There are countless types of aliens UFO witnesses have claimed to have seen over the years. However, the overwhelming majority of them fall into roughly six categories. These classifications are listed below along with what information we have about them. This list should in no way be considered complete and is intended as a guide only to help witnesses relate their stories.
The Grays (or Greys)
Without a doubt the most famous of all aliens, the Grays are featured as the aliens of choice in Steven Speilberg's Close Encounters, the X-files and numerous other TV shows, books and movies. The Grays represent almost 80% of all aliens allegedly encountered by witnesses in the last 40 years or so.
Overall descriptions vary somewhat on a case-by-case basis, but the average Gray alien can usually be described as between three and five feet tall with a fragile, thin body and oversized head possessed of no hair. Faces have large black eyes, small nose and mouth and no identifiable ears. Appearance can best be described as almost fetus-like, and reports indicate the Gray aliens have at least four elongated fingers, with some witnesses claiming to have seen as many as six digits per hand. Witnesses also claim aliens of this type often have either webbed hands, webbed skin or both. Skin color tends toward varying shades of gray (hence the name) and reports have these beings wearing either skin-tight suits of the same color or no discernible clothing at all.
Grays are most frequently the aliens reported in abduction cases and seem to be the only aliens involved in mass abductions. The purpose of such abductions is almost always reported to be experimentation for breeding purposes, in which sperm and eggs are taken by force from abductees for use in creating a hybrid race of human and gray. Other reports of advanced surgery for other purposes have been recorded, but the end purpose of these experiments remain unclear. Often victims of both types of experimentation claim to have been implanted with small metal or silicon devices. Speculation is that these implants are tracking devices, and given the fact that abductees often claim to be abducted from early childhood throughout their entire lives, this may have some weight. It is also believed that Gray aliens are responsible for cattle mutilations the world over.
The Grays do not seem to be overly cruel to humans. Most witnesses report their treatment as impartial, something akin to the relationship between an animal and veterinarian is a comparison that has been drawn by many abductees. It is during these experiments the Grays exhibit a powerful form of psychic power, actually able to communicate not only thoughts but emotions as well. It is also related by many witnesses that these aliens use a form of mind control power force them to stop resisting the abduction process.
While the experiments are very demeaning to the victims, the Grays appear to do no lasting bodily harm and tend to just drop abductees off near or exactly where they found them. Recent reports have also linked these types of UFO abductions with ovarian and genital cancer, as many alleged victims, many with no family history of cancer, have come down with the disease within a few years of their alleged abductions.
Reports from witnesses sometimes reveal more detail about grey social structure and society than all the other types of aliens reported. The most common of these is the different types, or sub-types of greys who vary in size (mostly height) and mental powers. Many accounts also incorporate the nordic aliens into the grey society. We will be planning a separate and more detailed account of this grey society in updates to the UFO Reporter.
The Nordics/Blondes
Reported mostly in the 1950s and 60s but declining steadily in reports after that, the Nordics get their name from their appearance. They tend to look like blond haired, blue-eyed, light-skinned men and women in excellent physical condition who wear clothing similar to that of humans. Their nature has often been called "catlike" because they move with great agility and seem to have superior strength and dexterity. Usually six to seven feet tall, they tend to be very imposing and many reports show them to have certain psychic powers. The most common of these seems to be a form of telepathic suggestion, wherein the witnesses actually have a conversation with the Nordic but don't seem to remember the alien actually "saying" anything.
The overall behavior of the Nordic aliens tends to be almost informal. Most encounters with these beings tend to take place in rural towns or on highways in areas with low populations. Their conversations with humans tend to be deceptive and with no real point, yet those contacted by them don't seem to realize this until long after the contact has taken place. Few cases of Nordic contact seem to involve abductions or experimentations.
Reptile
The Reptile alien is by far the most violent of all the alien races reported over the world. Reptilian aliens stand up to eight feet tall in a roughly human shape and have scaly green skin with yellow to green snake-like eyes. Their strength tends to be superior to that of humans, and most alleged abductees found themselves hopelessly outclassed physically by these beings. In some cases, their eyes tend to be overly large like the gray aliens, leading some to speculate they are in fact Grays the witnesses can't quite remember clearly. In any case, the reptile aliens act much differently than their Gray counterparts. Their hands tend to be taloned, but fully capable of manipulating tools and weapons.
The Reptile aliens, by most accounts, are encountered in pairs or threes, usually at night in a field or forest. Reports have these aliens firing beam weapons on humans, killing or immobilizing them, and taking them to their ships for experimentation and in some instances torture. Documented accounts (including one we picked up not long ago) are very gruesome indeed, involving disemboweling or dismembering of humans or animals. Few reports involving the Reptiles are pleasant to hear.
Robotic
Few reports have surfaced about these aliens, and those that do sometimes place them in the service of other alien types, usually the Grays. These aliens tend to be of artificial construction, usually some kind of shiny metal, with various appendages for specified tasks, which usually seems to include collecting samples of everything from soil, plants, and in a few cases humans.
