A mysterious race of ancient and extremely powerful insect-like machines, the Drakk are found near the end of Unreal II. The Drakk homeworld lies in an uncharted sector of space, where every human expedition team was met with unknown fate. The Drakk are highly advanced and uses plasma and laser weapons, and can rapidly repair themselves. They also have the technology to preserve and animate parts of biological beings, which enables them to engage in cruel biological experiments on captured members of the other species, in an attempt to create the perfect soldier. Such experiments can be found in their homeworld, where Skaarjs and Humans are being melted and kept in jails. The Drakk seems to be the guardian of the artifact of Unreal II, awakening when the protagonist tries to escape with one part of it; another part of the artifact is stored in the heavily defended center of the Drakk homeworld.
Gen Mo' Kai
The Gen Mo' Kai are a humanoid, gecko-like species, with digitigrade feet and short tails. Hailing from a planet named Arborea, the lizard-like Gen Mo' Kai are a renowned species of honourable warrior males and hunter/scavenger females (they only have two sexes). Their society is clan(family)-based rather than individual-based, and either males or females may become clan-leaders. Combat prowess his highly prized amongst this predatory species, though they are also intelligent and highly inquisitive. Most Gen Mo' Kai who enter into the human empire's tournament bloodsports do so willingly, for the challenge and the sport of competitive combat. Their society is highly traditional and ceremonial, and some Gen Mo' Kai choose to wear familial death masks to war, bearing countenances which are highly stylized and often disfigured or gruesome looking.
The Izarians had a small empire of their own and enslaved many minor races before they ran into the Skaarj and became slaves themselves. Due to their sado masochistic tendencies, it is debatable as to if they actually mind at all if they are slaves or not.
The Izarians resemble large monkey-like insects, and the Xenomorphs. They are about 5 feet tall, have four arms, two legs, an elongated head with sharp teeth, blue blood, blue skin and areas of their skin that glow a lighter shade of blue.
Their social structure is much like that of an ant or bee hive. They cannot think independently, but their Skaarj masters allow them to hunt in packs against the Terran forces that the Skaarj are at war with. The Izarians, as well as serving the Skaarj as slaves, are also used by the Skaarj in combat as light warriors. They usually hunt in packs of seven or eight with one Skaarj commander, as Skaarj are much stronger, faster and more intelligent than Izarians. The Izarians use weapons called EMP Staffs or Electric Spears. The Skaarj attach crystal EMP restrainers on their slave's Spears so as not to give them anything too powerful.
A veteran clan of reptilian alien warriors, slaves to the Skaarj during the time period of Unreal. The Kralls are biped creatures, and are possibly more intelligent than the Izarians. In Unreal Tournament 3, they serve as soldiers for the Necris army. There was much initial confusion when media of the Krall was first released; many players thought they were in fact Skaarj, because they resembled Skaarj more so than the Krall. It was later confirmed by Epic that the aliens were in fact Krall, and not Skaarj. They are usually equipped with spears that can fire plasma like the protagonist's Dispersion pistol. In the original Unreal, Kralls are often seen patrolling fortified positions like a captured Nali Castle.
It is not known how the Kralls have come to become the slaves of the Skaarj. However, the master-and-slave relation between the Skaarj and the Kralls is a problematic one. If a Krall hit a Skaarj with friendly fire, the two will begin to fight each other instead of the player.
The Krall has only appeared in the original Unreal. Hence not much background information is known about the Kralls.
The Nali are a primitive race, whose home planet of Na Pali was invaded by the Skaarj. They are humanoid creatures, but have four arms. No living female Nali has ever been seen, but female Nali statues can be found on Na Pali. The statues hint that female Nali are similar to male Nali in terms of facial features and body shape, but have four breasts (to pair with the arms). In the temple of their lightning goddess "Vandora", there is a mural of the Nali female deity which looks like a woman, but has four arms and four breasts. The Nali are not technologically advanced; they are wholly unaware of such things as weapons or power-ups. For this reason they store such objects in their urns, crates or barrels, not knowing what to do with them. Most of them live in small, simple houses, although there exist a few castles; Nali buildings are reminiscent of Medieval architecture. In keeping with their backward technology, their main occupation is farming, as seen by the fact that they build sheds for Nali Cows. Many of them are fond of keeping diaries, often describing the arrival of Skaarj on their planet, believing them to be "demons who came from the sky". They have a highly spiritual culture, visiting their ancestral shrines and building many churches. They also have extraordinary abilities that could be described as supernatural; several Nali can be seen levitating, turning translucent, and vanishing altogether. There are also some Nali ghosts who apparently visit and honor the tombs of their ancestors (as seen in the level "Bluff Eversmoking"). The Nali caste of the priests use tattoos to ornate their bodies, using colours such as red and blue.
