The Evolution of Klingons in Star Trek: From 'The Original Series' to Modern Times

The iconic Klingons of Star Trek have undergone significant changes across different series and movies. This evolution includes major plot changes such as the destruction of Praxis and subsequent makeup and casting decisions. This article explores these changes and provides in-depth explanations for the differences in how Klingons have been portrayed.

Key Changes in Klingon History

The evolution of the Klingons can be traced back to several key events. After the events of the original Star Trek series, the Klingons experienced a major disaster. In 2293, the energy plant Praxis exploded, leading to a drastic environmental decline. This disaster left the Klingon Empire unable to sustain its society, prompting them to seek peace with the Federation through negotiations. This marked a significant shift in the Klingons' relationship with the dominant Starfleet.

Another notable change came during a struggle between the Klingons and the Romulans. In 2267, an alliance between the two species broke down, leading to a series of conflicts. The Romulans launched attacks on Klingon outposts, notably the outpost at Khitomer and Narendra III. These events would have profound impacts on the future of both empires.

How the Klingons Looked in 'The Original Series' (TOS)

Initially, the Klingons in the original Star Trek series (TOS) were portrayed with distinctly alien characteristics. They had a bronze-like complexion, sharp pointed eyebrows, and a prominent cranial ridge (forehead bump) that ran from their hairline to just behind their ears. These features were a result of the limitations in special effects and makeup technology of the 1960s. The makeup for Klingons in TOS was quite simple and used only a combination of latex and paint.

Inconsistencies and Conflicts

As Star Trek ventured into the 1980s and 1990s, production values increased, and so did the detail in makeup and special effects. In 1979’s Star Trek's The Motion Picture, the Klingons were redesigned to fit the more advanced makeup and special effects available at that time. This change made them look more sinister and edgy. However, this shift created plot consistency problems for later series and movies.

By the time of the Star Trek: The Next Generation (TNG) series, the Klingons had evolved further. They now had the distinctive head ridges that are a hallmark of their species. This transformation was a significant departure from their TOS depiction and had to be explained within the narrative of the show.

Explanations for the Evolution

Genetic Experimentation and Augments: One of the most well-known explanations for the changing appearance of Klingons is provided by the Star Trek: Enterprise series. This prequel series introduced the idea that in 2154, a group of Klingons experimented with DNA from Dr. Arik Soong’s Augments. The intention was to create a superior version of the Klingons. Instead, this experiment resulted in genetic mutations, including the human-like features observed in the TOS era, such as the loss of the cranial ridges.

Enterprise’s Explanation: According to Enterprise, the augment virus created by the Klingons in their attempt to enhance their genetics led to the transformation of several Klingons. These mutations were contagious and spread over time, eventually becoming a significant part of Klingon society. Some affected Klingons chose to undergo cosmetic surgeries to restore their cranial ridges, further complicating the issue.

Special Effects and Makeup Developments: The evolution in makeup and special effects technology also contributed to the changes in the depiction of the Klingons. By the time of Star Trek: The Motion Picture, there was a noticeable shift in the detail and sophistication of the makeup, making the Klingons appear more advanced and sinister. Although this led to a more visually impressive effect, it also created a conflict with the earlier, simpler depictions.

Casting Decisions and Production Changes

The casting decisions for the Klingons also evolved over time. For instance, in The Original Series, Northern Klingons were primarily used, with Southern Klingons less prominently featured. This changed in later productions, with Southern Klingons becoming more prevalent. Using actors from different ethnic backgrounds allowed for a diverse representation of the Klingon race, which was both practical and artistically beneficial.

Reconciliation Between TOS and TNG: The inconsistencies between the depiction of the Klingons in The Original Series and Star Trek: The Next Generation have been reconciled to some extent in modern retellings. In Star Trek Discovery, for example, certain actors like Jackie Brosnahan (Klingon Commander) and Doug Jones (Klingon Sentries) were used to provide a blend of familiar and new, enhancing the overall continuity of the franchise.

The evolution of the Klingons in Star Trek is a fascinating aspect of the franchise, showcasing how changes in technology, production decisions, and narrative explanations can all influence how a characters are portrayed over time.
