Nico di Angelo

"Your death would be great for me."

- Nico di Angelo

Nico di Angelo is the son of Hades and the mortal Maria di Angelo and the full younger brother of Bianca di Angelo. He is 11 years old in The Titan's Curse, about 13-14 years old in the Son of Neptune, although he is actually more than 70 years old (revealed in The Titan's Curse) by the end of The Last Olympian, as he was born before World War II. In The Son of Neptune, he is shown to be his father's ambassador to Camp Jupiter.

History
Nico was born before World War II, so technically Hades never broke the oath he took to never have any half-blood children. They both lived in Washington DC. When Nico and Bianca were young, their mother died when Zeus struck the hotel they were staying at with lightning while trying to kill Nico and Bianca, who were protected by Hades. Both were brought to the Lotus Hotel by the Fury Alecto, who was disguised as a lawyer in order to protect them. Alecto was also instructed by Hades to bathe them in the River Lethe to wipe their memories. After their mother died, the Oracle showed up shortly after the destruction of the hotel and was cursed by an angry Hades to never have the Oracle 's soul rest and to be locked in that body, even after it died, until he and his children became accepted in Olympus. This resulted in her being the mummy of the Oracle at Camp Half-Blood until the end of the second Titan War.

After what they thought was a month in the Lotus Hotel and Casino, which was actually approximately 70 years, they were taken out by Alecto who was disguised as a different lawyer than that who carried them in. Hades did this because he wanted one of them to be the child in the prophecy and not the "idiot" son of Poseidon, referring to Percy.

The Titan's Curse
Nico first appears with his sister, in a military school called Westover Hall, in Bar Harbor, Maine. Bianca and Nico were almost kidnapped by a manticore named Dr. Thorn. Thalia, Grover, Percy, and Annabeth attempt to save them, but it is the Hunters of Artemis who come to the rescue. The siblings were sought out by Grover Underwood, who believed them to be two very powerful unknown half-bloods. Nico is about ten, and seems to be very interested in Mythomagic, a card game about Greek mythology, that bares somewhat of a resemblance to Yu-Gi-Oh or Pokemon. But when 12 year-old Bianca accepts Artemis' proposal to become a Hunter, Nico gets angry at her for abandoning him. Percy finds Nico eavesdropping on Bianca and Zoë, and Nico successfully convinces Percy to promise to keep his sister safe. He doesn't appear again until the end of the book, where Percy explains to him that Bianca died to save the others on the quest. He immediately turns on Percy, telling him he hates him, and reminding him of the promise he made to keep Bianca safe. Percy tries to comfort him, and Nico claims he can sense her soul being judged. When the last four Skeleton Warriors appear in the camp, Nico tells them to "Go away!" and they are swallowed by a fissure in the ground that Nico creates by accident. Nico is last seen running into the woods at night. Percy then realizes that Nico is a son of Hades after finding the god statue that Bianca told Percy to give Nico if she died. The statue represented Hades, Lord of the dead.

The Battle of the Labyrinth
Nico is first seen through the Iris message that Bianca sent to Percy. He has honed his powers as the son of Hades with help from the ghost of King Minos, who had been training him. He tried to summon Bianca's ghost many times, but failed. Frustrated, he seeks to make a deal with his father by trading "a soul for a soul." Percy thinks that Nico is after him, but Nico is after somebody else.

Nico decides to find the soul of someone who cheated death and trade it for Bianca's. Later, he meets Percy, Annabeth, Tyson, and Grover at the Triple G Ranch. He'd entered Triple G Ranch to discuss finding the soul he needed with Geryon. Angered, he threatens them, but is stopped by Geryon. He still blames Percy for Bianca's death, and tells him so. He is then tied up by Geryon to be sold to the Titan Army. When Percy offers a deal to Geryon to save him, Nico shouts that he does not want to be saved by Percy.

Percy still saves Nico, and convinces him to try and summon Bianca's spirit again. However, Bianca tells Nico not to be angry at Percy or hold grudges, because that is the fatal flaw of the children of Hades. She says to stop blaming Percy because it is really she that Nico is angry at for abandoning him. She also gives a warning about Kronos sensing Nico, and then she disappears.

He stays at the Triple G Ranch while the others leave. Nico is tricked by Minos into going back into the maze to save Percy, but is captured by two dracanae of Kronos'. In the battle at Daedalus' workshop, Nico opens a fissure in the ground, sending Minos back to the underworld. He tells Percy that only the dead accept him, and they only do so out of fear.

