Magenta Blood is the highest and rarest color of blood in the hemospectrum. Like their violet blooded comrades, they are sea dwellers and are considered royalty. Magenta blood is so rare that those who possess it are destined to be the sovereign of all trollkind.

The Tortuerer Imperious, Turnus Captol, and Devora Captol are the Magenta-blooded trolls in rule. Only 3 trolls at any time have had this blood color, an older one serving as the Empress or Emperor of the trolls and the younger ones known as the heiress or heirs to the Alternian throne; this is due to the Tortuerer killing any other Red Violets in existance in the past thousands and thousnads and thousands of years he has been alive. If any have made it out of childhood and challenge him, he may possibly offer them the chance to join his "family" and act like a child, but have no right to the throne. The only Magenta known to survive to this point and take the offer was Brihas Intono.

An Heiress or Heir may enforce an unknown but extensive amount of control over the home planet; the Heir Turnus Captol, likes to actively enforced a strict authoritarian rule, whereas Devora favors a more hands-off and peaceful approach.

Both the Emperor and the Heirs are charged with caring for the age old lusi, Gl'bgolyb, (regardless of what lusi raised them) known as "The Rift's Carbuncle", "Emissary to the Horrorterrors" and "Speaker of the Vast Glub", who compels the younger troll to challenge the older for control of the throne. In order to prevent this, Gl'bgolyb must be kept quiet by the Magenta blooded troll, as Gl'bgolyb's voice is capable of killing trolls in ascending strengths and numbers depending on how loud it is, with the lower castes susceptible to anything above a whisper, to the devastating Vast Glub which kills all trolls in the universe save for the Magenta bloods.

The Tortuerer Imperious is serving as Emperor of Alternia and focuses on off-planet conquering, while he leaves his first Heir Turnus to tend to Gl'bgolyb. Whichever Magenta troll is closest to Gl'bgolyb, it's allegiance will sway toward.

As a member of the top blood caste, the Torturer is given a much longer lifespan. He also has the ability to extend the lifespans of others, but it is unclear if this is related to his blood color or his status as a King of Time.

Devora, has Magenta blood, but he rejects the throne and the hemospectrum, as he would rather serve the race rather than rule over it with an iron fist.

Violet Blood is the second-highest color of blood in the hemospectrum and is the first of two that exclusively belongs to sea-dwelling trolls, which are noted for their ability to breathe underwater, fin-like protrusions from their neck, and collapsing and expanding bladder based aquatic vascular system (which is merely a fancy term for the heart).

Violet-blooded trolls tend to be more violent than the others seeing as they are high on the hemospectrum, and express an extreme hatred towards the land-dwelling nobility. They also tend to be affiliated with piracy and are considered a part of the aristocracy.

Known purplebloods are Lyinus Mousai, his ancestor The Overseer, his dancestor Cogito Mousai, Poserp Antone, his ancestor Pilferer Hornigold, and his dancestor Muller Antone. Pilferer Hornigold, Muller, and Poserp Antone show some sence of violence towards the land dwellers. Most Violet blooded trolls seek a matespritship with their Magenta blooded counterparts.

The Overseer and his descendants do not display the same violence towards land dwellers as the others, which is usually not the norm in the culture. However, this could be due to them hiding their blood color, and therefor trying to hide any biases they hold toward land dwellers.

Violetbloods are permitted to do just about anything on Alternia, and have very little restrictions in society, since they are considered royalty. They may publish anything in magazines that they want, whether it be harsh criticisms or what they had for lunch that day.

Purple Blood is the highest ranked blood possible for land-dwelling trolls, and members of this caste are referred to as the "highbloods." Because of their position on the hemospectrum, purple blooded trolls are more prone to extreme violence and unpredictability, and it was for this reason that most were tasked as the violent subjugglators under many Empresses/Emperors.

All the purple blooded trolls are adherents to an Alternian Juggalo-like cult that believes that "a band of rowdy and capricious minstrels will rise one day on a mythical paradise planet." Purple blooded trolls are granted psychic powers, which permits them to keep the lower blood castes in check.

