Since "The Greys" are a core part of Ufology I thought I would lay out the three main types that Ufologist agree upon.Each type has been reported numerous times in abduction accounts,military accounts,etc.Apparently the Greys come mainly from one of two different star systems;The Zeta Reticuli system and the Orion system.In addition to these three main types it is also reported that there could be as many as 22 variations including 'hybrids','The Orange',and the 'Bellatrix Mercenaries'.Apparently(or it is hypothesized) the Greys have been coming here for a long time and might not be the only race,also it is rumored that multiple world governments(mainly the United States) has long ago entered into a treaty with the Greys.The first widely believed treaty was signed by former President Eisenhower at Edwards Air Force Base is 1954 and was called the

Type A: COMMON GREYS.
This is the most common type. They are about four to four and a half foot tall, with large heads and wraparound eyes, a slit mouth and no visible nose.
In spite of the apparent physical similarities, the group of Type A Greys actually consists of several different species of Greys, that aren't necessarily related, and that come from different parts of our Galaxy. The Zetas, e.g., come from the Reticulum constellation, and are believed to be of a humanoid descent, whereas other races, e.g. those coming from Draco, Orion and Ursa Major, are believed to be reptilian species.

Type B: TALL GREYS.
Quite often the greys of Type A and Type C are accompanied by one or more greys of Type B: the Tall Greys. The Type B greys look very similar to the Type A greys, but they are a lot taller. Often abductees refer to these Tall Greys as 'the doctor,' because they seems to be in charge of the medical procedures taking place during the abduction event.
Two separate types of Tall Greys are known:
B1) the 'large nosed' tall greys, or the "Eban." They are 6 to 9 feet tall and are believed to come from the Betelgeuse system in the Orion Constellation.
B2) the common tall greys: They are 6-7 feet tall, and are basically taller versions of type A or C, even though sometimes they are said to have reproductive organs. They also seem to have something that resembles a (small) nose. They are believed to come from the same constellations as the Type A and C greys.

TYPE C: SMALLER GREYS.
Sometimes people also mention greys of Type C. The Type C greys are the shortest, about three and a half foot tall. They are believed to be the most dangerous of all grey species. They come from Rigel (per J.D. Stone, V. Valerian) and Bellatrix in the Orion constellation, and are saurian / reptilian in nature.

OTHER GREY SPECIES
This classification in 3 types is a simplification of the actual situation. V. Valerian has done extensive research in these matters and distinguishes up to 22 different types of greys. Other Grey species that have been encountered too are, e.g.:
- The Orange (see: 'Orange, The')
- The Bellatrix mercenaries: a genetic hybrid race between reptilian greys and insectoids, engineered solely for war-faring purposes.
Several sources also mention all kind of hybrid humanoid/Grey races. (See, e.g., 'Essassani').
It should be noted that not all authors are convinced that all Greys are extra-terrestrials. John Mack, Jacques Vallee, Withley Strieber and Graham Hancock, e.g., point at the similarities between the abduction realm and the realms of the fairies and the spirit world that shamans visit. They suggest that greys may be part of a parallel realm or another dimension that has always existed and that always had interaction with our reality.
It should also be noted that it is perfectly possible that if such realm exists, that extra-terrestrials might use it to travel to Earth. This indeed is what Shamans all over the world claim. Shamans in Latin America and sangomas in Africa even make a clear distinction between the inhabitants of the other realm, and the aliens that use that realm to come and visit us.
Last but not least: a) remote viewers who tried to discover where the greys are coming from mention that they are coming from three different time eras, i.e. that most of them are coming from different times in the future.
b) some authors believe Greys are not aliens but future humans or future humanoids.
c) some sources mention a "cyborg" type of grey: a small grey that seems to be partly biological (and presumably cloned) and partly mechanical. The remains of some of these would have been found at crash sites.