He escapes with Percy, Annabeth, and Rachel, who have to go back into the Labyrinth to find Grover and Tyson. Along the way, they see Kronos (in the form of Luke Castellan), and Nico, in a desperate attempt to save everyone, shows his true powers, conjuring a wall of black stone making it known to Kronos that he is a son of Hades.

When they found Grover and Tyson, they also found the long-lost god Pan, and Nico notices that he is the only one that Pan doesn't talk to.

During a battle in the labyrinth, Nico summons undead warriors to fight. The effort nearly kills him, and he collapsed on the ground at the end of the battle. Percy finds him and helps him by giving him nectar. He releases Daedalus' soul after that, who offers his soul for ransom, but Nico decides Bianca should stay where she is.

He feels out of place at Camp Half-Blood, and refuses to eat with the other demigods or join the singalong at the amphitheater. Nico summons Bianca's spirit one last time. He tells Percy that he will leave Camp Half-Blood because he feels that he doesn't belong there like his father doesn't belong on Olympus. Before he leaves, Percy gives him the small Hades statue that Bianca had given him before she died.

He appears again at the very end to Percy and offers a way to defeat Kronos, but is distracted by Percy's blue birthday cake (assuming he's probably never had a birthday party in his life), and Percy offers him some, and they both go inside, which leads into the next book.

The Demigod Files
Nico is one of the three demigods (along with Thalia and Percy, or all the known Greek children of the Big Three) whom are summoned by his step-mother Persephone to find the Sword of Hades. His knowledge of the Underworld and of its occupants within it help them complete their quest. He remains in the underworld afterward to discuss the oncoming war with his father. Before his friends leave, he reminds Percy of his idea to defeat the Titans (bathing in the River Styx).

The Last Olympian
Nico's theory to gain an edge over the Titans is to make Percy invincible by having him bathe in the River Styx, similar to the myth of Achilles. It is shown that after Bianca died, Hades feels he has no competent child, repeatedly mentioning that Bianca could do a better job at fulfilling their father's demands.

Nico is first seen in one of Percy's dreams where he is eavesdropping on a group of Titans. It is later confirmed that this was true. Percy sees him again while walking Mrs. O'Leary. Nico is with Juniper and Leneus, discussing Grover's disappearance. Nico, Percy, and Mrs. O'Leary then meet Mrs. Castellan on a disturbing visit by shadow-travel. Soon after, the three enter the Underworld, where Percy is trapped by Hades and rescued by Nico. Nico helps Percy bathe in the River Styx.

It is also revealed that the lawyer who removed the children from the Lotus Hotel and Casino was the lead Fury, Alecto, in disguise. Nico attempts to summon the ghost of his mother, but Bianca appears and tells him not to. He sees the scene of their mother's death in which Zeus blasted the building she, Hades, and the children were in to pieces. Hades, who realized what was happening too late, only managed to save the children Nico and Bianca. He then tells Alecto to wipe the memories of the children, including their mother's death.

By viewing this scene, Nico finds out who his mother is and is able to convince his father to help the campers in battle. He fights in the Battle of Manhattan with his father, the Lord of the Underworld. Together, they summon wave after wave of soldiers of the undead against Kronos' forces. Nico is last seen ordering undead workers to build the Hades cabin, made up of solid obsidian walls with a skull over the door. Torches blaze with burning green fire that will never extinguish.

Between Series
As stated in The Son of Neptune, in the September following The Battle of Manhattan, Nico rescued the spirit of his half-sister Hazel Levesque from the Fields of Asphodel while looking for Bianca, who has made it to the Elysium and can not go back to the mortal world. With Thanatos captured, the dead were returning to the world anyway, Nico felt Hazel deserved another chance at being a hero (Gaea said that he had selfish reasons for doing this, but it is unknown if he had any or for what selfish reasons did he do it for). As stated by Dakota, Nico took Hazel directly to Camp Jupiter and asked Reyna to take her in.

The Lost Hero
Nico is mentioned in The Lost Hero to be searching for Percy along with Tyson, Grover and the Hunters of Artemis, but otherwise doesn't appear. It's to be assumed that he doesn't stay at Camp Half-Blood much, as Annabeth said he "sometimes" shows up.

The Son of Neptune
Nico meets Percy at the Roman camp, where he is visiting his half-sister, Hazel Levesque. When they meet Nico is shocked and easily regains control over it. He is posing as a son of Pluto and as an ambassador for Pluto. He later tells Hazel, after Percy leaves with Frank, that he knows Percy, but Percy must regain his memories by himself. It is not clear whether he gained this knowledge from his friends at Camp Half-Blood, who had long since figured out what had happened to Percy's opposite number, Jason Grace, or if Hades or another god told Nico directly.

