'''Tallon Metroids''' are a variation of [[Metroid (species)|Metroid]] that developed on [[Tallon IV]]. There are multiple differences between these and regular Metroids, which stem from developing on different planets. Unused design notes indicate that this environmental versatility is due to a Metroid's ability to adapt to survive in differing atmospheric and gravitational conditions, and varying gamma radiation levels.<ref>{{Cite web| quote=Theoritical analysis suggests that the Metroid's environmental versatility is due in part to it's adaptness to survive in differing atmospheric conditions, marked changes in gravitational influence, and varying levels of gamma type radiation.| url= http://frogskull.blogspot.com/2008/02/metroid-prime-3-corruption-art.html| title= Frog Skull: Metroid Prime 3: Corruption Art| site= Frog Skull}}</ref> These Metroids were introducted to these new environments by [[Space Pirate]]s who were studying them for various purposes.

Tallon Metroids are the main type of Metroid encountered in ''[[Metroid Prime (game)|Metroid Prime]]'' and ''[[Metroid Prime 2: Echoes]]''. Tallon Metroid specimens are also mentioned in ''[[Metroid Prime 3: Corruption]]'', though these are not actually interacted with in an non-mutated state at any point in the game.

==History==
===Relocation and Study===
[[file:Tallon Metroid 01.jpg|thumb|left|250px|Samus encounters a Tallon Metroid.]]
Metroids were first brought to Tallon IV from [[Zebes]] by Space Pirates.<ref name=MetroidStudies>{{cite|Initial transfer of Metroids to Tallon IV research facilities has been completed. Three were terminated in an incident at the landing site, but the others were pacified and transported safely. Initial Phazon infusion testing is under way. We are eager to observe the effects of Phazon on Metroids, especially their ability to absorb and process the energy give off by Phazon sources. Early research suggest a considerable growth in power and size. Whether the creatures will stay stable thereafter remains to be seen.|[[Space Pirate Data]] - "Metroid Studies"|Metroid Prime}}</ref> Their research frigates transported these Metroids to their [[Glacier One|Research Headquarters]] in [[Phendrana Drifts]] where studies began on their ability to harvest bio-energy.<ref>{{cite|Zebes has fallen. All ground personnel are presumed dead, either killed by the Hunter clad in metal or in the subsequent destruction of the underground facilities. Our research frigates [[Frigate Orpheon|Orpheon]], [[Frigate Siriacus|Siriacus]] and [[Frigate Vol Paragon|Vol Paragon]] were in orbit at zero hour and managed to retreat. Frigate Orpheon is now docked at [[Vortex Outpost]]. Orpheon's cargo appears to have a 100% survival rate; Metroids are healthy but on restricted feeding schedules due to uncertain supply status. We are ready to begin research on the Metroids and other promising life-forms. Security status remains at Code Blue; no signs of pursuit from the Hunter.|[[Space Pirate Data]] - "Fall of Zebes"|Metroid Prime}}</ref> Developing in the unique environment of Tallon IV created the Tallon Metroid strain used in Space Pirate experimentation.<ref name=variations/> Preliminary interests in Metroids included potential domestication for use as weapons or power sources.<ref>{{cite|Studies of Metroid biology continue, though with limited progress. It seems likely that we will be much more successful using the Metroids for our means rather than trying to reproduce their powers. If they could be adequately tamed, we would have no need of a proper understanding of their metabolism. A small force of disciplined Metroids could wipe out entire armies, and once we find a way to shield them from cold-containment weapons, they will be invincible. Furthermore, if we could then harvest the energy they'd consumed, we would have a near-limitless source of power at our disposal.|[[Space Pirate Data]] - "Metroid Forces"|Metroid Prime}}</ref> Their aversion to [[Ice Beam|sub-zero temperatures]] was utilized by the Pirates in their studies, who often used cold containment below 10° centigrade and ice containment gear to render the test subjects docile.<ref>{{cite|Sub-zero temperatures have made the Metroids sluggish and easy to control, even those well into Phazon infusion cycles. Cold containment status are sufficient for the juveniles, but some of the larger Metroids have been moved to quarantine caves for safety purposes.|Scan Data|Metroid Prime}}</ref><ref>{{cite|Metroid containment fields appear 100% effective after adjustments. Temperatures below 10° centigrade will render Metroids docile.|Scan Data|Metroid Prime}}</ref><ref>{{cite|All guards must use ice containment gear when transporting Metroids. This includes sedated specimens and those pronounced dead.|Scan Data|Metroid Prime}}</ref>

