Fair Snow-White: Zagreus (Earth-0)

"Hi there! No need for formalities, I'm Zagreus. Just heading out on some official business! Surveying the magma situation firsthand. Don't mean to be rude, though I'm in a bit of a rush."

- Zagreus to the wraiths in the underworld.

Zagreus, Prince of the Underworld, is the biological son of Poseidon and Kirke, and the adoptive son of Hades and Persephone.

Early life
Zagreus was born before 585 BC. Prior to his birth, Circe seduced Poseidon and became pregnant with his son. Unfortunately, she did not realize this until after she was banished to Tartarus by Hippolyta, for transforming innocent people into animals. After several months in the Underworld, Circe gave birth to a stillborn baby she intended to name Phaunos; as the Underworld was a place of death and decay, this ultimately led to Circe's child being born lifeless. Hades himself took her stillborn baby and had her taken back to Tartarus. Eventually, the baby was brought back to life via Hades' powers in an extremely lengthy process after Persephone begged Nyx to make a deal with her daughters, the Fates. Hades and the overjoyed Persephone then decided to adopt this child as their own, due to the Fates having decreed that Hades would never sire an heir. Naming the child Zagreus and neglecting to reveal his true parentage, Persephone and Hades adored their new child and spoiled him with every luxury they could afford. In his youth, Zagreus questioned where his mother disappeared to several months out of the year and once caught a glimpse of the surface world when ahe departed. This left Zagreus bewildered at the surface and he hoped that one day his mother would take him with her.

As time went on, Persephone and Hades chose to cycle Zagreus between the House of Hades and the realm of Elysium as Persephone disliked spending time with Hades. While with Hades, Zagerus was strictly disciplined and had Achilles as a tutor, whereas Persephone kept Zagreus mostly secluded in a tower in the Elysian Fields.

Escaping Hades
Eventually, Zagerus begged his mother to take him with her, but she refused, wanting to keep him for herself. Seeking to escape the Underworld, Zagerus used all the skills at his disposal and after "sirening" Hermes to take him to the surface, began to explore Greece.

At one point, Zagreus and Dionysus collaborated together in pranking Orpheus, leading the musician to believe that the two are the same person.

Personality
Zagreus is the rebellious adopted son of Hades and Persephone. He is largely defined by his persistence, good humor and wit, and his kindness. Having spent most of his immortal life bearing the brunt of his father Hades' repressed frustration and rage, he grew up feeling distant and out of place from the other denizens of the underworld, partially due to his failing to meet the heavy expectations of his father, and partially his apparent inability to contribute to the running of the Underworld. When he discovers the truth of his parentage, he decides to attempt to escape the realm of the dead to seek out his long-lost mother, Circe. Despite all the trials and many deaths he faces, he never wavers in pursing his goal, never showing any sign of doubt in his efforts, even in the face of his father's wrath, nor when his own mother at one point tells him not to seek her out anymore.

Zagreus is often shown to be humble, good-humored, and often sarcastic and self-deprecating. His jovial, if somewhat-insubordinate nature allows him to easily befriend the many people he encounters, treating people of lower status as his equals, although he is respectful of his elders (aside from his father), especially his fellow gods. He is sometimes shown to be somewhat blasé, which has led him to offend the people around him or act without thinking of the consequences. However, he often reflects on this and is quick to apologize when he oversteps. He has a mischievous side, and is fond of pranking others.

He is fiercely protective of his friends and loved ones, and goes out of his way to defend them with little regard toward status or societal expectations. He often leverages his own influence to improve the lives of others.

Due to his sheltered upbringing, Zagreus is often shown to be ignorant of the world outside of the Underworld, relying on others to relay information about the outside world.

Physical Appearance
Zagreus is somewhat small for a god, considerably smaller than Hades and a head shorter than Persephone. He is presumably of reasonable height for a mortal as he tells the Minotaur he is the same height as Theseus. His eyes are a medium brown color. His hair is jet black, like Hades. His skin is quite pale, and he is physically strong and muscular. Having an effeminate appearance, Zagreus wears a blood-red off the shoulder toga that ends above his knees and no shoes. Physiologically, Zagreus is eighteen years old.