Known purplebloods are Geogic Rustic, his ancestor The Decadent, The Foresaken, Pookie Thuvil, Caliyp Thuvil, The Deserted, Khepri Böregi, and helios Böregi. The Foresaken once served as a subjugglator, and it is many purple bloods dream in life to hold a position like that.

The Deserted has demonstrated the ability to psychically give mental actions to those he gazes at, being able to control what they do next. Khepri's psychic powers are similar to his ancestors, however his appear to be more of mental suggestions, being able to sway the persons next action in his favor. As of now Helios is yet to show his psychic abilities, possibly in part to his rejection of controlling others.

The Forsaken has a psychic empathetic lock on any person, being able to make them feel any emotion she wishes, or make they feel how she feels. She can also use this ability the opposite way, she is also able to feel how others feel with that link. Her decendednt Pookie is able to by hypnotic gaze make this link with another person and see how they feel about any given topic, making her an expert intimidator and lie detedctor. Her final decendednt Caliyp is able to psycically conjur up someones past memories, inorder to try and evoke emotions. the extent of how these powers will work is still unsure.

The Decadent's psychic powers allow him to force great pleasure onto anyone. The feeling of drowsiness and euphoria envelops them in the stimulating throes of a great high comparable to an empathogenic drug high or sexual climax. He is known to use this not only for keep lower bloods in check, but to torment people. Leaving them in a twitching, immobile, psychoactive state. He has stated his descendent, Geogic, has the same ability, however he refuses to use it unless it is for its intended purpose (while doped up, at least).

All of the purple blooded trolls are also highly violent and unpredictable, but it is only after Geogic and Pookie run out of their narcotic of choice (sopor slime, drugs, or alcohol) that their true purple blooded nature arises.

As it is a median color between the blues and the sea-dwelling purples, it is fitting that many live on the shoreline. All purple blooded trolls have aquatic lusii, but live on land. That would also mean it's common for purple bloods to live on the coast shore, to be close to their lusii as they would be out of reach otherwise. This caste is male dominated.

Indigo Blood is the second-highest tier of blood amongst the land-dwelling trolls. They are considered part of the nobility, and as such they have a traditional rivalry/mutual kismesissitude with the sea-dwelling trolls. They are prone to violence as well because of their location on the hemospectrum. As with cerulean blood, this blood type is commonly called "blue," but the color has been alternately referred to as "indigo" when used as ink or in a potion.

Khyyam Bedlam, her ancestor The Hecatomb, and her dancestor Pupill Bedlam are all indigo blooded trolls. Their enormous strength is unique to this caste, and is a blueblood trait.

Some jobs are ruffiannihilator, and archeradicator (an elite archer of the imperial forces ).

Indigobloods have a reputation of being snooty and stuck-up. It is likely that the entire caste cares immensely about the hemospectrum. This caste is male dominated.

Cerulean / Cobalt Blood is the first rung of nobility. It is suggested that cerulean blooded trolls are unlikely to develop psychic powers. Usually this blood color is simply referred to as "blue," which can cause confusion as indigo blood is also referred to, and appears to be, blue.

Rampio Agenis, his ancestor The Goodfelo both have cerulean blood.

This caste is male dominated, and is extremely unlikely to gain any psychic abilities.

Teal / Aqua Blood is considered a high class in Alternian society. As a chromatic median between the green and blue castes, teal blooded trolls are not quite considered nobility, but still outrank the middle-class green blooded castes. Trolls of this blood color typically take civil servant positions, such as that of a legislacerator. It is typical for lusii of this caste to be cholerbears and spleenfowls, both implied to be big enough to carry their trolls.

Mitéra Tarrae, and their ancestor The Maddonna all have teal blood. Many are legislacerator, the Alternian equivalent of a lawyer who also doubles as a bounty hunter.

They use their verbal prowess to affect others, rather than any sort of psychic ability.

