Irken Empire Wiki

"I never liked thermodynamics... Its limitations are so dull, aren't they?”

Born in the vast catacombs of Irk’s robotic smeeteries, Vex is an engineer, physicist, weapons contractor, and former Irken Invader. In the 287 years of his life, he has traveled the galaxy with the military, the Irken Science Program, and, more recently, every so often with a group of scattered compatriots.

As the inventor and contractor for large amounts of technology, Vex is well known throughout the empire, despite his reclusive attitude towards society.

Before Invading[]

Vex as a newborn smeet

Vex began life in precisely the same conditions as every other Irken, born in the vast system of smeeteries under the surface of Irk. After his standard military training courses, Vex was deployed as a foot soldier in an Irken Elite battalion led by the prestigious Commander Thresh. After a relatively uneventful but largely successful campaign on what would become Foodcourtia, Vex was promoted to the rank of Master Sergeant and recommended by Thresh for Irken Elite training on Devastis. Vex passed the Elite test with a high enough score to immediately enter as an Elite Sergeant, and he served for half a century as an Irken Elite before a plasma wound followed by a severe face laceration forced his removal from duty. During the incident, his entire squadron of Elite soldiers was killed in an ambush as well as an entire conjoining squadron. The injury landed him in a medical station, and at this station, Vex made a full recovery save for the characteristic scar over his left eye, which reveals very little about the severity of his initial injuries. Vex never discusses the injury, and rarely talks about his military history whatsoever. He maintained severe psychological wounds from the incident, traumatized by the slaughter of his squadron.

Aboard the medical space station, Vex took a mandatory intelligence test, as is protocol following a head-based trauma. Vex proved to have an incredibly high IQ, so high that an Irken Control Brain made the decision to have him transferred forcibly to a laboratory on the allied Planet Vort to work as a scientist. Vex consented and began his career as a scientist, now bearing the scars of war.

Vex’s research in the scientific community was almost immediately influential. After a failed attempt at a time machine prototype, Vex was able to glimpse and gather a sample of a fourth-dimensional molecular base, referred to by mathematicians as the theoretical particle “Tesseract.” This substance was immediately revolutionary, and with several lengthy patent processes brought Vex fame within the Irken Empire’s research community. With the substance, he was able to create extraordinary technologies with the potential to warp spacetime at will. The use for this substance, Vex figured, was a Tesseract-assisted engine system, which was produced in limited amounts for research and used in a few newer model Armada ships. These early engines improved over time, but were never cost-effective and could not be implemented into very many ships. Due to a lack of effective equipment and a lackluster interest in helping the empire, potentially sprouting from his military career, Vex decided to leave Vort. 

As a result of his legal power over the Tesseract fuel used in some newer Armada ships, Vex had enormous bargaining power, enough to allow him to escape the forced work environment of the Irken Science and Research Program conglomerate and start his own individual company, which had rarely been achieved in the field of Irken scientific work. In the months following Vex’s departure, he was inundated with empty deactivation threats and bad business, and was unable to hire any workers due to his company’s autonomy. 

Vex was able to purchase a scrapped space station and refurbish it using funds from his military career, but languished alone in the station for years, unable to find a contract with anyone and barely surviving by selling Tesseract fuel to the few ships that used it. During Operation Impending Doom Two, the Irken Science and Research center on Vort, responsible for massive weapon production, was destroyed, and the Empire reluctantly signed a contract with Vex for weapons manufacturing. Vex was finally able to purchase proper production supplies and hire the first workers, among whom were Plixx and Graf. The newly legitimized Vex Laboratories was able to push through old weapon designs as well as produce new ones, the vast amount of which were powered by the Tesseract fuel that birthed Vex’s scientific career. With advances in Tesseract technologies, these weapons rely on this fuel to create incredibly deadly projectiles capable of disintegrating nearly any substance.

Despite Vex’s scientific achievement and relatively high autonomy from the Empire, he remained highly reclusive and still struggled with psychological challenges from his military days. Upon meeting a discombobulate band of Irken vigilantes and touring the galaxy and fighting strange and obscure threats with force and with knowledge, Vex recovered significantly from his previous mental state, although he maintains a stoic and nonchalant façade to hide his emotional stress.

Vex is largely consumed by his work. Given its dangerous nature, he is often seen as extremely rude for his tendency to ignore everyone while he’s working, even his friends and high ranking officials. Vex generally treats people with respect, but he maintains a reclusive, stoic personality despite his internal emotions. Only when Vex has maintained a truthful relationship with someone for a very long time will he open up and adopt a more friendly demeanor. Vex is terrified of responsibility for the deaths and injuries of those around him, and often places himself in considerable danger while ordering others to keep at a safe distance. He nonchalantly brushes off such incidents in fear that he will relapse into the traumatic state resulting from his squadron’s slaughter. 

