Nico di Angelo

Nico is chronologically over eighty years old as a result of his prolonged stay in the Lotus Casino in Las Vegas, an enchanted hotel where one does not age and time does not pass at its normal pace. He was ten years old in The Titan's Curse. He and his sister, Bianca di Angelo, were placed in the Lotus Casino sometime around World War II. They were eventually taken out by a "lawyer" (The Fury, Alecto) when Hades commanded. He also found his half-sister Hazel Levesque in the Underworld and took her back to Camp Jupiter as she was a child of Pluto.In The Titan's Curse, Nico is a composed kid who loves a trading card game called Mythomagic. However, since his sister's death in The Titan's Curse at the hands of a defective Talos, he has a hateful resentment toward Percy. He later thinks Mythomagic is a stupid game, and burns all his cards in a fire. He becomes more sullen and solitary, saying that "only the dead respect him...and only out of fear". He believes that he will never be accepted with the living, but forgives Percy after Bianca tells him that it wasn't Percy's fault that she died. He also accepts the small figurine of Hades that Bianca wanted him to have before she died in The Titan's Curse. In the fifth book, he brings Percy to his father to get information that proves to be the least his father can give, and his father ends up putting Percy in a dungeon. However, Nico rescues Percy from the dungeon and takes him to the River Styx where Percy becomes almost invincible. In the end of The Last Olympian, Nico convinces his father, Hades, to help the other gods fight in the war against the Lord of Time, Kronos, and his army, and plays a major role in the victory. The relationship between Percy and Nico becomes close for they both might have been the child of the Great Prophecy.

His skin is described as “a sickly greenish-white, like the color of tree sap."His hair is always overgrown and shaggy. He always dresses in all black and wears skulls also mentioned on several occasions to be wearing an aviator's jacket. By the end of The Battle of the Labyrinth, he also wears a skull ring, a gift from his deceased sister Bianca. His favorite color is actually green, because it reminds him of Bianca. He wears black because it’s much harder to shadow travel in bright colors.There is a time that he tried to wear blues and greens and reds as much as possible. But if he wanted to get out of the Underworld, he had to wear black. He has this Stygian Sword as his weapon.

he is the demigod son of Hades and mortal Maria di Angelo. As such, Nico has extraordinary powers of necromancy, the power to command the dead and the power to summon the dead. He is a son of one of the "Big Three" Greek gods, the other two being Hades' brothers Poseidon and Zeus.Hades (father) Maria Di Angelo (mother, deceased) Bianca di Angelo (sister, deceased) Hazel Levesque (half-sister)

In The House of Hades, Nico is forced by Cupid to reveal that he had had a crush on Percy Jackson. This reveals that he is gay. In The Blood of Olympus, he later says that he does not feel that way anymore about Percy, and that he had been young and impressionable at the time, (by saying Percy is "not his type") and is seen to be potentially crushing on Will Solace (head counselor of the Apollo cabin).

In The Trials of Apollo: The Hidden Oracle, Nico is in a romantic relationship with Will and receives the enthusiastic support of Apollo (Will's father) for their relationship

Nico's sword is made of Stygian Iron, which will kill monsters, and, unlike the other metals of Celestial Bronze and Imperial Gold, is capable of harming mortals. The metal, when being forged, is cooled in the River Styx, making it indestructible. It is implied that only beings of the Underworld, such as Hades and his children, are able to use a Stygian iron weapon.The sword helps him channel his power to control and summon the dead, along with draining an enemy's soul to reinforce his sword's power. He can also use it to create fissures in the ground, trapping anyone unlucky in the underworld. This is like what he did to king Minos. Nico being an incredibly powerful demigod; he has many powers and is aware that “With great power... comes a great need to take a nap," as he says after putting to sleep all of the skeleton guards in the Palace of Hades during his and Percy's escape from imprisonment during the Last Olympian.Nico has ADHD like other half-bloods, which allows him a heightened sense of awareness in combat.As with most other half-bloods, Nico is dyslexic because his brain has been "hard-wired" for Ancient Greek. However, not all are dyslexic or have ADHD, such as Frank Zhang. Nico, being a son of Hades, is one of the most powerful demigods alive. He can slay monsters with little effort.Nico can open up grounds and bury creatures alive. Nico has dominion over the dead, giving him the title ‘Ghost King’.Nico can summon and communicate with the dead. He can sense when a mortal or half-blood has died through a buzzing in his earsNico is shown to be able to release a soul into the underworld, as he did with Daedalus.Nico can shadow-travel, a form of travel that uses shadows that enables him to teleport to different places although this ability tires him after a long period of time and he can begin to ‘fade’.Nico can bend shadows around him to conceal himself.He can control dark energy like Hades but to a much weaker extent.

He can shadow travel others by force if he has direct skin-to-skin contact with them. He can cause immensely powerful tremors. He can control the dark obsidian souls of the underworld. He can travel through dreams He can see others memories He can force ghosts into silence by putting a finger to his lips. He can turn others into ghosts and send them into the underworld as he did with Bryce Lawrence. He can release dark waves from his body, these waves were so powerful that they almost knocked out Jason as collateral damage.

Nico is jaded, yes, and often closed-off and sometimes stand-offish and defensive but he is not “cold”. He cares SO SO SO MUCH about EVERYONE. He loves and cares with his entire heart constantly and that is a core part of his character. He doesn’t often make public shows of his affection but he takes care to be kind when it matters and doesn’t hide that he does care (usually, the only exception really being him being in the closet, but even then he only hid his crush specifically and not the fact that Percy is important to him). He fine with hugging his friends in front of a crowd and will sit with strangers at a campfire just so they’re not alone. I mean, heck, he’s an extrovert! We know this! He actively seeks out people and gets lonely very quickly and easily! If he can’t talk to living people he will chat with the dead! That’s how much he thrives on being social!terests and runs off on his own.

In The Battle of the Labyrinth, Nico becomes grim and solitary, and considerably more powerful. He says, "only the dead respect me... and only out of fear." His attitude may have changed both because of Bianca's death and Minos' manipulations. He believes that he will never be accepted by the living or Camp Half-Blood, much like how his father Hades feels out of place on Olympus. Nico is wanted revenge for Bianca's death, which he blamed Percy for. However, Nico 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.

He is so naive and gullible that he believes that Minos was actually helping him resurrect Bianca.
