Hazel Levesque

"I'm not choosing one of your paths. I'm making my own."

- Hazel to Hecate

Hazel Levesque is one of the seven heroes of the Prophecy of Seven. She is a fourteen-year-old Roman demigod, the daughter of Pluto and Marie Levesque, and the half-sister of Nico di Angelo. She is a Centurion of the Fifth Cohort and is currently in a relationship with Praetor Frank Zhang.

Early Life
On December 17, 1928, Hazel was born to Marie Levesque and the god Pluto in New Orleans, Louisiana. Marie had summoned Pluto using a spell that Hecate had found, and they fell in love. When Pluto granted Marie one wish, Marie wished for all the riches of the earth from Pluto, despite his warning that the greediest wishes cause the greatest sorrows. She did this mainly because she was tired of being poor as described in the Son of Neptune. Her mother's ambition to become wealthy later caused her grief, as Marie began to use Hazel's unique powers (a result of her wish) for selfish reasons. The jewels that Hazel collected were cursed and would cause the buyers to suffer. Marie Levesque refused to admit her part in Hazel's curse and told her it was Pluto's fault alone.

Moving North and Losing a Friend
Hazel did not have many friends during her childhood with the exception of Sammy Valdez, whom she loved and had shared a kiss just once but after moving to Alaska, where the gods had no power, she never saw him again. Her mother became unstable because she was being influenced by Gaea and when Pluto came to protect them, he'd realized he'd lost her forever. Marie moved them to Seward, Alaska, beyond the power of the gods, despite the many protests by Pluto.

Sacrificing Herself
It was there that Hazel was forced by Gaea to raise her oldest Gigantes son, Alcyoneus, by calling forth precious metals that were beneath the earth on a phantom island. Once Hazel had almost finished the job, she discovered that Gaea also needed a human sacrifice in order for her son to rise up and Hazel's mother offered to be the sacrifice to save Hazel as Gaea promised her Hazel would not be harmed if she sacrificed herself. Once Hazel discovered the treachery, she called up all the riches below her, causing an eruption that broke the cavern walls and ultimately destroyed the island. Hazel and her mother both died in 1942, but delayed the rise of the Gigantes for some time.

The judges of the Underworld had an argument over where to put Hazel and Marie. They decided that Hazel and her mother would go to the Fields of Asphodel after Hazel gave up her chance to go to Elysium in order to save her mother from the Fields of Punishment.

Returning to Life
Nearly seventy years later, Nico di Angelo, a son of Hades and thus her half-brother, found her there, and, seeing that she was a child of Pluto, he brought her back to the world of the living due to the Doors of Death being open. Initially, he had been there to rescue his other sister, Bianca di Angelo, but he was too late as she had tried for rebirth.

Once Hazel was restored to life, she began experiencing "blackouts" of her horrible past whenever she tried to think about them. Eventually, she made it to the Wolf House and, consequently, Camp Jupiter, where she was made a guard at the entrance to the Caldecott Tunnel. The blackouts usually happened when she either remembered her past, or when she thought too deeply about her old life. Later, Hazel pulled Frank Zhang into one of her blackouts, where she replayed the time when she stood before the judges of the Underworld as they decided where she would stay. Afterward, she seems to have no more blackouts. It was a very thankful feeling for if it happened in combat she might have died. Also, Pluto had told Hazel before their departure of Alaska that a descendant of Neptune would wash away her curse. Firstly, she thought of whom to be Percy, but Frank had also been a descendant and so Hazel is not sure who it might be.

The Lost Hero
Hazel is remembered by Jason Grace as one of his friends. She knew Jason for about a month before he disappeared, although this is not noted until the second book in the series.

The Mark of Athena
While arriving at Camp Jupiter on the Argo II, Annabeth Chase saw Percy on the ground with his arms around Frank and Hazel, as if they were old friends. Annabeth, Jason, Piper McLean, and Leo Valdez then enter the Forum where Annabeth worries that she and Percy may have started a relationship. She quickly dismisses the thought, pairing her with Frank instead. After the attack on New Rome, Hazel and Arion cause a distraction to let their friends escape. She later reunites with the others in Utah, where she wonders if Leo is Sammy Valdez. When Leo tells the seven that they need supplies, she accompanies him to the Salt Lake. They soon come across Nemesis where Hazel sees one of her past teachers. Nemesis tells them to find her brother by the Kalends of Juno. She also tells them that unless they stop the giants by the same day that Rome would be destroyed. She then vanishes. Hazel and Leo share many romantic awkward moments until running across Echo and Narcissus. While Leo and Echo distract the cursed boy, Hazel manages to steal a sheet of Celestial bronze with her powers and flees with Leo toward the Argo II.