Discovery of the mutagenic substance [[Phazon]] on Tallon IV prompted a series of Phazon infusion experiments in organic and inanimate objects, including Tallon Metroids.<ref name=MetroidStudies/> Phazon mutations resulted in heightened immunity to cold dampening fields,<ref>{{cite|Hunter Metroid ds is showing signs of increased instability and a heightened immunity to cold damping fields.|Scan Data|Metroid Prime}}</ref> mass increase,<ref>{{cite|Phazon Infusion, Stage 6.

The Space Pirates developed [[Synthetic Metroid Rations]] to sustain Metroid test subjects, but Metroids were unresponsive and required bio-energy sources for nourishment.<ref name=syntheticrations>{{cite|Metroids are not responding to synthetic sustenance. We have reason to believe they only gain nourishment from active bio-energy sources.|Scan Data|Metroid Prime}}</ref>

===Aetherian Studies===
[[file:Tallon Metroid (Aether).png|right|150px]]
Tallon Metroids were later transported to the planet [[Aether]] and studied there. The epidermis of Tallon Metroids raised on Aether had a red pigmentation, but they were otherwise identical. In addition to using them for bio-energy production, the Space Pirates made several attempts to domesticate Metroids. These attempts ultimately failed, and led to the termination of several untamed subjects and handlers.<ref>{{cite|Termination Report 07.195.02<br>Metroid unit 318 was put down today after a failed domestication session. Metroid unit refused commands and terminated one of its handlers before it was subdued.|Scan Data|Metroid Prime 2: Echoes}}</ref><ref>{{cite|Training Report, 07.200.08<br>Science Team believes the Metroids can be trained. After several cycles of trying, I believe Science Team has vapor for brains. I've lost two assistants to the wretched little things.|Scan Data|Metroid Prime 2: Echoes}}</ref>

The Space Pirates began mass breeding programs for Metroids here,<ref name=breeding>{{cite|Production Report-Metroids 07.201.01<br>Mass breeding of Metroids under way. We will meet Command's quota within a cycle. Storage remains an issue, recommended expansion of existing facility before a critical Metroid level is reached.|Scan Data|Metroid Prime 2: Echoes}}</ref> and designed organic [[Metroid Cocoon|cocoons]] to be used in transporting [[Infant Tallon Metroid]]s. Containment and handling of Metroids on Aether became increasingly abusive: subjects were harvested of their bio-energy to the point of cellular degeneration,<ref>{{cite|Bioscan complete.<br>Metroid subject has been energy-drained repeatedly over the last 3 cycles. Subject's cellular structure has become unstable as a result.|Scan Data|Metroid Prime 2: Echoes}}</ref> confined in containment fields that prevented them from entering sleep cycles,<ref>{{cite|Bioscan complete.<br>Containment field is keeping Metroid subject in a constant state of agitation.

