons, "Broken Bow" delivers a pace that offers the unexpected against an inexperienced crew with inferior technology and fewer space-smarts than other Star Trek series. Though the series took a while to find its place in the franchise, this first episode is a gritty, adventure-laden first step into the great beyond, although it's also widely ed for introducing the sexually charged elements - the decontamination scene - that would become synonymous with Enterprise's 4-season run.

19 "Vox Sola" (Enterprise Season 1, Episode 21)

"Vox Sola" is a fascinating study of the "seek out new life" clause in Starfleet's Captain's Oath. The episode begins with a failure in communication and an unrealized cultural taboo while a second undiscovered species finds its way aboard. Craving connection, the symbiotic lifeform ensnares four crew. Paving the way for Star Trek's first musical episode, the creature's language combines musical notes and mathematical formulas. It's a pleasant return to Star Trek's awed curiosity at the unknown.

18 "Detained" (Enterprise Season 1, Episode 21)

Notable as the episode that reunited Scott Bakula with Dean Stockwell from Quantum Leap, "Detained" is a dark allegory on prejudice. When Archer and Travis Mayweather (Anthony Montgomery) wake up in a Tandaran internment camp, they are told that they'll face a magistrate by the morally complex Colonel Grat (Dean Stockwell). With the Enterprise out of , this episode holds a mirror to discrimination across multiple levels.

17 "Regeneration" (Enterprise Season 2, Episode 23)

Archer and his crew must stop the Borg after cybernetic remnants from events in Star Trek: First are discovered buried in the Arctic and inadvertently reactivated. As Borg nanites begin to assimilate Doctor Phlox (John Billingsley) on Enterprise, it's a race against time and an uphill battle against incessant, adaptive technology from 200 years into the future. Altering Star Trek: The Next Generation history, this episode offers a genuinely tense experience through the Enterprise crew's naivety of the insidious threat later posed by the Borg, and from the transmission to their collective with Earth's coordinates.

16 "Proving Ground" (Enterprise Season 3, Episode 13)

With Enterprise hampered by the loss of navigational data, it's an uncertain and potentially deadly trek through the Delphic Expanse's spatial anomalies. Heavily damaged by a dangerous vortex, the Enterprise escapes with assistance from Andorian Commander Shran (Jeffrey Combs). The episode is an excellent delve into themes of characterization and motive, twisting a web of righteous agenda to push against tenuous trust. In a test of nerve vaguely reminiscent of Captain Kirk's Corbomite maneuver, Archer threatens to trigger the Xindi weapon's detonation sequence.

15 "The Andorian Incident" (Enterprise Season 1, Episode 7)

An impromptu visit to the sacred P'Jem Vulcan monastery goes awry in one of Star Trek: Enterprise's most significant first-season episodes. Directed by Star Trek: Voyager's Roxann Dawson, "The Andorian Incident" introduces the antagonistic relationship between Andorians and Vulcans, and makes the Andorians truly matter for the first time since their introduction in Star Trek: The Original Series. "The Andorian Incident" debuts the charismatic Commander Shran, whose suspicions about the Vulcans' actions are confirmed when the monastery is exposed as concealing a covert surveillance post.

14 "Similitude" (Enterprise Season 3, Episode 10)

"Similitude" offers a sociologically relevant and thought-provoking examination of ethics and ability. When Commander Trip Tucker (Connor Trinneer) is severely injured, Archer and Phlox embark on a morally questionable plan to save him - a mimetic symbiote as a neurological donor. The procedure will kill the donor, named Sim, who may be able to extend his own life through experimental surgery. The uncomfortable scenario is somewhat reminiscent of Star Trek: Voyager season 2, episode 24 "Tuvix," balancing the idea of 'the greater good' against humanist values.

13 "The Augments" (Enterprise Season 4, Episode 6)

The final episode of a three-part story that draws inspiration from Star Trek's previous encounters with augmented humans. "The Augments" indirectly compares Khan Noonien Singh (Ricardo Montalban) with its genetically engineered group, each with an aggressive bent and focus on supremacy. Notable for reuniting Star Trek: The Next Generation actors LeVar Burton and Brent Spiner as director and guest star, respectively, the episode leaps from deadly exposure to pathogens and open space, to attempted genocide and instigated war, to mutiny, vengeance, and murder.

12 "Stratagem" (Enterprise Season 3, Episode 14)

A careful series of ruses play out in "Stratagem," which opens with Archer and Degra (Randy Oglesby), a Xindi Council member, both haggard and exhausted. This Enterprise episode is a powerful character study of two rivals confined together, seemingly three years into the future. Degra struggles with a missing memory and suspicions about the validity of his friend's explanations, and it's a cautious balance between cooperation and distrust from both parties. Meanwhile, Archer cautiously delves for the information that might save Earth.

11 "Damage" (Enterprise Season 3, Episode 19)

With Earth at risk of destruction, the Enterprise falls victim to a crippling attack leaving it vulnerable and adrift. Captain Archer faces a terrible ethical dilemma when they encounter an Illyrian space vessel, ultimately stealing their warp coil to restore the Enterprise's engines. Wrecked with guilt but determined to complete his mission, Archer believes his choice was necessary but visibly bends under the weight of ability. It's a stark, vital episode that asks, 'Do the ends justify the means?'