Lime Blood was once a very common blood caste on Alternia, but was hunted to extinction by the others due to its members' possession of powerful abilities that threatened the authority. Sometimes referred to as "yellowgreens", considering the term "lime blood" offensive due to its historical connotations, the caste was historically oppressed.

The Eηηonnos, Pergio Astart, and Aladin Astart are all Lime variants. They are the only of this caste. This lighter shade fits in the color wheel between Phykhe's yellow and Coelum's green.

Jade Blood is rare among trolls, and trolls with this blood color are given a unique role in troll society. In the past, jade blooded auxiliatrices were tasked to tend to the Mother Grubs in the brooding caverns. On Beforus, they were a predominantly female caste and their duties also included caring for wigglers.

Wellnigh Raja, Pallas Deithe, Thebes Deithe, and Janete Isobel seem to be able to withstand the intense light given off the Alternian sun. It seems that many jadebloods tend to follow a goth thematic.

Many eventually turn into a rainbow drinkers (the Alternian equivalent of a vampire, who can withstand the planet's sun and radiates light) upon death. Being a rainbow drinker indeed directly relates to having jade blood. It is also stated that the caste must have developed these abilities after working in the dark birthing caverns, while others suggested that the ability could have been developed to scare predators away from young wigglers.

Olive Blood is considered the "middle class", and the color is referred to as ok but not great. Can simply just be called "green", but this may not be the specific term, as there are two other shades of green on the hemospectrum.

The Thesbian, and his descendent Coelim Hestod are both olive bloods.

Many Olive bloods are not known to have any sort of psychic power. This may indicate that somewhere in the green part of the hemospectrum, trolls start to be more likely to be born without psychic powers.

Yellow / Ochre / Gold Blood is the third-lowest blood color. They are also very likely to have psychic powers. "Gold" is the name used sometimes.

The Cannibal, and her decendent Phykhe Cyprot are both powerful psionics, with Phykhe and the Cannibal capable of using their mental powers to move massive objects at high speed.

Phykhe is capable of firing destructive blasts from her eyes, which is a typical power of this caste. It is implied that this specific set of powers is only common to mutants within the caste.

Phykhe and her ancestor are both gifted with a type of "clairvoyance", which alows them so see what others need, which makes them incredibly good at seduction and saying "just the right thing". When using this they can make virtually anyone fall for them, given the correct circumstances it can also be used to threaten someone.

In the older eras, psychically gifted yellow bloods were commonly enslaved as mages and helmsmen.

Bronze / Umber Blood is the second-lowest class of blood. Trolls of this caste have also been called fudgebloods. This was referred to as Bronze, however it can also be referred to as Umber; however, that is an old term.

The Strumpet, Satyre Faunus, Mattrona Lineal, Tagury Phaest, The Follower, Domiin Antqui, The Windfall, and Tychee Fortun possess this blood color. The psychic ability to commune with and command the various beasts of Alternia is quite common in this caste.

Burgundy Blood is the lowest blood caste in existence. It is sometimes referred to as the color "burgundy" . "Rust" is used to simultaneously refer to the castes of Bronze and Burgundy.

The Chimaera, Metail Thalas, Aeneas Sabine, and Martis Sabine all have burgundy blood. Burgundy bloods are notable for having the shortest lifespans - they generally live only a dozen sweeps or two, or roughly 30-60 human years. They are the most likely to have psychic powers. This is a double-edged sword, however, as they are also the most psychically susceptible.

Metail and his ancestor can use their own bodies like a voodoo doll, but only to such a point. Injuries that are too serious might be too severe to pass on.

Martis and his dancestor can create physic weapons to fight with, they are technically just physically projected blasts, that they give shape to (i.e. mace, gun, sword, axe, etc).

Some of these psychic powers allow them to manipulate the position and velocity of objects. It is suggested that that these telekinetic powers are common among the caste.

All rustbloods possesses the ability to communicate with the deceased. They could also possibly summon ghosts, commune with them and command them to do their bidding.
