M113 creature - Last of its kind - Sharon GimpelM-113 Creature; (left) Planet: M-113. The last of a vaguely humanoid species sometimes referred to as the "salt vampire" because of its need for salt and its willingness to kill to satiate it's own hunger. The creature is now extinct. TOS "The Man Trap" 1-1

Mirasta Yale - Malcorian scientist who first invented the warp drive - Carolyn SeymourBerel - Malcorian in charge of the medical facility - George HearnMalcorians; (right) Planet: Malcor III. Humanoid race, physically distinguished by mitten-like hands and feet -- suction cups at the palm and "fingertips" replacing digits -- and a cranial lobe with an upper set of olfactory nasal openings. Internal distinguishing features include a higher digestive tract, placed where a human heart would be and the Malcorians have more ribs -- three on the right and four on the left. Like humans they come in a variety of skin tones, from dark to fair, and perhaps a little like humans of the late 20th Century, the Malcorians immediately assume both a curious stance and an aggressive stance upon discovering that outsiders have infiltrated their world. Their technology approximates that of late 20th Century Earth, while their ideology is based on an almost medieval ethnocentrism. They assume their own superiority and believe in their aloneness in the center of their universe. Despite encouragement from an enlightened scientist, the Malcorian chancellor in 2367 decided to wait for more education before further contact with the Federation, asking not to be visited again. TNG "First Contact" 4-89

Controller Emck - captain of Malon vessel carrying radioactive waste to the void - Ken MageeMalon; Relatively little is known about the Malon; there has been no formal contact with the Malon government as such, merely a series of accidental encounters with their ships. Since these encounters have occurred over thirty thousand light years apart, it is possible that Malon territory extends across these kinds of distances - making their space far larger than the Federation. However, the Malon are known to have access to at least one stable "spatial vortex" - apparently a form of wormhole. It is possible that they have access to others which allow them to cross large distances, or even that are able to build such phenomena themselves. At this point in time we simply do not know.
At least some aspects of Malon technology produce large amounts of Theta radiation, and the Malon dispose of this by dumping it in unpopulated areas of space. The amounts involved are such that this has caused significant levels of pollution, endangering several species. It is the freighters involved in this operation that the U.S.S. Voyager has encountered. On their first meeting in early 2375, Voyager offered the Malon technology which would eliminate their Theta radiation problems. Unfortunately the Malon still appear to operate a profit based economy; since the waste dumping business would be totally destroyed by such technology, the Malon crews have been less than receptive to this idea. Several weeks later a Malon freighter attempted to steal an advanced probe belonging to Voyager, prompting the Starfleet crew to build the Delta Flyer to retrieve the probe first.
Later in the same year, Voyager encountered an abandoned freighter and recovered two crew members from nearby escape pods. This encounter allowed the crew to learn much more about the Malon. The freighters can carry enormous amounts of the toxins, over twelve trillion isotons on a single vessel. Should such a ship be destroyed it would devastate everything within three light years of the explosion. Their freighter crews generally suffer serious cell damage from their exposure to the Theta radiation, which they call 'freighter blight'. The Malon use analeptic compound injections to counter the freighter blight, but while the treatment keeps them alive it does not prevent skin scarring.
A crew member will typically work six months of the year on a Malon freighter; the exposure so received is expected to cut his life in half. The core laborers who work closest to the waste receive the greatest dosage; less than one third are expected to survive any given trip, but they make more money in two months of working than most Malon earn in a lifetime. Occasionally the radiation causes core laborers to experience mutations, and the Malon have many stories of 'monsters' which attack crew members or damage ships. Voyagers crew encountered one such individual on board the abandoned freighter and were forced to kill him in order to prevent the ship from being sabotaged. VOY "Night" 5-95

Mari; A race of telepathic beings, who have forbidden violent thoughts as well as actions. VOY "Random Thoughts" 4-78

Marijnians; Origin: in low orbit around Marijne VII. A sentient species, indigenous to subspace, yet in appearance, only like tiny chemical flames floating through space. Due to an accident in 2370, several of these beings became trapped in a ship and needed to communicate with humans. The Marijne beings communicate by directly accessing thoughts which proved deadly to humans, so in order to communicate, the beings instead assumed the image of a familiar humanoid in an effort to find their way back to the safety of their home in low orbit around the planet. Telepathic subspace creatures who appear to humans as fire and live in lower depths of gas giant Marijne VII. A group, accidentally trapped Walter Granger - Leader of the Mariposan clones - Jon de Vriesaboard the Raman, tried to communicate with its crew of seven when it ascended from their eco-level and they died from the contact. One took the form of Geordi's late mother to talk to him when interfaced with a remote probe, with the contact not fatal due to his remoteness. TNG "Interface" 7-155

