Bianca di Angelo

"You must listen to me. Holding grudges is dangerous for a child of Hades. It is our fatal flaw. You have to forgive. You have to promise me this."

- Bianca di Angelo

Bianca di Angelo is the demigod daughter of Hades and the mortal Maria di Angelo. She is the older full sister of Nico di Angelo. She became a Hunter of Artemis in The Titan's Curse after being saved along with Percy, Grover, Thalia, and her little brother Nico by the hunters.

History
Not much is known about Bianca's past. She and Nico were born before World War II, so Hades never broke the oath he took after the war to never have any half-blood children again.

Bianca and Nico both lived in Washington, D.C. at some point. When Bianca and Nico were very little, their mother, Maria di Angelo, died when Zeus struck the hotel they were staying in with lightning while trying to kill Nico and Bianca. The Oracle of Delphi showing up shortly after the destruction of the hotel, was cursed by Hades to never have her soul rest, and to stay in her body until it rots (and longer). He cursed her because she kept telling him that he should have given Bianca and Nico to Zeus as she knew their future.

Shortly afterward, both were brought to the Lotus Hotel by the Fury Alecto who was disguised as a lawyer. Hades had to erase their memories in the river Lethe, so they wouldn't remember anything about their previous life.

After what felt like a month in the Lotus Hotel, which was actually about 70 years, they were taken out by the same Fury (Alecto). Hades wanted them because he wanted one of them to be the child in the prophecy.

The Titan's Curse
Bianca is first introduced in The Titan's Curse, as a half-blood of unknown parentage (but it was realized after they figured out Nico's parent). After being rescued from the manticore by Percy Jackson and Artemis, Bianca makes the decision to become a Hunter. She shows signs during the quest of being a child of Hades when she

is able to slay some of the skeletal warriors easily when the others were unable to. Bianca later joins the quest, but she dies halfway through the adventure. She stops to pick up a Mythomagic figurine of Hades, which, according to her, is the only one that Nico doesn't possess. However, as the other quest members have warned, removing an item from the Junkyard of the Gods causes a malfunctioning Talos robot to attack them. Bianca goes inside the machine to stop it, but in the process crashes the robot into some power lines. Percy, Grover, Thalia and Zoe search for her from when the incident happened until dawn, but they never found her. When Nico learns of her death at the end of the book, he blames Percy. He believes Percy has let her die despite promising not to let Bianca be harmed. Nico flees, and Percy discovers in the process that the di Angelo's are children of Hades.

The Battle of the Labyrinth
Percy finds out that Bianca was sending him Iris-messages so he could see what Nico and the Ghost King Minos were up to.

Later in the book, Bianca comes back as a ghost, through a ritual by Nico. She explains to Nico that her death wasn't Percy's fault and there was nothing he could have done to help, as she made the fatal decision herself. She also tells him he must forgive Percy, as holding grudges is the fatal flaw of a Hades child. This allows her brother to make amends with Percy and ensure he is on the gods' side for the war.

The Last Olympian
In The Last Olympian, she appears to her brother when he tries to summon their mother's spirit. She warns Nico not to summon her; explaining that she is the one ghost he is not allowed to summon and that she has been hidden by Hades due his grief over her death. Instead of summoning her Nico sees a memory from his early childhood where Maria was killed by Zeus in attempt to get to the children.

The Son of Neptune
In The Son of Neptune, Nico mentions to his half-sister Hazel Levesque that Bianca elected to be reborn, presumably trying for three rebirths and three selections for Elysium, so that she could earn entry into the Isles of the Blest. Nico is saddened by this as he was trying to sneak her out of the underworld and no one would have noticed because Death has been captured. Instead of sneaking Bianca out, he snuck out Hazel. At first pretends not to know Percy Jackson when he came with his memory gone.

Personality
Bianca is quiet and shy, and loves her brother, but dislikes caring for him all the time, and was relieved to be able to be her own person when she joined the Hunters of Artemis. She got along well with Percy, but he was angry with her when she joined the Hunters instead of coming to Camp Half-Blood, as this made him feel as if losing Annabeth had been for no reason at all and that she was also being selfish with Nico. He later forgives her, as she told him she joined the Hunters so she could live her own life and that she felt Camp Half Blood would be safe for Nico for she believes that there are a lot of people like Percy there.

Her father, Hades, mentioned that Bianca would have made a better child of the prophecy than Nico.

Bianca and Nico have a habit of gesturing with their hands while talking and when they are on edge.

Appearance
"I was amazed at how different she looked after just a few days with the Hunters. Her dark hair was braided, so you could actually see her face. She had a splash of freckles across her nose, and her dark eyes reminded me of someone famous, but I couldn't think who."

- Percy thinking about Bianca in The Titan's Curse.

Bianca has black eyes that are like her father's, which gleam with either madness or genius, and silky dark hair. She is lean and about average height. She has olive skin, and used to wear a floppy green hat that hid her face. She gains the silvery aura all Hunters have after she pledges herself to Artemis, and doesn't hide behind her cap anymore. She pulls her hair back into a braid like the other huntresses. Her skin glows silvery, because of her being a Hunter.

Abilities
Bianca doesn't show many demigod powers throughout the series, but she can probably summon the dead like Nico is able to. However, in The Titan's Curse, she managed to kill one of the Skeleton Warriors by stabbing it, causing it to burst into flames. This is most likely due to her parentage, being a daughter of Hades.

As a Hunter of Artemis

 * Immortality, unless she dies in battle or falls in love.
 * Superhuman accuracy and hunting skills like running, jumping, stealth etc.

As a Daughter of Hades

 * In The Battle of the Labyrinth, she (as a ghost) was shown to have dominion over the dead as they parted before her when Nico summoned her.
 * In The Titans Curse, she is the only one who is able to kill the skeletons, which no one else could. It is highly likely that she was able to this because of her father's power over the dead.

Fatal flaw
Bianca di Angelo's fatal flaw may also (like her full-blooded brother Nico) be holding grudges. After her death, Bianca says that holding grudges is the demigod children of Hades' fatal flaw. 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. It may also be a strong bond with those she loves (Nico). This may be because she was killed because she picked up a metal figurine of Hades, the only Mythomagic figure Nico didn't have, an act of misplaced sibling love.

Trivia

 * She, Nico di Angelo and Thalia Grace are the only Greek Half-Bloods of the Big Three whose aging has been tampered by their godly parent, which differs them from Percy greatly.
 * Her first name "Bianca" means "White" in Italian, referring to her fathers albino like skin.
 * Her surname "di Angelo" means "of the angels" referring to death.