He should be regaining brain functions in a cycle.|Scan Data|Metroid Prime}}</ref>

Metroid Handling Protocols dictated that Metroids were not to be used for target practice or domesticated as pets.<ref>{{cite|Metroid Handling Protocols, 07.202.02<br>Metroids are not pets. Metroids are not for target practice. Finally, unauthorized feeding of Metroids is still strictly prohibited.|Scan Data|Metroid Prime}}</ref> The desire of Space Pirates to use Metroids for personal companionship may have stemmed from their inability to keep usual domestic animals, such as [[Gronkat]]s and [[Olbap]]s, due to their susceptibility to [[Phazon Corruption|Phazon madness]].<ref>{{cite|The keeping of pets has been suspended until further notice. Domestic beasts have been deemed highly susceptible to Phazon Madness, and are therefore a hazard to personnel. All Gronkats and Olbaps must be disposed of immediately. Failure to comply will result in the loss of pay for a cycle and reduced rations.|Scan Data|Metroid Prime}}</ref> Some Pirates apparently became attached to Metroid specimens in spite of protocols and even fed them pet treats, though these caused food poisoning.<ref name=foodpoisoning>{{cite|Bioscan complete.<br>Metroid subject is suffering from food poisoning. It has ingested several pet treats and Space Pirate rations. These do not agree with its digestive system.|Scan Data|Metroid Prime 2: Echoes}}</ref>

[[Dark Samus]] was suspected of stealing several Tallon Metroids from Space Pirate facilities.<ref>{{cite|Theft Report 07.196.05<br>Three Metroids have been stolen. All on-duty units have been questioned. Whereabouts of Metroids unknown. Doubling security in Metroid areas until further notice.|Scan Data|Metroid Prime 2: Echoes}}</ref><ref>{{cite|Security Report 07.199.07<br>The Dark Hunter was spotted near the Metroid tanks. She attempted to breach the containment racks without success, then escaped. Perhaps she is behind the Metroid theft.|Scan Data|Metroid Prime 2: Echoes}}</ref>

===Pirate Homeworld===
There is also evidence that Tallon Metroids were studied on the [[Pirate Homeworld]].<ref>{{cite|Data decoded. Tallon IV specimen. Subject has been returned to its original research facility.|Scan Data|Metroid Prime 3: Corruption}}</ref> A Phazon enhanced variant of the Tallon Metroid strain, called [[Phazon Metroid]]s, are encountered on the Homeworld and other planets during the events of ''Corruption''.

Pirates and Dark Samus seems to have used these Phazon Metroids to attack the ''[[G.F.S. Valhalla]]'' and steal [[Aurora Unit 313]] on board. Phazon Metroids remain there through the end of the events in ''[[Metroid Prime 3: Corruption]]''. Assuming that they remain there without being bothered, they would eventually die of starvation after draining life forms on the ship.

==Biology==
===Differences from Metroids===
Differences in Metroid strains appear as a result of development in different planetary conditions.<ref name=variations>{{cite|Observations on Metroid native to different planets display subtle variations in biological processes.|Scan Data|Metroid Prime 3: Corruption}}</ref>

Tallon Metroids are smaller than regular Metroids, and significantly weaker. While a Metroid takes five [[Missile]]s while frozen to kill, a Tallon Metroid only takes one. Tallon Metroids can also be destroyed by physical stress from gorging on bio-energy and by conventional weaponry. Tallon Metroids, like regular Metroids, can also be shaken off of Samus by a [[Morph Ball Bomb]] detonation. Although Tallon Metroids are weaker in their mature states, the variants created by Phazon mutation are stronger than a regular Metroid.

The Tallon Metroids that were taken by Space Pirates to [[Aether]] are red in color, but are otherwise identical to Tallon IV-raised Tallon Metroids.

While regular Metroids hatch from eggs laid by a [[Queen Metroid]], Tallon Metroids appear to reproduce another way. The Space Pirates on Aether, who did not appear to possess a Queen Metroid, conducted a mass breeding program,<ref name=breeding/> and the subsequent [[Infant Tallon Metroid]]s were stored in artificial organic [[Metroid Cocoon|cocoons]]. The Tallon Metroid reproductive process is not divulged in ''Prime'' or ''Echoes''. It is possible that Tallon Metroids were reproduced by some unnatural means by Space Pirates.