Hazel is later seen when Piper attempts to get rid of the eidolons, helping to catch Jason after they are banished. She later fans her face and seems flustered after Percy and Annabeth are caught alone together in the stables. Hazel later heads with Piper and Annabeth to Charleston Park where they meet Aphrodite. The goddess tells Hazel to fix her clothes so she could look even more beautiful. The trio are later surrounded by Octavian and Romans, but Percy manages to save them. Hazel, Piper, and Percy stay on board while Annabeth heads into Fort Sumter to rescue Jason, Leo, and Frank, and find the map to help her on her quest.

After they make it into the Atlantic Ocean, Hazel shows Leo a flashback of her life. There, she explains that Sammy was her boyfriend and he and Leo look exactly the same. One of Leo's memories take over, and Sammy is revealed to be Leo's great-grandfather and that he met Hera, who told him he won't live to see Hazel's greatest danger. The flashback ends and Leo and Hazel start to talk about what they saw. However, the group is attacked by a skolopendra nicknamed Shrimpzilla, and she tries to help Leo unleash Greek fire to destroy it. Gleeson Hedge then tells the crew that Hazel and Leo were holding hands much to Frank's horror. However, Hazel, Leo, and Frank are taken overboard and land in the underwater city of the ichthyocentaur. Leo explains everything that really happened while Hazel quickly makes friends with the icthyocentaur and they reunite with their friends.

Hazel stays on the ship while Jason and Piper meet Hercules. She is later tied up and taken captive by Chrysaor along with the rest of the crew except Frank. After Percy and Frank defeat him by tricking his crew into thinking Dionysus was on the ship (even though Chyrsaor wasn't convinced, he still had to flee with the rest of his crew), the crew reach Rome, Italy. Hazel, along with Frank and Leo, track Nico di Angelo into the Pantheon. Leo soon uncovers a tunnel that Hazel volunteers to investigate. However, the eidolons attack once again and force Leo and Frank into the tunnel. The trio soon enter a workshop filled with inventions created by Archimedes that Leo becomes fascinated by. Hazel and Frank are soon tasered to unconsciousness by a Taser Ball possessed by an eidolon. Two eidolons possess unworkable machines and threaten to kill Leo with them. Frank wakes up in time to guard Hazel as Leo destroys the eidolons with Archimedes' sphere. Leo sadly tells Hazel that she was tracking Nico by his sword. Hazel, grief-stricken, then asks where Nico could be. Gaea laughs in the trio's faces, and shows them that Annabeth is facing her mother's mortal enemy and Jason, Piper, and Percy are drowning.

Hazel appears again with Leo, Frank, and Coach Hedge as they enter the Colosseum, rescuing Percy, Jason, Piper, and Nico. Leo tells them he had thought of an escape plan. Hazel reunites with Nico, who informs them that the mortal side of the Doors of Death are in The House of Hades. Leo, Hazel, and Frank inform that Gaea had shown them Annabeth was in trouble and they head out to rescue her. The Argo II and its crew arrive at Arachne's lair where Annabeth has barely survived the experience. Jason, Piper, Leo, and Frank secure the Athena Parthenos to the Argo II when Annabeth is dragged into a pit. Hazel desperately warns them to cut the spider silk as Nico tries to save Percy and Annabeth. Percy grabs on to Annabeth as Hazel continues to plead for help. However, Percy makes Nico promise he'll take the four to the House of Hades while he and Annabeth fall into Tartarus.

Hazel, Jason, Piper, Leo, Nico, and Coach Hedge, all aboard the Argo II, then decide to follow Percy's orders and set sail to Eprius, Greece to save them from the House of Hades.

The Blood of Olympus
Hazel uses the Mist to make Jason appear as an old man and Piper and Annabeth as his hand maidens as they go to defeat the one hundred suitors of Penelope.

She, Frank and Leo head to Delos to find the twin archers to retrieve the Curse of Delos. She and Frank leave to talk with Artemis in private.