Mariposans; (right) A cloned race of scientists descended entirely from the five survivors-the "Progenitors"-of a colony ship in the 22nd Century; they abandoned sexual reproduction due to their limited gene pool and found it repugnant being reunited with the lusty Bringloidi, their original shipmates, in 2365 to avoid the 15-generation limit of replicative fading. TNG "Up The Long Ladder" 2-44

Asoth - Markalian who complained about the food at Quark's - Bo ZengaMarkalians; (left) Humanoid and spacefaring race who often frequent DS9, distinguished by a bald head, no visible earlobes, and small stubby spikes about the face. Natives have included the smuggler Regana Tosh and Asoth. DS9 "Hippocratic Oath" 4-76

Mathenites-61A; Planet: name unspecified. A neutral race who agreed to provide asylum to Legate Ghemor after his rescue with Major Kira. DS9 "Second Skin" 3-51

Mazar; Alpha Quadrant planet and the homeworld of the Mazarites. In 2152, the Enterprise NX-01 was ordered to pick up Vulcan ambassador V'Lar on Mazar. V'Lar was on a mission to expose corrupt government officials, but when her plan was exposed, the Enterprise found itself being chased by Mazarite ships. ENT "Fallen Hero" 1-23Medusan Ambassador Kollos

Medusan; (left) Highly intelligent non-corporeal life forms with highly ordered minds. Members of the Federation, they cannot be viewed by humanoids because optical and electromagnetic patterns emitted by their physiology causes violent psychosis in humanoid neuro-physiology. Some races such as Vulcans can view them with special protective optic visors. As long as they are kept in special shielded containers, they can coexist with humanoids. They are highly skilled navigators and programmers. TOS "Is There In Truth No Beauty?" 3-60

Melkotian - appeared to Kirk explaining the death penalty - Abraham Sofaer as Melkotian voice

Melkotian; (left) Powerful non-humanoid race from the Melkot system. Preferring to remain secluded, their homeworld is surrounded by a series of warning buoys. Intruders are subjected to an elaborate telepathic execution involving illusion from the victims' own memory. Diplomatic relations were opened in 2268 and the Melkotians have since become full members of the Federation, but generally prefer seclusion. On Melkot there are only a few humanoid cities for outsiders. Melkotians appear as large brains covered by vital organs with two eyes in the front and short tentacles hanging from the bottom. They move and communicate with Psi abilities. TOS "Spectre of the Gun" 3-61

Menk; Humanoid species indigenous to the planet Valakis. The seemingly primitive Menk are one of two species on the planet; the other is the technologically-advanced Valakians. The Menk are subservient to the Valakians, but are immune to a disease currently Mudd Android - Alice series - Rhae and Alyce Andreceravaging the latter species. Dr. Phlox observed that, while the Valakians are being picked off by the disease, the Menk are in the process of an evolutionary awakening, and will eventually become the dominant species on Valakis. ENT "Dear Doctor" 1-14

Mudd Android; (right) Sentient humanoid androids originally from Andromeda. They settled on a class K world around 150 years ago. They gained their name from Harcourt Mudd, the 23rd century con man who found them. With around 10,000 members, the androids generally stay on their homeworld where they operate a subspace relay station and resort community. Several dozen androids travel the galaxy at large learning about our civilization for the entire community. It was with the precedent of the Mudd Androids that the Soong-Type Androids were considered true sentient androids. TOS "I, Mudd" 2-37

Melthusians; The otherwise unspecified race of Captain Bela Tyken, who first discovered and escaped from the energy-draining spatial anomaly named for him. TNG "Night Terrors" 4-91

Seltin - Elder or Leader of corporial Meridian - Christine HealyMeridian; (left) Class-M planet located in the Trialus star system in the Gamma Quadrant. Meridian underwent dimensional shifts every 60 years, causing its inhabitants to phase between corporeal and noncorporeal states. In 2371 the U.S.S. Defiant's crew assisted the Meridian's search for an answer to their unstable world. It was discovered that their sun's core fusion was imbalanced and a building cascade reaction at the quantum level was triggering the dimensional shifts. The sun's reactions were stabilized, enabling the planet to exist for longer periods in solid form. DS9 "Meridian" 3-54

