MIZZARETTS

A non-corporeal energy-based species which inhabits inhabit the coronal haloes of O-spectra

stars and has developed a space faring civilisation, travelling the cosmos in field-enclosure ships. When encountering corporeal species, they usually use encounter suits aka Simulacrons which are tailored to look like a divine or idealised version of the species they interact with. When meeting humans, they look like golden greek gods, but act very mundanely.

Mizzarett have a commercial rivality with the Lamberj species. They are known to have colonies on Kimmonoshek.

OUTER SPACE MEN / MEN FROM PLUTO / PLUTONIANS / ELECTRON +

Planet of Origin: Pluto

Plutonians are a sentient species of energetic beings using plutonian matter to take shape and interact with the physical world, they have the ability to go bakc to their energetic form to travel great distances. It is unknown if they need plutonian conditions in order to assume physical shape elsewhere.

Men of Pluto action figures where commercialised in the sixties. Their story was told at the back of their blisterpack: 

The cold and desolate planet Pluto is too far from the sun ti derive its heat and, thus, the very atmosphere lies frozen and life as we know it cannot exist. But there, at the very edge of the Solar System, the great intergalactic winds that blow between the stars carry with them great mass of cosmic energy. In the beginning, this living energy bombarding the frozen planet did itself freeze to become living matter and, this, a might race of beings began. created of energy, they can become energy at will and Electron +, from his laboratory in Electra City, can transport himself throughout the universe as a beam of light.

WAVICLE SPORE / PLASMACYTES / BLOODWORM / SPARKLE DANCER

The creature commonly known as bloodworm or plasmacyte is the result of a deliberate mutation, presumably by the Regulans, a manipulation of creatures known as wavicle spores for waht is believed to be military purposes.

Wavicle spores were originally mostly harmless creatures, using oxygen only as a catalyst for tranformation in their next life cycle. After their mutation, when entering in contact with a redblooded creature, they turn to particles and, at certain level of concentration in an organism, transform into plasmacytes aka bloodworms, leech-looking creatures which feed aggressively on the blood of living organisms. In this state, the creature uses more energy eating than it gains by doing so and is therefore stuck in a loop in which what it eats only fuel its own appetite. They cannot really be killed, as destroying their form only shatteres them back into wavicles, ready to turn to particle when reexposed to blood. As such, the plasmacyte state could be considered a disease, one that can only be cured by reversing the mutation.

Without the mutation, wavicle spores would, when achieving a given level of concentration, turn into giant wavicle butterfly-like form refered to as Sparkle Dancers. It remains uncertain if in natural conditions, they would require an organic host to do so or just a sufficient amount of oxygen or other gas would suffice.

Source: Star Trek Universe. (Star Trek Phase 2: Blood and Fire) It remains uncertain that theinterpretation of the Regulan Bloodworm described aboce is canon to the official Star Trek universe. It nevertheless is now officially part of the pop culture related to that franchise thanks to the people at Star Trek New Voyages who made the creature pivotal to the Blood and Fire episode of their webseries. What is officially known about the bloodworm is that, under its plasmacyte state, it was native/discovered in the Regulan system. It has been described as soft and spineless. Medically, it has been known to be used medically under controlled conditions in the 22nd century for cleansing a being's lymphatic system. (ENT: "Doctor's Orders"). What the Blood and Fire episode (and the novel and TNG rejected episode it is based on) added to the lore was that the plasmacyte was developed by the Regulans as a biological weapon, that the leeches reproduced at an astronomical rate and wiped out the Regulans. Once left without nurrishment sources, they starved and shattered, reverting to their wavicle state until space explorer came to the Regulan system. As the wavicles appear to be able to survive in space, it remains unknown if, under their initial state, they were indigenous to the Regulan system or came to be there by other means.

