Biology Klingons possess a robust and enduring biology as well as large and muscular statures. Klingons have been seen on multiple occasions possessing physical strength equal to or superior to that of
Jem'Hadar and
Hirogen, two other races possessing immense strength, and the half-human
B'Elanna Torres proves more than a match for a
Vulcan. Their anatomy is redundant and supernumerary; every organ has a backup, including an extra set of kidneys, an eight-chambered heart, a third lung, a secondary brain stem, as well as an extensive and hardy skeletal structure. This redundancy is evident even at the cellular level; for example, the Klingons have backup synaptic networks in their nervous systems, allowing them to grow a new spine, as was demonstrated with Worf when his spine was surgically removed and replaced with a transplanted, genetically cloned new one. Their rapid metabolism allows injured Klingons to heal quickly. All of this makes Klingons extremely hardy and difficult to kill, as necessitated by their aggressive nature, and resistant to physical trauma, environmental exposure, and illness. Klingons alone have a natural resistance to "
the Phage," which plagues the Vidiians of the Delta Quadrant. Like
Cardassians, they avoid cold temperatures. Klingons also have a heightened sense of smell as suggested in "Birthright, Part II" in
The Next Generation, when Worf and a Klingon boy go hunting and can track an animal by scent. Klingon children are fierce and aggressive by nature; from as soon as they can walk, they are instructed into honing their hunting and combat skills, strengthening their physical prowess and agility. Like humans, they go through a form of puberty, which, as Picard puts it in
Star Trek: Insurrection "hardly does it justice" and includes sudden bursts of hair growth, extreme mood swings, violent tendencies, and the Klingon equivalent of acne (called 'Gorch' in Klingon).
Culture In comparison to
The Original Series, Klingon culture is thoroughly examined in later series' episodes, part of a larger movement by
Star Trek writers to deepen viewer understanding of the alien races of the franchise. The Klingons adhere to a strict code of honor, similar to feudal Mongolian or Japanese customs; however, some, such as Gowron, appear to struggle to live up to their ideals. Their society is based on war and combat; ritual suicide is often preferred over living life as a crippled warrior, and may allow a warrior to die with honor. To be captured rather than killed in battle brings dishonor to not only the captive but his descendants. Death is depicted as a time for celebration, not grief. The Klingons' spiritual leader is
Kahless, a messianic historical figure who established early codes of honor and was the first Klingon emperor. His fabled weapon, the Sword of Kahless, is depicted as a unique
batleth that serves as the Klingon equivalent of the
Holy Grail. In the
TNG episode "
Rightful Heir", Kahless appears in the flesh to Worf, who had doubted his Klingon faith. This Kahless is revealed to be a clone, created in an attempt to bring Klingons together, and who is chosen to lead the Klingon people as a figurehead.
Language is the author of several books about the Klingon language, which he developed. The Klingons have their own language that was developed for the feature films, often described as "guttural". For
The Motion Picture,
James Doohan, the actor who portrayed
Montgomery Scott, devised the initial Klingon-language dialogue heard in the film. For
The Search for Spock,
Marc Okrand, who created the Vulcan dialogue used in the previous film, developed an actual working Klingon language based on Doohan's original made-up words. Okrand was presented with a difficult task of contriving a language that sounded alien, while still simple enough for the actors to pronounce. Okrand reasoned the language would be indicative of the culture - the Klingons' language focuses on actions and verbs, like Mongolian. Adjectives do not strictly exist; there is no word for "greedy", but there is a verb,
qur, which means "to be greedy". The language does not contain the verb "to be", which meant Okrand had to create a workaround when director
Nicholas Meyer wanted his Klingons to quote Shakespeare and the famous line "
to be, or not to be" in
The Undiscovered Country. After its initial creation, Okrand has frequently created new words, so that the total number of words has grown up to approximately 3,000. Okrand persuaded
Pocket Books to publish
The Klingon Dictionary in 1985; in it, Okrand elaborated on the Klingon language's grammar, syntax, and vocabulary. While Okrand expected the book to only sell as a novelty item, eleven years after publication it had sold 250,000 copies. Other Klingon groups run blood drives, bowling teams, and a golf championship. The Klingon language's prevalence is not limited to books; a three-disc video game,
Star Trek: Klingon, requires players to learn the language to advance. In May 2009, a joint collaboration between the KLI, Simon & Schuster, and
Ultralingua launched the
Klingon Language Suite for the
iPhone concurrent with the release of the new movie. The popularity of the language meant that in 1996 it was considered the fastest-growing constructed language, ahead of other languages such as
Tolkien's Elvish or
Esperanto. In 2018, the language learning app
Duolingo added a Klingon language course, which is as of June 2022 in Beta. While the language is widespread, mastery of the language is extremely uncommon. Okrand himself is not fluent, and the actors who speak the language in the
Star Trek series are more concerned with its expression than the actual grammar. Klingon is one of many language interfaces in the
Google search engine, and a Klingon character was included in the
Wikipedia logo before its May 2010 update, when it was replaced by a
Geʿez character.
Starships As the Klingons are portrayed as a warrior culture, Klingon starships are usually depicted as
warships, heavily armed with a variety of
particle beam weaponry and
antimatter warheads. Many Klingon ships also make use of
cloaking technology to hide the vessel from view. The first Klingon ship design used in
The Original Series, the D7-class battlecruiser, was designed by
Matt Jefferies to evoke a predator's shape akin to that of a
manta ray, providing a threatening and instantly recognizable form for viewers. The configuration of Jefferies' design featured a bulbous forward hull connected by a long boom to a wing-like main hull with the
engine nacelles mounted on each wingtip. Later Klingon starships by other designers kept to this same overall configuration, although updated to reflect their respective time periods:
Rick Sternbach's designs for
The Next Generation and
Deep Space Nine drew on elements of Starfleet ships features to reflect the alliance between the Federation and the Klingons, while
John Eaves' designs for
Enterprise incorporated more rugged and primitive construction to make the vessels appear consistent with the earlier time period.
Homeworld The Klingon homeworld has been given several names; according to Marc Okrand, the planet would have been referred to in several ways, just as Earth is referred to variously as "the world" or "Terra". Early
Star Trek literature referred to the planet as Klinzhai, but
The Next Generation episode "Heart of Glory" called the planet Kling. The film
Star Trek VI: The Undiscovered Country established the name as Kronos; Okrand later devised the Klingon transliteration "Qo'noS". In
Star Trek Into Darkness, the planet's name is both spelled and spoken by Starfleet personnel as Kronos. According to the non-canon "Klingon for the Galactic Traveler", Qo'noS (said to be in the
Omega Leonis star system) is depicted as green when viewed from space. It includes a lone, huge
land mass with a vast
ocean, a severely tilted axis that causes wild seasonal changes, a turbulent
atmosphere and extremes of both warm and frigid weather. The planet is also home to the Capital City of the Klingon Empire, which features prominently in several episodes of
The Next Generation and
Deep Space Nine. In
Star Trek Into Darkness, one province of Qo'noS is depicted as an unpopulated and abandoned post-industrial sprawl. A moon,
Praxis, about 1/4 of the diameter of Qo'noS is seen in orbit. Its destruction was a plot point in the film
The Undiscovered Country, the after-effects driving the plot of the film and later events in the
television series
Star Trek: The Next Generation. In
Star Trek: Starfleet Academy, Qo'noS is revealed to have been destroyed in the Burn along with several other worlds, leaving the Klingons an endangered species. In "Vox in Excelso," the Klingons settle on a new homeworld in Federation space, Faan Alpha, which is stated to have virtually identical conditions to Qo'noS. ==See also==