Menthars; Planet: Orelious IX. An ancient species, now extinct and thought to be both inventive and very resourceful when in battle. Several battle strategies which are still used originated from the Menthars (the Kavis Teke elusive maneuver and a passive lure strategem comparable to one of Napoleons'). Their entire race died out over a thousand years earlier because of a devastating war against the Promellians which extinguished both sides, and destroyed the planet. TNG "Booby Metron - tells Kirk that we might grow up - Carole ShelyneTrap" 3-54

Metron; (right) An extremely advanced humanoid species who intervene in Captain Kirk's battle with the Gorn on Stardate 3045.6. Being surprised at the mercy Kirk shows to the Gorn, the Metron indicates that in perhaps a thousand years, they will be ready to make contact with the Federation. TOS "Arena" 1-18

Mikulaks; Humanoid race with devotion to the biological sciences. While they have achieved advanced space flight only in the past few decades and lag centuries behind in some aspects of modern technology, Gem - Mute Minaran who saves McCoy and her entire civilization - Kathrine Hayestheir biotechnology is admirable. They have highly developed genetic and pathological technologies and are sometimes sought for their help in epidemiology. This technology stems from a viral plague that almost destroyed their race a century ago. Their space technology was delayed as all efforts were aimed at biological research. TNG "Hollow Pursuits" 3-69

Liko - Mintakan who encountered Picard - Ray WiseMinaran; (left) Individual whose nervous system is capable of absorbing the physical and emotional responses of another, permitting the empath to heal the injuries of others by transferring those injuries onto her or his own body. TOS "The Empath" 3-67

Mintakan; (right) Bronze age proto-Vulcan humanoids; natives of the planet Mintaka III. They were reported to be very peaceful and rational, Ah-Kel - Randy Ogelsbyliving in a matriarchal, agricultural society. A Federation anthropological field team, studying the Mintakans in 2366, accidentally exposed the Mintakans to advanced Federation technology. TNG "Who Watches the Watchers?" 3-52

Miradorn; (left) Reptilian humanoids from an unknown planet. Little is known about them except that they are born in telepathically linked twins that are considered to be two halves of one being. If one is injured or killed, the other will relentlessly seek vengeance for what he perceives as an assault against him. DS9 "Vortex" 1-12

Covar Tholl - Mizarian captured by aliens along with Picard and a Chalnoth - Stephen Markle

Mizarian; (right) Humanoids from Mizar II. With a gray wrinkled complexion and no body hair, they generally wear light gray or tan robes in public. With a firm belief in pacifism, they have been conquered six times in three hundred years. They have no political alignments and the Mizar system is generally considered to be neutral territory. TNG "Allegiance" 3-66

Augris - Third Magistrate of the oppressive regime known as the Mokra Order - Alan Scarfe
Mokra; (left) The Mokra Order rules their planet, with the Alsaurians treated as a sub-class. The alien race claims to be "helping our Alsaurian neighbors defend themselves against common enemies." Naturally, the Mokra have military control of the planet. VOY "Resistance" 2-28

Moneans; VOY "Thirty Days" 5-103

Morg - male of the species of Eymorg - James DarisMorg; (left) Term used for the male population on planet Sigma Draconis VI. The Morgs lived under virtual Stone Age conditions, controlled by the Eymorg women and their Controller. The Morgs and Eymorgs were reunited as a single society after the failure of the Controller in 2268. TOS "Spock's Brain" 3-56

Moropa; Violent humanoid race from system just outside the Bolarus system.

Since their weapons technology is over a century behind the Federation, their dreams of conquest were destroyed immediately after entering space. They do have a longstanding hostility with the Bolians of the Bolarus system. The Moropa are generally average humanoids except for a blue tinted skin indicative of nickel-based blood. TNG "Allegiance" 3-66

Mugato - Janos ProhaskaMugato; Planet: Tyree's planet. An indigenous simian-like beast, carnivorous, with characteristically white fur, a rhino-like horn on the top of its head, and sharp and extremely venomous fangs. TOS "A Private Little War" 2-48