Later in the book, Nico sets off to see if he can locate the Doors of Death from inside the Underworld. It is later known by the enemy, who tells this to Hazel and Frank and Percy found out later on, that Nico has been captured by forces loyal to Gaea and is somewhere in Rome.

Personality
In The Titan's Curse, Nico is ten years old and enjoys playing with his Mythomagic Cards that none of the others truly seem to understand. He is totally clueless and very inquisitive: he begins annoying Percy with his ceaseless questions, especially when he asks questions about Annabeth, which eventually makes Percy consider "stuffing him in a meat flavored sack and throwing him to the wolves." He is excited about finding out that he is a Demigod (immediate response: "Cool!"), and compares monsters to Mythomagic creatures. He feels abandoned when his sister, Bianca - who practically acts as his parent, becomes a Hunter of Artemis. When she goes on a quest, Nico makes Percy promise to protect her. After her death, he develops a long-lasting grudge toward Percy for letting her die. Once he realizes that he is a son of Hades, he casts away his childhood interests and runs off on his own.

He becomes more a dark and solitary character during The Battle of the Labyrinth, saying that "only the dead respect me... and only out of fear." He believes that he will never be accepted by the living, and does not belong at Camp Half-Blood, but forgives Percy after Bianca's ghost tells him that it wasn't his fault that she died. He also accepts the small figurine of Hades that Bianca wanted him to have.

In the fifth book, The Last Olympian, he instructs Percy on how to bathe in the River Styx. He is quite sincere in wanting to help him with the prophecy and the war.

Nico is later proven wrong in the belief he will not be accepted by the living. After the war is over, all the campers of Camp Half-Blood welcome Nico cheerfully: as Percy puts it,"If you come into battle with a hundred undead soldiers to save the day, you're everyone's friend."

Fatal Flaw
Nico di Angelo's fatal flaw is holding grudges, as Bianca's ghost tells him - which, in his case, can lead to not wanting help or asking to be saved in deadly situations because he doesn't like someone. Examples are his not wanting to be helped by Percy, even when Geryon was going to sell him to the Titans and not wanting to go back in the Labyrinth with them. Bianca shares this with him, as she also had the same fatal flaw in life, although this didn't lead to her death. Bianca also says that holding grudges is the fatal flaw of Hades' demigod children. In the fifth book, Nico tells his father that he (Hades) is holding a grudge that could end up killing the Olympians and the campers.

Appearance
He is said to have shaggy black hair that always looks like he just got out of bed, olive skin that has paled over the course of The Battle of the Labyrinth, dark brown eyes, and wears mostly black, (a pair of ripped black jeans, black shirt-sometimes with skull print-and a chain for a belt) sort of Gothic clothing. By the end of The Battle of the Labyrinth, he has a silver skull ring which is said to belong to his father, stated by Hazel, and he has a Stygian Iron sword always by his side. When he shakes hands with Percy at the end of the Battle of Labyrinth, Percy says that Nico's hand is "cold as ice." He is also mentioned on several occasions wearing an aviator's jacket, most likely because he had distant relatives in WWII. Hazel also points out how his fingers are ghostly white, like their father. At Camp Jupiter, Nico is seen wearing a black toga when Percy goes to talk to the praetors (the reason being that togas are only worn on special occasions, like meetings).

Abilities

 * ADHD: Like all demigods, Nico possesses inborn supernatural battle reflexes and senses that he uses to analyze the fighting style of his opponent.
 * Dyslexia: Nico's brain is "hard-wired" for divine Ancient Greek instead of mortal languages.