Vex and Vax in "The Growing Darkness"

During Vex’s long confinement alone in his space station following his escape from forced labor on Vort, he relapsed into an unhealthy mental condition. His recent contact with the likes of Jib, Schmoob, Menami, and Mario, among others, has helped him regain a sense of confidence in his actions.

Relationships --- WIP, info may be conflicting past this point ---[]

  • VIR- As Vex's SIR unit, VIR is a loyal ally and one of Vex's greatest tools both in battle and in the laboratory.
  • Invader Vax- Vex and Vax are friends, and Vex often contacts him when in need of assistance. They have worked together quite often, but Vex has noticed that Vax has gained an obsession with the paranormal, and keeps a watchful eye on Vax, fearing that he might one day become like Knox, Vex's and Vax's predecessor.
  • Invader Plazatrax- Vex sees Plazatrax as a helpful ally, with his databanks always filled with information useful to Vex's various projects. They are friends.
  • Nightmare Vex- Vex sees his Nightmare counterpart as either a great ally or a dangerous enemy, depending on the situation at hand. As his exact mental and physical equal, Vex is not intimidated by him.
  • Invader Zim- Vex is amused by Zim's various blunders, but despises him for destroying his lab on Vort when Zim created an Infinite Energy Absorbing Blob during his training. Vex is often surprised by Zim's apparent inability to stay hidden. During Vex's mission to Earth, he had to brainwash an entire theatre that Zim crashed into in a giant metal pig.
  • Invader Mez- Vex and Mez have quite a bit in common. As Mez once pointed out, "Great minds think alike!" They assist each other with many different experiments and missions and are good friends.
  • Invader Jib- Vex is good friends with Jib. Vex often helps Jib update and refine his equipment. Vex helped design Jib's mechanical eye and arm.
  • Invader Zyl- Vex knows Zyl only as a customer, but now knows that he is Jib's mortal enemy. This fact leads Vex to like him less.
  • Invader Xav- Vex and Xav share interests in the scientific world, and are good friends. Vex, Xav, and Vax often meet at the nearest good Irken Coffee house to discuss their scientific discoveries.
  • Commander Thresh- Vex and Thresh are good friends. They have worked together on many missions, but first met of Vort, where Thresh was assigned to investigate and destroy a large blob creature that killed Almighty Tallest Miyuki.
  • Invader Ark- Vex has a sibling-like relationship with Ark, and during his mentoring of Ark as an engineer on Vort, he nicknamed her "little sister."
  • Plixx- Vex and his Technician Plixx have worked together for years, and are good friends, seeing as they both enjoy the fascinating world of science. Vex is Plixx's boss, but Plixx is more like an apprentice to Vex.
  • Irken Elite Crux- Vex supplies Crux with weapons and equipment, and admires his mental and physical prowess. Crux reminds Vex of his younger self. They are friends.
  • Graf- Vex is Graf's employer, and is grateful of Graf's prolonged service with him.
  • Vira- Vex is strongly opposed to Vira's operations against Irken troops and citizens, knowing that she has killed almost a hundred of her own species.
  • Hakk- Hakk and Vex are enemies. They have tried to kill each other on a number of occasions, but they are fairly evenly matched. Vex is currently unaware of Hakk's operations.
  • Schmoob- Vex thinks that Schmoob is quite eccentric, but they are friends nevertheless. Vex does not know about Schmoob's mission to Robloxia, however, so doesn't judge him on any events that may have happened there.
  • LIR- Vex thinks LIR is actually quite annoying, but will tolerate him because of his fighting abilities and help while on missions.

Facts of Doom[]

Vex Infiltrating the Resisty!

Vex working on his ship's ion converter.

Vex despises the publicized nature of Operation Impending Doom Two, believing that compromising information is much more likely to leak.

Because of his importance, the Tallest granted him permission to install a bioelectricity manipulator into VIR.

Vex occasionally formulates plans to overthrow the tyrannical control brains and regain real Irken leadership for the Empire.

Despite Vex not being all that much older than Zim, he must disguise himself as an adult Human on Earth, and a non-Vortian refugee when in the Vortian system.

Vex invented advancements in transmission equipment that allows any interstellar transmissions to travel past the speed of light, allowing for long distance calls throughout the galaxy while traveling near the speed of light. This technology resides inside all modern pieces of Irken equipment, including The Massive and all main control brains.

Vex owns a PAK-less clone of himself for an organ donor if he is ever severely injured. The clone is hooked up to a life support system to keep it alive.

Vex owns a battle cruiser called the Plague Runner and is a licensed fleet commander. He has a crew of highly trained pilots and gunners aboard the ship with him at all times.

Vex's synthesized skin disguise makes him impervious to dangerous Earthly substances like heavy-ion water and meat.

As one of the main military equipment providers for the Irken Empire, Vex either has invented or can easily get his hands on equipment and weapons needed for each mission he completes.