===Morphology===
[[File:Tallon Metroid (gold).png|right|150px|Tallon Metroid artwork]]
A Tallon Metroid consumes raw bio-energy from its victim using twin mandibles that are connected by means of energy conduits to the core of its quadripartite nucleus.<ref>{{cite|Metroid dissection continues to produce more questions than answers. Our research teams have isolated the energy conduits that run from the invasive twin mandibles to the energy core in the creature's quadripartite nucleus, but the manner in which the Metroid actually extracts the life force from its pray remains an utter mystery. The victim does not lose blood or any other vital fluids, and yet the Metroid extracts energy; identifying this energy is our central problem. It takes no physical form, and yet without it, the victim dies. We will continue to research this matter, as the isolation of this life-giving essence could be the key to our ascendance.|[[Space Pirate Data]] - "Metroid Morphology"|Metroid Prime}}</ref> This nucleus replaces the need for any other internal organs, so Tallon Metroids lack discernible sensory organs or cardiovascular system.<ref>{{cite|Internal organs of Metroid seem to be limited to nucleonic absorption cells and massive energy reservoirs.|Scan Data|Metroid Prime}}</ref> The apparent lack of a brain in Metroid physiology may imply that it is equipped with a decentralized nervous system; evidence implies that the quadripartite nucleus replaces the brain function, as Space Pirate data would suggest.<ref>{{cite|Metroid brain scan results in. Studies show accelerated activity in parietal lobe during hunting cycles above 10° centigrade.|Scan Data|Metroid Prime}}</ref> The nucleus is contained by a transparent epidermis to which the large mandibles are attached. Apparently, Metroids have the ability to ingest solid food and possess a digestive system, though these appear superfluous.<ref name=syntheticrations/><ref name=foodpoisoning/>

Absorbing energy causes a notable increase in size and mass.<ref name=mp2logbook/> The physical stress caused by gorging can be lethal, however.

===Life-Cycle===
====Infant Tallon Metroid====
{{Main|Infant Tallon Metroid}}
Tallon Metroids begin their life-cycle in this infant stage. They lack mandibles or the ability to absorb bio-energy from prey in this developmental form, but will still ram enemies if threatened. They mature at once if exposed to [[Phazon]] radiation.

====Tallon Metroid====
The mature Tallon Metroid stage is the preferred maturation level for Phazon-infusion experiments by Space Pirates. The protruding tentacles of the infant stage have hardened into mandibles and all energy-siphoning processes are functional.

====Hunter Metroid====
{{main|Hunter Metroid}}
Hunter Metroids are a highly aggressive, efficient form of Tallon Metroid that possess an energy-draining tentacle for use in long-range battle. Despite its apparent superiority to prior stages, a Hunter Metroid is still vulnerable to sub-zero temperatures.

==Variants==
===Fission Metroid===
{{main|Fission Metroid}}
Fission Metroids are no longer vulnerable to cold attacks. These are mutants that are capable of splitting into two that are vulnerable to only a specific type of beam. Their name stems from their biological ability to divide.

===Dark Tallon Metroid===
{{main|Dark Tallon Metroid}}
These are Tallon Metroids possessed by the [[Ing]]. They are vulnerable to the [[Light Beam]] due to their Darkling nature. They can still be frozen by the [[Dark Beam]], but it does not cause damage in itself.

===Phazon Metroid===
{{main|Phazon Metroid}}
Phazon Metroids are still vulnerable to cold, but are capable of shooting energy bursts and are able to "phase" through objects or shots.

===Design Notes===
The following design notes were written by the environment artist [[Matt Manchester]] to correspond with features put into the [[Metroid Processing]] chamber in ''[[Metroid Prime 3: Corruption]]''. Several of these reference Tallon Metroids or the phenomena surrounding the development of new strains of Metroids raised on different planets.