Some witnesses have described the robots as hovering disks up to seven feet in diameter or cylindrical creations in the more conventional perception of a robot, complete with blinking lights and dome-like heads, and yet others give them a more human description. Many reports place them as scouts for the Grays, and at least one report had a number of them controlled by a Nordic. Usually, they are encountered singly, roaming forests and even reported sifting through garbage in remote trash dumps. Based on the majority of reports of encounters with these mechanical aliens, their purpose seems to be more for scrounging and scouting than for direct contact with humans. Most cases involving robots usually have the robots leaving the area when coming into contact with humans. Whether the mode of travel is hovering, walking or rolling on wheels, the robots seem to exit the area with remarkable speed.
Dwarf/Goblin
The Dwarf/Goblin is a class of aliens that seem to resemble the class of mythological creatures that they are named after. Like the mythological beasts, they tend more towards practical jokes, pranks and other annoying tricks than in the actions of the other alien classifications.
The Chupacabra beast is considered by many ufologists to be an extension of this alien classification. Whatever its origins farmers, police and even government authorities have taken the creature's killing of goats and other animals very seriously, to the point of sending out armed patrols to hunt the creature down.
It is arguable that this class is actually an extraterrestrial at all. Indeed most cases involving these creatures do not follow the same patterns of most human contact with aliens. They seem to have no purpose other than to accost humans and have fun at their expense. To date, they have not been associated with experiments, abductions in the extraterrestrial sense (though in the sense of the traditional fairy tale this has occurred) or alien spacecraft of any kind. They are, however, included because they are still a subject of paranormal encounters and their relationship with other extraterrestrials is still a remote possibility.
Apparition/Hologram
This type of alien appears as an insubstantial entity, existing in sight and sound only but devoid of any physical mass. The Apparition has been reported to walk through walls and is often hard to look directly at, as such entities are usually surrounded by shimmering or bright lights which obscure much of its features. It is speculated by many ufologists this is a safe form of investigation for alien beings, who can use some kind of hologram or projection technology to investigate terrestrial targets without actually being near them. No cases to our knowledge involving these types of aliens have included abductions or anything physical happening to eyewitnesses other than some reported cases of mild radiation poisoning, presumably from the shimmering fields of the holograms. Most Apparition type encounters usually end with the being simply dissappearing into thing air or walking through a wall to evade pursuit. They are almost universally encountered alone, without any others of their type around.
Hybrids
Many UFO abductees have reported aliens that seem half Gray alien and half human, perhaps the end result of the apparent breeding programs that dominate accounts of Gray experimentations. They have large heads, but with hair, and while their noses, ears and mouths are more pronounced, the eyes are large like the Grays. The overall build is not as fragile as that of the Grays, but not quite as rugged appearing as a human. By nearly all accounts, they do not talk, and most do seem possessed of some psychic powers. Skin color tends to be much fairer than the Gray alien, but not quite of human pigmentation either. Skin texture seems to be human in nature without the webbing or mesh traits of the Grays.
It is important to note that these Hybrid types are almost always found in the company of the Grays aboard spacecraft, often used to calm frightened abductees and in many cases to have sexual relations with them. No cases to our knowledge have ever placed the Hybrids outside of the ships they come in, the reason communicated for this that they are too fragile or would be at risk on our planet. In no cases do the Hybrid aliens seem to be in control of things, and aside from calming and mating, seem to have no actual purpose in the running of the ships or in the experiments.
The Roswell Aliens
These aliens, named after the most famous UFO crash in the world, and are the subject of some debate among ufologists. Many experts insist they are a separate race from the others reported, while others support the belief that they are Grays whose description has been watered down or "humanized" over the decades. If reports from witnesses in the Roswell incident (actually a misnomer since the alien bodies were supposedly recovered near Corona, New Mexico some 40 miles Northwest of Roswell) are to be believed, these aliens were four feet in height, possessed of slim hairless bodies like the traditional Gray would be described. However, their noses and mouths seem to be larger, and some accounts even have the surviving aliens crying out or talking. The eyes are described as dark and pupiless, but closer together the way a human's would be. Clothing seems to be of a bright silver suit easily recognizable as such, and the hands of these beings are possessed of four fingers, with many small suction cups just under the ends of the fingers.
Aside from the infamous incident, few reports of the Roswell aliens have been reported.
Light
Some UFO cases involve beings of pure light, usually in the form of balls that hover several feet off the ground, are hard to look directly at, and communicate by telepathy. Given the fact that many of these encounters take place in remote swamps and fields at night, a direct comparison has often been drawn between these beings and the mythical will 0' wisps of Northern Europe. Like the dwarfs or goblin aliens, these balls of pure light seem more bent on frightening witnesses than any form of scientific investigation like the Grays, the Reptiles or to a less extent the Nordics.
Insectoid
This class of alien has been reported only rarely in witness accounts, though it is very widespread in science fiction tales dating back to Jules Verne. Insectoids are so called because of their insect-like appearance and have been described often as a human-sized preying mantis, only with longer forearms with "hands" capable of manipulating tools. Again, reports on this type are sketchy at best, and no generalities of their behaivior or attitude toward abuductees (assuming, of course, they do abduct humans) can be drawn.