Nali and Nali 'War Cow' models were released in an official free update for the original Unreal Tournament, allowing players to (humorously) take these pacifistic creatures into battle. An audio taunt available to players in Unreal Tournament 2003 series is "You fight like a Nali!".
The Skaarj (pronounced "scaar") are an advanced race of aggressive extraterrestrial beings generally living in a highly tribal society, originally introduced in Unreal, but subsequently found in all later games of the series, usually as the antagonists. The Skaarj design seems to have been influenced by alien designs from various other franchises, often having green/yellow/blue skin, tusks of varying lengths, and are generally reptilian in appearance. Although they appear reptilian, they are in fact related by design to insects. Because of their appearance, many of the logs left by deceased crew members in the original Unreal refer to them as "lizard men". Some, but not all, Skaarj are augmented with cybernetic implants.
At the head of any given Skaarj clan is a Queen, similar to the Xenomorph Queen, who lays eggs in which eventually a bug-like creature (a pupa) emerges. These pupae eventually grow into the Skaarj as they are commonly seen. No female Skaarj besides the queen are found in the original Unreal, but no female Nali are found either (except for the mural of goddess Vandora). This may be due to restraints in model counts, lack of Skaarj sex diversity, or what is commonly acceptable in games at the time of release. A female Nali may have been supposed to be included in Unreal Championship 2 as shown by concept art, but wasn't included.
A Skaarj warrior's main weapon is called a Razik, and consists of two (sometimes surgically attached) wrist mounted blades on each hand, similar to a weapon used by the Predators from the Predator franchise. This blade design gave birth to the design of the different variations of the Circle-U logo of the series, and the Skaarj themselves can be considered the series' mascots. The Razik also is able to fire electrically charged shots of energy, which form between the blades, and fire in pairs. Skaarj troopers do without Raziks and rely on projectile based weapons such as the Razorjack. The Skaarj Razik design is also used in the different Unreal game logos.
The Skaarj are highly intelligent, fast, strong, and their clans usually remain solitary, perhaps due to conflicts in code or competition. The clans have shown a significant amount of cooperation in the human/Skaarj wars, however. Most Skaarj consider all other races to be inferior, and that it is the destiny of the Skaarj race to rule over all others. Many races such as the Nali, Krall, and Izarians have been enslaved by the Skaarj, who are technologically superior.
As well as the separate clans, the Skaarj Empire was formed with the goal of ruling the universe. After enslaving and destroying a large number of alien species the power hungry Empire moved onto humans. First contact with this Empire came when the New Earth Government attempted to recover the crashed prison vessel, the Vortex Rikers. Over a full year the humans and the Skaarj Empire fought a large number of battles, at areas such as Avalon and eventually Earth itself. This began the "Seven Day Siege" in which the Skaarj fleet surrounded the Earth and attacked. Several million of the Earth's population were killed and the NEG struggled to hold the invaders off. Eventually, on the final day, the NEG Commandos assaulted the Skaarj Mothership and destroyed it from the inside. The Skaarj were sent into full retreat and the human race lived to see another day.
Since the human-Skaarj war, the Liandri Corporation experimented with Skaarj/human hybrids in their Grand Tournament (or the Unreal Tournament). In the latest Tournament, actual Skaarj from the deadly Iron Skull Clan have participated, generally holding that they will indeed one day conquer humanity, and the Tournament gives them the opportunity to kill humans in vast numbers (albeit in vain, since Tournament contestants are immediately resurrected upon death) until that day arrives. The Black Fist clan opposes the Iron Skull clan, who are their sworn enemies, and members of Black Fist, Mekkor and Skrilax, are currently enrolled in the Tournament, hoping to battle the Iron Skull. A few Iron Skull members have been in the series since the beginning, even in Unreal 1, such as Dominator and Guardian, and are also fighting in the latest tournament.
White-skinned, gothic-looking undead with advanced technology. They also appeared in UT, and in UT2004 with the UT2004 Mega Pack. In Unreal Championship 2, they are described as humans resurrected via the "Necris Process" They are the antagonists of Unreal Tournament 3.
Egyptians, who have been living on another planet and have advanced technology.
Humans, who have been gene-boosted, giving them added qualities such as increased strength and aggressiveness. They mostly consist of disgruntled prisoners and criminals.
The Corrupt (Liandri)
A team of cybernetic robots with very advanced programming. Their leader is the first champion of the Tournament, Xan Kriegor. The robots have been created and are financed by the Liandri Corporation itself. They are upgraded each Tournament.
A group of hardened mercenaries, led by Brock and his girlfriend Lauren (who will stay a part of this team). The Iron Guard feature in UT,UT2003,UT2004 AND UT3.
Lead by Malcom, this famous team of former NEG soldiers needs no introduction.
Not much is known about this team at this point. One of the characters of this team can be seen in a publicity screenshot - he is a black man wearing red armor.