COMPANION

Presumed planet of origin:  a planetoid in an asteroid belt located in the Gamma Canaris star system, less than 1000 ly from Earth, possibly a remnant of a planet breakup. It is one of 7000 bodies  in the asteroid belt, 34 % of which had some type of atmosphere. The composition of the planetoid is iron and nickel, and it had an atmosphere that consisted primarily of oxygen and nitrogen with traces of krypton, argon, and neon. The general surface temperature was 75 °F. Gravity was 1G.

Only one representative of this species is known. The Companion is a non humanoid lifeform  composed chiefly of ionized hydrogen and electricity. It appeared as a gaseous, vaguely sparkling cloud of yellow, orange, and red.It is able to communicate via telepathy with willing to do so. It has the ability to rejuvenate organic life, and inhibit the aging process, disperse or teleport itsel, produce material objects, including food and water and manipulate objects through telekynesis, produce electric discharges. It can also merge with a humanoid, creating a joined entity. In doing this, the creature sacrifices its immortality and most of its other powers.

DOUWD

The Douwd are a peaceful immortal extragalactic uncorporeal species, self-described as "beings of disguises and false surroundings". Through their uncanny psychic powers, they have the ability to create and destroy on an interstellar scale and maybe more. Although they can't bring people back to life, they can make illusionary recreations of them. Although seamingly nearly omnipotent, they are not omniscient.

One Douwd has been known to travel the Milky Way,sometimes under the form of a human in the course of the 24th century. During that time, he destroyesd the Husnock civilisation after they had wiped out a human colony on which he was living.

FIRE VAMPIRE / FTHAGGUA

Planet of Oirign:  Ktynga (or Norby's comet) a bluish comet that is currently near the star Arcturus. The comet is unusually hot and has strange properties, such as the ability to travel faster than light.

On the surface of the comet is a huge building wherein dwells the being Fthaggua and his servants, the fire vampires. Fthaggua and his minions can guide the comet to travel between the stars, searching for intelligent civilizations to feed upon and will visit the solar system four centuries from now.

The Fire Vampires are a gestalt non-corporeal species that resemble crimson bursts of lightning. They gain sustenance by draining energy from intelligent beings; the subject so affected bursts into flames as if experiencing spontaneous combustion. The fire vampires also absorb all memories from the targeted victim. Since the minds of the fire vampires form a collective "hive mind", all knowledge gleaned from a slain being is shared by every member.

Fire Vampire have a queen/regent entity which they serve and which is  refered to as Fthaggua. Fthaggua appears as an unsteady orb of blue flame. He is the high priest of Cthugha. Like his minions, gains energy and knowledge from the intelligent creatures they slay. With the knowledge so accumulated, Fthaggua and his minions can better plot their attacks on the sentient races of the universe, whom they regard as mere sources of food.

VAPORAN / VAPOR MAN

Planet of Origin: Vaporus, a planet which is part of the glalactic community in the 23rd century and even has some of its members in the Galactic Police.

The Vaporans are sentient green gaseous lifeform able to take on different shapes and assume different condensation states, becoming more or less solid and project different kinds of gas streams

SHIFT AGENT

Shift Agents were entities without solid bodies. They could transfer their energy into mechanical objects and control them. It remains unclear is Shift agents are natural lifeforms or engineered agents.

One Shift Agent is known to have come to Earth in 1885 to retrieve some dark matter. It briefly possessed a steam train in England.

FEARMONGER

The Fearmonger is an alien entity which fed off fear and hatred. It itself does not stir up fear, but chose hosts capable of stirring up large amounts of fear and stays with them for long periods, moving on if the host died. In addition to feeding off of fear, it can unleash mental bursts of concentrated fear on attackers, rendering them permanently insane with fear. When not inhabiting a host, it was vulnerable to any metal that can ground it, as its body was made of electromagnetic energy. 

According to some stories, an unknown alien civilisation created several psychic entities (each one personifying an emotion such as fear, compassion, pride, and anger) to incite group emotions and thus unite their people. When the civilisation fell, the entities left for other worlds. The entity responsible for fear eventually made its way to Earth.