===="Failed Experiment"====
''Metroids exposed to the Dark Aetherian atmosphere displayed significant changes to their physiology and behaviorial patterns. Exposure resulted in altered cutaneous pigmentation, solidified carapace with superficial dermal striation, emergence of multiple luminescent ocular organs, and two additional cuspidate teeth. Advanced physical durability was observed, as well as more instinctual and aggresive behavioral tendencies. Subsequently nocturnal, Dark Metroid developed a fatally acute sensitivity to solar light. All attempts to recreate this atmospheric transformation have met with utter failure. Test specimens yield a 100% mortality rate. Experiments rarely live more than a few hours after artificial transformation is achieved. Of these rare instances, specimens require complete artificial sustainment. No sentient behavior has been observed in any instances. Failure attributed to unknown variables.''<ref>{{Cite web| url= http://frogskull.blogspot.com/2008/02/metroid-prime-3-corruption-art.html| title= Frog Skull: Metroid Prime 3: Corruption Art| site= Frog Skull}}</ref>

===="Machine Dissected Metroids"====
''Side by side observation of metroids native to different planets show subtle variations in dietary cycles, energy consumption abilities, and aggressive tendencies. Theoritical analysis suggests that the Metroid's environmental versatility is due in part to it's adaptness to survive in differing atmospheric conditions, marked changes in gravitational influence, and varying levels of gamma type radiation. Specimens native to SR-388 still display most consistent growth and energy consumption maturation.''<ref>{{Cite web|url= http://frogskull.blogspot.com/2008/02/metroid-prime-3-corruption-art.html| title= Frog Skull: Metroid Prime 3: Corruption Art| site= Frog Skull}}</ref>

===="Eggs Chamber"====
''Exposure of unhatched metroids to alien sustentative chemicals and levels of radiation has been insightful as to the adaptability and survivability of the organism, even at this early latent state. Specimens that survive have been observed with greater scrutiny as to their cumulative behavioral augmentations, as well as any affect exposure has to their ability to drain life energy.''<ref>{{Cite web|quote= |url= http://frogskull.blogspot.com/2008/02/metroid-prime-3-corruption-art.html| title= Frog Skull: Metroid Prime 3: Corruption Art| site= Frog Skull}}</ref>

===="Baby Metroids"====
''Metroids derive from a parthenogenetic birthing process. Amniotic egg fluid provides both nutrients and phsyical protection of the developing larva. Once hatched, this fluid experiences rapid desiccation, hardening completely in several seconds. Hatched Metroid larva still retain a full coelenterate body structure. Larval tentacles harden to become cuspidate teeth in adults. Energy draining abilities in this form are primitive, but still very fatal.''<ref>{{Cite web|url= http://frogskull.blogspot.com/2008/02/metroid-prime-3-corruption-art.html| title= Frog Skull: Metroid Prime 3: Corruption Art| site= Frog Skull}}</ref>

===="Individual Metroids"====
'''''Tallon IV specimen''' - One of a small batch of Metroid native to Tallon IV. This was the only group transferred from local research laboratories on the planet before their subsequent attack and destruction.''

'''''SR388 Specimen''' - Metroid recovered from Ruined structures excavated below the surface. The frequent presence of Chozodian architecture wherever Metroids are found to habitate naturally leads to theories of possible connections between the two species.''

'''''Zebes Specimen''' - Research laboratories located below the surface of Zebes consistently yield the most relevant data on Metroid developmental cycles, and physiological composition. This could be due to the vast changes of climate on the planet. Observations and tests may be performed in a multitude of naturally-occuring native environments. Progress of research on this site has led to Expansion of the labs, as well as a stronger security presence. The Zebes station remains our primary Metroid research station.''<ref>{{Cite web|quote= |url= http://frogskull.blogspot.com/2008/02/metroid-prime-3-corruption-art.html| title= Frog Skull: Metroid Prime 3: Corruption Art| site= Frog Skull}}</ref>