At least two, probably three, alien races have been called "The Orange".
1. The Orange would be a reptilian or a hybrid reptilian species. Some think they may be a hybrid sub-species of the greys. One whistleblower, though, claims to have seen documents that state that the Orange are the ones that created the smaller Greys.
The Branton material: "They are said to be "based below the west slope of Mt. Archuleta near 'the Diamond'. Some suggest that the 'Orange' are a so-called 'hybrid' race with PARTIAL reptilian-like features yet possessing human-like reproductive organs and even certain artificial or cybernetic features. It is possible that the 'Orange' consist of hu-brids and re-brids in that some or most of them may possess a human soul- matrix and therefore may be 'human', although information on the 'Orange' is presently sketchy. They have also been described as being involved in the scenarios taking place in the tunnels below the Nevada Military Complex as well. William Cooper briefly mentioned the 'Orange' based on memories of top secret documents he had read while in Navy Intelligence: (...)"
Note that other sources, too, confirm the existence of bases with Orange residents.
The Branton material adds that "The 'Orange' -- which sources seem to indicate 'may' actually be a double term used to describe two different types of entities, a reptilian hominoid group with scaly orange skin and a more human-like group with 'red' hair -- may have established themselves in Orion or Barnard's Star."
Other sources, too, locate this reptilian "Orange" race in the Orion system (and confirm that they are related to the Greys). One source, however ("Matthew") says these reptilian hybrid "orange" are from Sirius. (?)
Also note that the alien pictured on Whitley Strieber's Communion looks like an "Orange."
2. As indicated in The Branton material, the "Orange" is also used for a race of "red haired humans" that would come from Barnard's star. It's not clear whether this would be a separate race, or whether these are the same as the Lyran Redheads, mentioned below.
Continued............

3. The Lyran Redheads are one of the many races that originated in the Lyran constellation.
Lyssa Royal: "Their hair was red to strawberry blonde in color. The skin tone very, very fair; these entities had a difficulty exposing their skin to certain frequencies of natural light, due to the planet they sprang from. Some of these were also giant in stature, though there were some who were average human size. Eye color was generally light to what you would now consider green, though it is a different quality of green than you see upon your world. These entities were some of the first Lyran pioneers. (Pioneers is a very kind word, for there are many worlds that consider the red-haired ones to be the invaders, marauders and the basic havoc-wreckers of the Lyran genotype)."


A lot of people aren't to familiar with this reported species so I thought I would touch on them as well.

Hybrids of A Human Kind

or

"A hybrid is anything derived from heterogeneous sources or composed of elements of different or incongruous kinds. The hybrids spoken of in UFO literature are primarily a cross between Earth human and Zeta Reticuli beings. The specific process that is used to create these hybrids has not yet been revealed. It uses not only genetic splicing and cloning, but a form of light plasma engineering technology with which humans are unfamiliar." (PoL)
Known types of hybrids, thus far:
Grey / human
Essassani: Orion Greys and humans
Bellatrix mercenaries: reptilian greys and insect-like beings
hybrid ELs: physical humanoids and non-physical ELs
Orange: according to the Branton material a cross between humanoids and reptilian greys
Procyon: Blonds from Procyon would have cross-bred with earth humans

Hybrids are a major part in the Grey saga of Ufology as it is commonly believed that is the Greys true purpose,to combine the best of them and the best of us in order to save their dying race.A large number of abductees report genetic experiments done on them while on board the ship(like sexual implantation,fetus extraction,blood tests,etc).Also it is reported that the Greys have a major genetics laboratory in co-op with dark factions of Earth humans(NWO?) underneath Dulce,New Mexico.For more on the Dulce Base see

Bellatrix (Gamma Orion) is one of the main stars in the constellation of Orion, and lies at a distance of approximately 112 light years. It is seen from the Northern hemisphere on Earth as the right shoulder of the Hunter. This system is the home of dynoid and reptoid civilizations, or, to put it in other words, of lizzies and reptilians. It is also said to be the home of several species of Greys. (Types A, B and C. Type C is apparently only found in the Bellatrix and Rigel systems).
The negative image people sometimes associate with Orion mainly has to do with Bellatrix (which is Latin for 'fighter' or 'warrior'). The lizzie-inhabitants of the Bellatrix system focus upon expansion and colonization. Other keywords to describe its civilization are oppression and control. They have an extremely advanced technology. Stories about abductions and implants as controlling devices that are linked to Orion, nearly always have to do with Bellatrix.
The Branton material mentions "a huge colony of hybrid Reptilian-insectoid mercenaries, the result of Reticulan genetic engineering" in the Bellatrix system. It also mentions a lizard-like race, "snake men," as well as a dinoid civilization.
Bellatrix also functions as a link between the Orion Empire and the Draconian Empire
