"Our world may be lost but we survive."
a Xindi-Insectoid saying.
The Xindi-Insectoid are a species evolved from a kind of mantis like insect that is aggressive, prone to single minded determination and skeptical of the motives of others.

The early history of the Xindi is a remarkable one but eventually the minor conflicts escalated and they destroyed their own planet in the mid 2030's. Fortunately many of them all ready had colonies off world and they had enough warning that they were able to save much of their population.

The Insectoids were one of the main warring factions and did not accept the fact that their world was going to be destroyed. As a result they did not bother to initiate any evacuation procedures when they were warned by an alien species that their home world was doomed. As a result they lost over 80% of their total population when Xindus was destroyed.

This same species then informed them years later that the humans from Earth would one day destroy all of the Xindi. As a result they built and deployed a probe that they sent to Earth. This probe ended up killing millions of humans. With a successful test completed they started to develop a much bigger weapon that could destroy the planet Earth with one shot.

This alien species was called the Guardians by the Xindi and they practically worshipped them, considering them saviours.

The Insectoids were firmly behind the development and use of both the probe and the much larger version that would be used to destroy the Earth. In fact they argued against Degra when he approached the Xindi council and offered evidence that the mysterious aliens were lying to them and that the humans were not a threat to their very existence.

The Insectoids could not be convinced and they sided with Reptilians. They would not even consider the possibility that the Guardians had been lying to them. When it appeared that the council might vote in favour of stopping the attack they helped Dolim and the Reptilians hijack the weapon and deploy it for use.

A coalition of Primates, Arboreals and Aquatics joined forces with the Earth vessel Enterprise and were able to destroy both the super weapon and the threat of the Guardians who were altering the very nature of space within the expanse.

As a result a kind of peace was achieved between the Xindi and Earth. Over the years this relationship has slowly evolved to the point that the Xindi are currently entertaining the idea of becoming members in the Federation.


Prior to the destruction of their homeworld the Xindi were ruled for eons by the Primates. It was only after they lost their home world that they were able to finally form a joint council with 2 members from each of the 5 species having a voice and a vote. This system worked well until they discovered that the Avians had not been wiped out as believed. It took almost 75 years but finally the Avians were convinced to accept a spot on the council and each species now has 3 representatives.


Xindi-Insectoids are members of the multi-species Xindi race. They are one of the most agressive of the six species, which shared a common genetic ancestry. In appearance, Insectoids have 2 large compound eyes, 2 antenna and mandibles for a mouth. They walk upright on 2 thin legs and have 2 thin arms. Most of the body is covered by a semi rigid carapace and they do not have skin but rather a semi-hard protective coating over their entire body.


The Primates, Arboreals, and Reptilians spoke a common language that was recognized by Starfleet universal translators. The Insectoids and Aquatics understood this language, but appeared to be physically incapable of speaking it.

The Insectoid language is a clicking dialog that is the most unusual and complex of all Xindi, save that of the Aquatics. In fact, there were 67 dialects of the Insectoid language.


The different Xindi species were extremely similar in their functionally-important DNA, sharing over 99.5% despite the apparent physical differences. All the Xindi species shared distinctive ridges on their cheekbones and foreheads.

The Insectoids, like all Xindi species, had distinctive ridges on their cheeks. They were, as their name suggests, insect-like in appearance. Their average life expectancy was estimated to be twelve years. It was easy to find, on their ships, individuals about ten years old, who were probably considered "elders."

They were genderless and reproduced asexually. Also, because of their insectoid nature and the shortness of their life span, they were strongly concerned over the survival of their offspring. They protected their young by making a hatchery brig attached to their ships and shielded it in case of danger, even at the expense of the ship's life support system. Each individual was able to produce large clusters of eggs.

The eggs could not survive out of the ship and were equipped with a gland capable of producing a powerful and subtle neurotoxin. If an unexpected presence was detected in the vicinity of the eggs, the clusters would spray the substance on the intruder, causing (in the latter) an instinctive, obsessive interest in protecting and nurturing the hatchling.