Powers

 * Immortality: In the Underworld, Zagreus was ageless and had a potentially limitless lifespan. However, due to the circumstances of his resurrection, Zagreus is bound to the Underworld and should he leave the confines of Hades, his body with rapidly deteriorate and his spirit will be forcibly drawn back there. Due to Hades' deal, Zagreus can preserve his immortality and secure his footing on Earth by feasting on the flesh and feeding on the life force of others; how long he can go without feeding is unrevealed. He preferred to feed on evildoers. After he feeds on his victim's life force, their spirit is cast down into his adoptive father's Hell realm. Even if he dies, his spirit is sent to his adoptive father's Hell, and should Hades send his spirit back into his body, he can be resurrected under various circumstances.
 * Accelerated Healing: Zagreus stated that when he has eaten, he can withstand virtually any injury without pain, healing near instantaneously.
 * Superhuman Strength: Zagreus possessed superhuman strength, the limits of which are still unknown.
 * Magic: Zagreus inherited magical abilities from his birth mother, powerful enough to construct a shield to repel and stun Zeus. He was capable of casting magical spells, but the limits of his ability in this area are unknown. He was able to manifest his powers in assorted forms, including, but not limited to:
 * Micro-Cellular Manipulation: Zagreus can use magic or magical energy to levitate matter and bluntly manipulate it. The limits of his quasi-telekinetic abilities are unknown, but he has been observed lifting about 50 tons with some strain.
 * Neuro-Electric Sensitivity: Zagerus can enter into the minds of others to read their thoughts and access their memories. He initially used his voice as a focus for his psychic powers, but this was eventually refined into singing. He can strengthen this by making tactical contact, allowing him to search the deepest recesses of a person's subconscious. He is capable of telepathic communication even from a great distance as Seraphim was contacted by Zagerus from within the House of Hades while he was flying at an unknown distance away.
 * Mind Control: Zagerus can take over the minds of his victims, even to the point of shutting them down. The victims are conscious of this interaction as it creates a psychic rapport between Zagerus and his servant. This allows him to maintain a constant presence from within such that servants straying too far from Zagerus will be struck with psychic pain and suffer hemorrhages until they return to him. By using his "siren song," mind control can be used en masse and has even be used via cellphone service to access and reestablish the psychic connection. However, certain strong-willed or mentally anomalous individuals can resist his influence; in certain situations, this can causes increasing intracranial pressure in his resisting victim. He can also use his mind control to emotionally soothe people.
 * Memory Manipulation: Zagerus possess the ability to manipulate and change the memories of the victims under his control. Zagerus has shown the ability to erase Hermes' memory, altering his subconscious enough that he forgot on his own the time they first met.
 * Psychic Pain Infliction: Zagerus is able to induce extreme amount of pain through his enhanced telepathic powers. He was able use this technique on Heron, which was strong enough to manifest physical symptoms, such as coughing up blood and nose bleeds, while being separated great distances and maintaining normal appearances.
 * Psychic Illusions: Derived from his mind control, Zagerus can create psychic illusions, forcing his victims to see whatever he wants.
 * Voice Manipulation: Modeling himself after his cousins the sirens, Zagreus is able to mystically manipulate his voice to lure his victims. Zagreus has shown to use his voice to captivate others through singing and mimic the voices of others like Hades and Electra. His control was so fine that he was able to generate sound waves to match the resonant frequency of glass in order to break it.
 * Limited Chlorokinesis: A skill taught by his adoptive mother, Zagerus can affect the growth of fauna to an unknown degree.
 * 'Thermokinesis:" Zagreus has been shown to generate extreme temperatures to the point of combustion and freezing. However he has yet to control the fire and ice he generates.
 * Necromancy: Being inducted into the House of Hades, Zagreus had control over the dead, as well as many monsters native to Hades' realm, such as the Furies. Using magic, Zagreus can physically manipulate ghosts, such as taking hold of them by hand or forcing them to be silent with a gesture.
 * Levitation: Zagreus could levitate himself off the ground, but he apparently could not fly.
 * Allspeak: Due to the Allspeak (also called All-Tongue), Zagreus can communicate in all languages, Earth's dialects, and various alien languages.
 * Claws: Zagreus possessed sharp claws and could use them to inflict fatal wounds onto humans; his claws have only manifested when severely deprived of food or when his power had been siphoned. It is unknown if he can manifest them willingly.
 * Aquatic Respiration: Due to his birth father being the God of the Sea, Zagreus appeared to have some form of underwater adaptation. Zagreus spent many months underwater, suggesting that he is able to breathe underwater.

Abilities

 * Musical Talent: Zagreus played the harp and, regardless of his supernatural ability, was a trained vocalist as well, having been formally taught how to sing by the sirens his mother had befriended.
 * Expert hand-to-hand combatant: Zagreus has been trained by Achilles himself; in combat, he has bested Hades at least once.

Equipment

 * Zagreus' Sword: A Stygian Iron sword. It is three feet long, and is described as being "black as a nightmare." It helps Zagreus to channel his power to control and summon the dead, and it can also drain souls to give the sword more power.

Weaknesses

 * Hades: As the one who originally resurrected Zagreus and continued to do so, Hades could choose not to revive him and kill him with his own hellfire. His speed of recovery from an otherwise fatal attack was also dependent on Hades, as Zagreus' revival was delayed once as Hades held a conversation with him, prior to his soul being sent back to his body.
 * Hades' Bident: A long weapon that belonged to Hades, the Greek god of the underworld. The bident also acted as a tuning fork that operates at an unknown frequency that is capable of disrupting supernatural energy.
 * Hunger: Zagreus fed on the flesh of others which he require in order to maintain their youth and strength. Sirens also appear to require much more sustenance than vampires to be able to restore themselves if they haven't fed in centuries. Abstaining from such causes them to deteriorate to some degree, as seen with Sybil's hands after being released from the vault. Sybil also claimed that her eyeballs had rotted away over time whereas Damon mentioned that Sybil's face rotted off.
 * Magic: Zagreus was susceptible to the powers of magic, seeing as priestesses of Hekate were able to imprison him with various spells. It has been confirmed that a magic user could siphon the magic from Zagreus.
 * Moly: Zagreus shared his birth mother's vulnerability to the herb moly.