Demigod Powers
As a son of Hades, Nico is himself an underworld deity. He is considerably more trained in using his powers than other children of the Big Three, such as Thalia and Percy. He has Necromancy, Umbrakinesis, and Geokinesis. Before she met Percy Jackson, Hazel considered him the most powerful demigod she knew. His confirmed powers include:
 * Geokinesis: Control of the earth, levitating rocks and making them deadly, black, and extremely sharp, the ability to create earth tremors, and open fissures in the earth. Can cause earth tremors so powerful, they can shatter the pillars of a mountain fortress.
 * Can control the black walls of the Underworld
 * Can create fissures that swallows up creatures and traps them in the Underworld.
 * Necromancy :The power to control the dead.
 * Summon the dead.
 * Putting the dead (and possibly others) to sleep.
 * Communicating with the dead.
 * Divine authority and control over the Furies and the dead.
 * Banishing the dead.
 * Releasing people who should have died (i.e. Daedalus).
 * Destroying Skeleton Warriors.
 * Physically manipulating ghosts, such as taking hold of them by hand or forcing them to be silent with a gesture.
 * Death Sense: can sense death and understand knowledge of things related to death.
 * Knowing when a close person dies, which comes as a ringing in his ears.
 * Can sense when an immortal is fading, like Pan.
 * Can sense someones life aura, he could sense it when Rachel Elizabeth Dare's life aura faded "I could see you dying."
 * Deep knowledge of the Underworld.
 * Knows when a person's life is being judged in the Underworld.
 * Umbrakinesis : Control over darkness and shadow for various uses such as solidifying it for attacks and to hide in it.
 * Shadow travel: Umbragous teleportation.
 * Dark Pyrokinesis: can use of fire from the river Phlegethon (river of fire), like his father (although to a limit).
 * Induced Fear: Radiates fear and death like his father, Hades, but to a much lesser degree.

Items

 * A Stygian iron sword. It is three feet long, and in The Last Olympian is described as being "black as a nightmare." It helps Nico to channel his power to control and summon the dead, and it can also drain souls to give the sword more power. Only Hades and his children can use Stygian Iron for their weapons.
 * He is seen wearing black armor in The Last Olympian with a skull shaped visor.
 * A skull ring shown in the last two books and in Son of Neptune.
 * Mythomagic figurines and cards. He throws them in a fire in anger in The Battle of the Labyrinth.
 * In The Battle of the Labyrinth he had a pair of Daedalus' wings, but after he used them, he threw it away in a trash can.
 * A red travel rose, given to him by Persephone, that he didn't use in The Sword of Hades.
 * A Hades Mythomagic figurine, given to him by Percy, from Bianca.

Etymology

 * The name Nico is the diminutive form of Nicolò, the Italian form of the Greek Nikolaos (Nicholas), meaning "victory of the people." It is most likely intended to evoke the prefix necro-, meaning dead. His surname is Italian for "of the angels," alluding to his role as the Lord of the Dead's son.

Trivia

 * The line "With great power. . .comes great need to take a nap." is a near obvious reference to one of Spider-Man's most famous line: "With great power, comes great responsibility", albeit a bit altered for comedic effect and to indicate that Nico's powers tire him greatly, prompting him to take naps every now and again to regain his strength, as he did at that moment in The Last Olympian.
 * Nico's physical description (pale skin, dark hair, brown eyes, black clothes, and an aura of death) also fits Rick Riordan's description of Anubis, the Egyptian god of funerals, in the Kane Chronicles series.
 * The first time he met Mr D., he called him "The wine dude", which irritated the god, but he forgot about it soon after.
 * Nico was turned into a dandelion for a short period of time by Persephone during a "family spat." This was never seen directly in the books, but is talked about by Nico and Persephone in The Demigod Files.
 * Nico has been to a New Orleans graveyard, it is unknown why he went though. Interestingly, this is one of the favorite hangouts of another death god (a.k.a. Anubis, the Egyptian god of funerals). It was also the place that his half-sister Hazel Levesque lived just before her death.
 * Nico blushes when a female touches him. Either when they do it show affection or appreciation (Shown when Juniper, Grover's girlfriend, touches his arm in The Last Olympian).
 * Even though Nico and Jason Grace have never met before (in the books at least - Jason refers to Hazel in the end of The Lost Hero so may have met him when she was brought to camp), they do share some similarities:
 * They are children of the Big Three.
 * They both have older sisters
 * Their elder sisters have been Hunters of Artemis.
 * They have both been to Camp Half blood and Camp Jupiter
 * They have godly stepmothers (Persephone,Juno).
 * Both have lost their memory. Nico's because of being dipped in the River Lethe and Jason's was removed by Hera/Juno (Though, Jason's is temporary)
 * Nico has the ability to annoy Percy Jackson, his cousin, quite easily. He does this in The Titan's Curse by asking Percy several questions ("At this point, I was ready to stick the kid in a meat-flavored sack and throw him to the wolves."), in The Last Olympian by leading Percy to his almost demise, and in The Son of Neptune by not telling him he previously knew him ("Percy was anxious to find Nico for his own reasons- to wring the kid's neck for having pretended he didn't know Percy when he first came to camp.").
 * Hazel Levesque and Nico's mother's have very similar names: Marie Levesque and Maria di Angelo.
 * Nico's birthday is January 28,1942