Insectoids interpreted raised voices as a sign of hostility. They were quick to make decisions and were often in alliance with the Reptilians.Both species used to trade their technology between each other and usually agreed on all decisions.


Numerous experts from a wide range of species have been confused by the Xindi religion for many years. The number of unusual contradictions and seeming inconsistencies have left them puzzled and perplexed. First of all is the fact that each species have their own name for their god. Next is the fact that each species perceives that god to be a reflection of their own best qualities. Each species portrays their god as being similar in appearance to them.

What has confused the experts is that all 6 species agree that they all pray to the same god. Furthermore they have never had any hostile disagreements over the many differences between how each species honours their god. They all accept those differences. In fact it is not unusual for Xindi of different species to all use the same temple even if the beliefs, images and ceremonies are nothing like those found in their own temples.


The insectoids call their version of their god Kack’Raach. His image is rarely shown but when it is he appears to be a typical Insectoid with no unusual traits.

The Insectoids do not build temples. Rather they will use any empty space that is large enough to hold all of them. This could be an empty field, mess hall, storage facility, etc.

One of them will be selected at random to stand in the center of the room. This Insectoid acts as a living statue around which the rest will stand, swaying slightly back and forth as they all murmur the 856 rules of observance.


Unlike some of the other Xindi species the Insectoids could not be bothered to save any of their recorded history as well as the ancient writings of their ancestors. What little they still retain was found in ships data storage or compiled from salvaged material.


They have a communal society with rigid rules and hard working citizens going about their business. Their offspring are protected and sacrificing one’s own life for the young of their community is not only acceptable but considered proper.

The Xindi practically worshipped the Guardians, considering them saviors. Children were taught to revere them and give thanks to them at the end of each day. It was a terrible offense to question a Guardian. Crime is almost unheard of unless it is committed by one of the other Xindi species.


Xindi passed down "initiation medals" among the members of a family. Other than this the insectoids do not seem to have any art forms of their own or to appreciate any art forms created by other Xindi or any alien species.


Insectoids have names that grow longer and more difficult to pronounce as they grow older.


They are not the most advanced Xindi species with the majority of their people becoming workers or warriors. They usually get new technology by trading with the other Xindi species. Right now they are slightly behind most Federation member worlds.


The Insectoids are not that concerned with trade and usually only trade with other Xindi for the few raw resources that they can not mine or produce for themselves. They tend to be less inclined to bargain as they do not have the patience or the social skills needed for successful negotiations.


The Xindi-Insectoid ship was a type of warship used by the aggressive Xindi-Insectoids in the 2150s. It consisted of a small central core containing the drive system and three extended wing-like sections extending forward, mounted at 120 degree angles along the fore-aft axis. The ships were heavily armed with pulse-firing particle cannons and torpedoes. They were also highly decentralized in layout, possessing no central control room, reflecting the non-hierarchical nature of Insectoid culture. There was at least one room that had a viewscreen for communications.

In early 2154, Enterprise NX-01 discovered the wreckage of a crashed Insectoid ship while traveling to the Azati Prime system. The Enterprise crew discovered that the adult crew had died when they transferred power from life support to power the on-board hatchery, protecting their young.

Insectoid ships participated in the attack on Enterprise at Azati Prime, as well as the battles to stop the Xindi weapon in February of 2154.

In an alternate timeline in which the weapon was successful in destroying Earth, ships of this type were part of a Xindi assault fleet sent to destroy the last remnants of Humanity in the Ceti Alpha system in 2165.

Federation Intelligence Files

The Xindi (pronounced ZIN-dee) were an alliance of species who evolved on the same planet in the Delphic Expanse, known as Xindus, whose infamous attack on Earth and attempts to terminate Humans in the early 2150s changed the course of history and initiated the series of events that helped establish United Earth as a major interstellar power.

In the mirror universe, Xindi ships fought in a conflict with the Terran Empire sometime prior to 2155. In the 26th century of an alternate timeline, Xindi served on the USS Enterprise-J during the Battle of Procyon V against the Sphere Builders.