It shares a lot of traits and history of the Redjac.

FAMILY OF BLOOD

The Family of Blood are green, gaseous sentient entities that can inhabit and possess human bodies and possess a unique sense, being able to track a scent over interstellar distances and even time period. They gather in family-based social cells or parents and children and spend their time hunting organic preys. They have very short lifespans, lasting only 3 months, but lend to their descendants technologies they've stolen from their victims. While in human form, the Family can telepathically communicate with each other from a distance. They also had access to their Hosts' memories, which enabled them fast understanding of stolen technologies but though have some difficulty assimilating personnality and pretending.

BODACH

The Bodach were incorporeal creatures who  fed on the energy produced by a mind when dreaming. They could emit psychic energy which would cause nightmares, allowing them to feed. This psychic energy could be blocked by aluminium. As the Bodach had no body, they were forced to control these sleeping people, using them to interact with their surroundings. The Bodach were known to the Celtic people, who believed they were evil spirits. At some point, an Obelisk was made with two crystal eyes. With these crystals, the Bodach would be able to send the whole world to sleep and feed on their dreams. In unknown circumstances, this did not come to pass, and instead the obelisk was buried outside what would be London. In 2050, the site was dug up and the obelisk destroyed shortly after.

REDJAC / JACK THE RIPPER / BERATIS / KESLA

The Redjac is a non-corporeal parasitic  lifeform that existed for centuries by journeying from planet to planet and feeding on the pain and fear he caused by committing serial murders. It  requires a host to inhabit in order to commit its crimes. It had many abilities, and can possess others and objects, even spaceship size ones.

One such entity seems to have existed on Earth from at least the 19th to the 22nd century.

It shares some characteristics with the Beta XII-A entity.

CALAMARAIN

The Calamarain are spaceborn intelligent, non-corporeal lifeforms that exist as swirls of ionized gas that emits Berthold rays (a form of deadly radiation that causes living animal tissue to disintegrate) when probing something but can also communicate through a sequence of tachyon emissions. They have the ability ot travel faster-than-light.

BETA XII-A ENTITY

Planet of Origin: unknown, but first encountered in the Beta XII-A system.

The Beta XII-A entity is a parasitic noncorporeal being composed of pure energy. The entity appeares as a small, circular pattern of multiple swirling lights in different colors, although it becomes red in hue and emitts a high-pitched wail when "feeding". It feeds on the emotions of hatred, anger, and primitive predatory instincts exhibited by sentient organic beings in close proximity to it. If those emotions are not present, the entity will try to spawn such feelings. It controls the instantaneous transmutation of matter from one form to another, can pass through solid objects at will, teleport from one location to the next, and influence the thoughts of others. It could heal an organic being's mortal wounds, and could even alter a person's memories. The entity appears unable to communicate in any fashion understandable to organic beings. Although its motives and nature are not wholly known, it lacks the same ethical standards of most humanoids and largely acts in a malignant fashion. Its only weakness appears to be exposure to emotions of humor, good nature, and friendship; it is particularly susceptible to laughter.
It shares several traits with the redjac entity.

GOD / CALCULATING GOD / ENTITY

A species or entity which is believed to have triggered orchestrated sychrone mass extinctions  (440, 365, 225, 210 et 65 millions years ago) on several worlds in Earth's vicinity (at least Earth, Beta Hydri 3, Delta Pavonis 2 and possibly Groombridge 1618) and might be doing it on a even bigger, even galaxywide scale  to promote the evolution of sentient life.

This species/entity looks like a pitchblack sphere some 1.5billion kilometres wide. is known to be able to contain the showckwave of a Betelgeuse-sized star going supernova and to give to species that it deems mature enough the know-how to fuse genetic materials from several species to produces a new intelligence able to live in space and whose essence will possibly be able to survive the Big Crunch and create its own Universe.
