Humans
"You want diversification, look around. Humans are everywhere and we're all different. Each of us has our own strengths and weaknesses, our own codes and life values, our own hopes and desires. That's what makes us strong and that's why we'll outlast the other races in Slayer's picture."

The predominant race in the World of Progress is the Humans. They at first glance appear to be the 'runts of the litter', being weaker than Shaktar, slower than Wraith Raiders and without the advantageous of ebb manipulation that the Ebons have. However, on a closer look the Human's primary advantage is their adaptability to any situation. Humans are a resilient race who will cling to any vestige of life that they can. If their surroundings do not provide them with something they require, they will either move on or create a tool to serve that purpose. In the World of Progress, the Human's main strength is their unceasing creativity in topics as diverse as media investigation to creating artificial life. Being so adaptable, there are very few planets that have not been colonised by Humans within the Known Universe. Although a stereotypical Human tends to be quite self-centered and concerned only with events that affect them directly, each generation tends to produce specific individuals that are aware of their bigger role in the Known Universe and will help the whole race advance. In the structure of SLA Industries it is often these Humans that have risen to prestige positions, whether that be in charge of a Department or as a popular media personality. This is in sharp contrast to the majority of Humans who in the World of Progress are unemployed and reliant on SLA Industries for all their needs.

Frothers
"You only get one life so you have to make the most of it from day one. There's no point planning for the future when DarkNight can end it all with a big bomb when your sleeping. Live for the moment, that's all that counts."

It is only in the last few centuries that Frothers have been recognised as a separate race within the World of Progress. Originally Humans, Frothers have evolved to become a more combat orientated sub-species of Humans. This mutation has occurred due to the proliferation of legal and non-legal drugs in their culture. These drugs, mainly provided to them by SLA Industries, have made them stronger whilst only slightly affecting their cognitive abilities. As an Operative, Frothers have access to the more destructive drugs that SLA Industries make and can appear to be indestructible in the middle of combat. The media tends to love the image of Frothers battling it out with subversive terrorists, whilst in their clan tartans and their flying dreadlocks. The downside to their life is that the drugs have a terrible toll - the average life-span of an Operative Frother is only two years.

Ebon
Similar in appearance to Humans, but with eyes without irises, the Ebons are often referred to as Intruder's children. The Ebons main strength comes from their manipulation of the Ebb, a force that is apparent in everything in the universe. It was Intruder who taught them how to use their ebb-abilities. He also taught them to express their emotions in everything that they do. Operative Ebons are often characterised by their haunting DeathSuits, Science Friction constructs that are used to focus and channel the Ebb forces for manipulation. These suits become more than just armour to the Ebons and many become distraught if they ever lose it. The Ebons are often the most feared of the races as their powers can cause devastation, either through direct force or through more subtle mental manipulation.

Brain Wasters
The Brain Wasters relationship with the Ebons is similar to that between the Frothers and the Humans. Whereas the Ebons tend to be creative and artistic with their ebb abilities, the Brain Wasters tend to be more brutal and aggressive. The Brain Wasters come from a genetic defect in Ebons, that causes about 1 in 10 Ebons to be born with the characteristic scorching around their eyes that is the first sign of being a Brain Waster. Socialising more with their own kind, Brain Wasters are known as crude, moody and paranoid. They are also some of the most creative individuals in expressing their hatred and anger in forms of violent acts that shock many. They are one of the true inhabitants of the World of Progress, knowing that the surrounding universe is falling into nihilism and not really caring. SLA Industries actively searches for Brain Wasters to become Operatives, knowing that even though they are hard to train, their manipulation of the Ebb makes them irreplaceable.

Shaktar
The mysterious red-coloured aliens known as the Shaktar were saved from destruction in the Conflict Wars by Intruder. Taller than the tallest Human, the Shaktar are a proud people who honour their pact of survival with SLA Industries by offering their best soldiers into service. The Shaktar are true aliens in the World of Progress; their ideals and language are hard to adapt to the live of the Operative and the narcissistic society around them. They tend to train more in the ways of combat then the other races, being better able to protect those around them. Even the weakest Shaktar is a fearful sight in combat; especially if fighting for a cause, or to help those in his care.

Wraith Raiders (Wraiths, Wraithen)
Born in the hostile arctic environment of Polo, the life of a Wraith Raider is a fight for survival from day one. The Wraith Raiders were saved from extinction by Senti and they have become one of the most feared hunters in the World of Progress. Compared to pre-conflict war tigers and bears, the Wraiths prefer a solitary life, predominantly taking BPNs which require them to hunt down targets, rather than more cerebral or mundane BPNs. The majority of Wraiths train under the Scout Package at Meny, however, there is an increasing number who are starting to train under Kick Murder Squad training. Originally preferring to kill targets from long range, there is a growing interest in getting as close to their victims as possible. SLA Industries is also forcing some of the newer Wraiths to join with mixed race squads, so that they can learn to work well with others, complementing the groups skills.

Karma Bio-Genetics
"We are the best troops in the World of Progress, faster, stronger and fitter than anyone else. Slayer wanted us to help him win and we haven't let him down. We try to make Taarnish proud and live up to everything that Intruder wants us to be. Created by SLA Industries, we will happily die for them as well."

Although not technically a race, the bio-genetic races created by Karma are definitely numerous enough to count as one. Based off the initial gene-code of Intruder, the most common Stormers are the 313 Malice Stormers. These hulking brutes combine fast reactions and high strength with an impressive bio-regeneration, making them the best soldiers in the World of Progress. It was the introduction of the 313 that helped SLA Industries to succeed as overall survivor of the Conflict Wars. The 313s were hired out to all who could afford them as front line troops. Then when Mr. Slayer wanted to end the Conflict War the Stormers all turned on those they fought for, killing as many as they could before they themselves died. Nowadays it is not a rare site to see a Stormer as part of an Operative Squad; they do not always have the level of concentration for some BPNs, but they can provide violent support if the Investigation leads to conflict. In recent years the gene-code of Intruder has been modified to allow for three new types of Stormers; the 711 Xeno, the 714 Chagrin and the Vevaphon. The Xeno has the added ability of a camouflaged skin and an armoured body. It also has seven eyes, which allow it a larger field of vision. The Chagrin has higher potential strength than a normal 313 and is often recognised by its vicious looking tusks. It is one of the few things in the World of Progress that makes even a Shaktar look small and weak. The Vevaphon is a polymorphic bio-genetic which has the ability to change its appearance and structure at will. This fluidic gene-code allows it to change it to 'grow' additional limbs, armour and weapons. Recent developments in the understanding of Intruder's gene-code have also allowed for several upgrades to the basic Stormer variants; from enhanced claws and strength to additional limbs and tails.

Necanthropes
Necanthropes are seen as the next step in Ebon evolution. Large demonic creatures, Necanthropes are created from Ebons who have reached a high level of understanding of the Ebb. As the Ebon becomes more powerful their every waking moment starts to be haunted by the 'Dream Demons' and the Watchers of the Necanthropes. Finally, when the Ebon has made the decision to travel beyond his current existence, he is guided towards the White, from whence he will return as a Necanthrope or won't return at all. Necanthropes are the most feared beings in the World of Progress due to their appearance and their apparent disregard for most living creatures. To see a Necanthrope is an unforgettable sight, but to be on the receiving end of their anger is a situation that most will be unable to survive.
