Demigods(Half-Bloods)

Demigods, also known as Half-Bloods, are a hybrid species of human-like beings. All demigods are the offspring of a god and a mortal. All demigods wield Powers connected to the domain of their divine parent, and these abilities grow stronger with age. In general, they are a species of sub-gods who willingly assist their god parent and/or the gods themselves. Many have become great heroes, kings, lords, dictators, etc.

While most Demigods are created much like regular humans, children of Athena are born from their mother's thoughts merging with their father's. The other gods are likely able to do similar things, however no known examples of similar births are known.

They are escorted to Camp Half-Blood where they are placed into one of the Cabins, each honoring a different Olympian.

Most demigods wait forever to be claimed. Children of Athena are claimed at birth, while others have to demonstrate some form of their parents' trait to be noticed, either through cunning, powers, skills like archery, or even beauty. Otherwise, they are placed in Hermes' cabin, and since he is patron to travelers, anyone is welcomed there, including children of minor gods who aren't important enough to have a cabin. After the Second Olympian War, Percy Jackson had made all of the gods to recognize all of their children at the age of thirteen, and that each god and goddess (including the minor gods and godessess) gets a cabin at Camp Half-Blood.

Few demigods have siblings because the god parents cannot stay around long enough with their mortal consorts (with the exception of twins). Some examples of demigod siblings in the series, however, include Nico and Bianca di Angelo, Connor and Travis Stoll, and Jason and Thalia Grace (who have the same father, but in different aspects). Annabeth explained that Hades must've loved Maria di Angelo (Bianca and Nico's mother) a lot if he went back to her and had another child with her. Connor and Travis look very much alike, but aren't twins, so Hermes must've stayed with their mother after the first of the siblings, Travis, was born. Jason was born seven years after Thalia, when his father, Jupiter, revisted Ms. Grace, the mother of Thalia. Thalia was born in the lineage of Greece, however, as her father is Zeus.

Demigods often go on quests given to them by the Oracle of Delphi.

Appearance
Demigods are indistinguishable from humans. Because gods don't have DNA, they don't have any inhuman traits. They do not have a divine form, however they do inherit some traits from their god parent's divine form, for example, Percy inherited Poseidon's black hair and sea-green eyes and brooding look, Annabeth inherited Athena's gray eyes, Thalia and Jason (from The Lost Hero) inherited Zeus' electric blue eyes, Nico and Bianca inherited Hades' black hair, dark eyes and olive-like skin, children of Aphrodite inherit her beauty and appeal, children of Hermes inherit his elfish facial features. Children of Hephaestus, such as Leo, Jake, Harley, Nyssa and Charles inherit his skills with mechanics, calloused hands (from working in the forges all day long) and sometimes fire power (As in Leo's case).

Traits
The ichor in a demigod's blood stream gives them a distinct scent that all monsters can smell. There are ways to hide or mask the scent, but if a demigod realizes what he/she truly is, their scent will reach its peak. The scent of children of the Big Three is much more potent than that of lesser demigods. There are only four known children of the big three: Percy(Son of Posiedon), Thalia (Daughter of Zeus),Nico(Son of Hades)and Jason,(Son of Jupiter,Zeus' roman form).

Roman Demigods
Roman Demigods, such as Jason Grace, are a unique subset of demigods who train at the Roman Camp Half-Blood, which is located near San Fransisco. They are born when a god conceives a child with a mortal while in their Roman aspect. They naturally speak and read Latin, as opposed to Ancient Greek like other demigods, and are trained in the style of the Roman legions instead of Greek warfare. Like the Greek demigods, they are unaware of the existence of their counterparts at the Greek Camp Half-Blood in Long Island. This is due to conflict between the two groups back in the American Civil War, after which the gods manipulated the Mist as tightly as possible to stop the two groups from ever meeting each other again, although there have been some close calls. The head of their camp is an immortal she-wolf, Lupa, who originally cared for Romulus and Remus, the demigod founders of Rome. Little is known about her, the Roman Camp Half-Blood, or these demigods at this point.

Titan Counterparts
Although there is no mention of them in the series, it is implied that Titans, like the gods, can have children with mortals, although since they are much more inhumane than the gods it is unlikely that this would ever happen. It is possible that, if there were demititans, they would have powers related to the powers of their parents. For example, children of Kronos may have had the ability to control time.

Abilities
Demigods have ADHD, which hardwires them for battle, and dyslexia, which they have because their brains are hardwired for Ancient Greek(or Latin). Demigods are the only mortal beings who can (partially) see a god's Divine Form without being destroyed because of the ichor in their blood keeping them alive(barely). Demigods inherit some control over their divine parent's domain, such as Percy's ability to manipulate water or Leo's way with technology and tools. Some demigods also show some control of magic, like when the Apollo cabin cursed the Ares cabin to speak in rhymes, or when they summon monsters (though Luke is the only character shown doing it). Demigods also have a wide variety of other abilities that they all share but these ability varies depending on godly parent, including superhuman strength, speed, superhuman senses, agility,above-average healing-factor, durability, endurance, etc.

The Lost Hero mentions that the gods have influence over certain special powers that their children can receive, such as Hepheastus with his children's fire power (such as Leo Valdez), and Aphrodite with Charmspeak (such as Drew and Piper McLean).

Etymology
Most demigods' last names seem to relate to their Olympian parent:
 * Silena Beauregard, daughter of Aphrodite - Beauregard is French. It literally means "good looking".
 * Lee Fletcher, son of Apollo - A fletcher is someone who makes archery arrows.
 * Micheal Yew, son of Apollo - Yew is a favorable choice of wood to use for longbows.
 * Nico di Angelo, son of Hades - Nico is most likely deprived from the prefix Necro, to mean "dead". Di Angelo means "of angels".
 * Will Solace, son of Apollo - Though Solace really means "to comfort in distress", just as Will comforted and healed Annabeth when she was injured, Solace could also be a play on the word "Solar".
 * Thalia Grace, daughter of Zeus - The name of one of the three Graces (and nine Muses) is Thalia. She too, was a daughter of Zeus. The Muse Thalia sired the Corybantes, with Apollo. This Thalia was also attracted to Apollo.
 * Pollux & Castor, twin sons of Dionysus - They share the same names as the twins of the Gemini.
 * Jake Mason, son of Hephaestus - Mason means "one who works with stone".
 * Clarisse La Rue, daughter of Ares - La Rue is french, and means "Street". Which doesn't entirely relate to anything about Ares. However, rue is to regret, as Clarisse inflicts regret to all who face her in battle.
 * Travis and Connor Stoll, sons of Hermes - Their name is a homonym for stole, as Hermes is the god of thieves, which was brought up in the Sea of Monsters.
 * Katie Gardner, daughter of Demeter - Demeter is the goddess of the harvest and her last name refers to one who gardens or works with plants.
 * Miranda Gardiner, daughter of Demeter - Demeter is the goddess of the harvest and her last name refers to one who gardens or works with plants.
 * Piper McLean, daughter of Aphrodite-Piper was named "Piper" because of her high vocal cords because she can charmspeak.