When the seven reach Athens she masks Annabeth and Percy as earthborns. The seven then assault the giants and have an edge on them for a while but eventually lose control of the situation. When the gods come and aid them, she fights alongside Hecate. When the seven reach Camp Half-Blood they aid the two camps if fighting off Gaea and the monsters. When the remaining seven and Nico meet after the battle, she and Frank tell them of Leo's plain, while the others are mad at them for doing this they soon forgive them. The night before she goes back to camp she stays with Nico in cabin 13. She reveals to her brother that she has become Centurion of the Fifth Cohort; Nico jokes about it by asking if there are regulations regarding Centurions dating praetors. Frank then pops in to say goodnight to her. She and the rest of the Romans leave the next morning.

Percy Jackson's Greek Heroes
Right after finishing his narration of this book, Percy reveals that after the events of The Blood of Olympus, he, Hazel, and the rest of the Seven started the tradition of monthly Argo II reunion parties, and he is quite worried about being late to the current one.

Between the Series
Several days after the deaths of Gaea and Leo, a parchment scroll with a holographic message, sent from the resurrected Leo, came fluttering into Camp Half-Blood on the wind. Hazel and Frank, while angry at Leo for his long absence, are extremely relieved to learn that he is alive.

It can also be assumed that Hazel rarely visits her brother Nico, as the latter describes her and Frank being busy "doing the Twelfth Legion thing” at Camp Jupiter.

The Hidden Oracle
Hazel is not present at Camp Half-Blood when the depowered Apollo and Meg McCaffrey arrive, so Nico explains where his sister and the rest of the Seven are now, while showing Leo's holographic message.

The Dark Prophecy
Leo mentions the daughter of Pluto, saying it would be good to see her again.

The Burning Maze
Leo mentions Hazel when telling Apollo and the others that she survived Caligula’s assault on Camp Jupiter.

Appearance
Hazel is African American with shoulder-length curly cinnamon brown hair and gold eyes. She is marked with a glyph, the letters SPQR, and one stripe for one year of service that she received only a few weeks before Percy arrived. Frank and Leo consider her to be very pretty, while Percy says that Hazel's mother looks just like Hazel, saying Marie Levesque was "beautiful." Percy also describes Hazel as being "darker-skinned," and when Hazel is describing her mother later on she mentions that they had the "same dark complexion, brown as a roasted coffee bean." Also, when patrolling Frank's grandmother's house, Frank talks about how Hazel wore this shirt and jacket, "that made her skin look as warm as cocoa." She is toned and fit and is the shortest of the seven demigods, though she is also the youngest, in stark contrast to Frank Zhang, the tallest of the seven and third oldest.

Personality
Hazel is bright and outgoing with a love for creativity and horseback riding, but a has dislike for boating and curses. Percy states that she was a great comfort to him and Frank, at times even saying that she seemed confident. Percy also describes her as being very mature for her age, although he felt a little uncomfortable when he started depending on her for comfort, but was glad she was there. Hazel tends to ignore others at times for her own preferences. For example, she carries a cavalry sword while not owning a horse to ride into battle on and she originally didn't want to like Frank because everyone at Camp Jupiter said they would end up together.

She feels a massive amount of guilt over releasing Alcyoneus, and thinks it's her responsibility to bring him down. Hazel can also be easily embarrassed, such as through Frank's clumsiness and his attempts to comfort her. Hazel is extremely loyal to her friends and treats them as family, as shown through her friendship with Frank and Percy, as well as the rest of the Fifth Cohort and when she gave up Elysium to go to the Fields of Asphodel so that her mother wouldn't go to the Fields of Punishment. She is also very affectionate, having kissed Percy, Frank, Leo and Nico on the cheek multiple times though most of the time, she gives them sisterly kisses.

Abilities
General Abilities= As a child of the Big Three and one of the seven, Hazel is an extremely powerful demigods with power only rivalling that of other children of the Big Three. Being a daughter of Pluto, Hazel is a child of the Big Three, therefore an extremely powerful demigod, she has the following ablilities:
 * ADHD: Like most demigods, Hazel possesses inborn supernatural battle reflexes and senses that she uses to analyze the fighting style of her opponent.
 * Fighting Skills: Hazel is a very skilled user of her Spatha, able to defeat many trained legionnaires in The Son of Neptune during the war games, despite them having more experience than her, she was also able to hold her own very well fighting Clytius by herself, when it took the other 5 demigods and a goddess to defeat him, Hazel held her own against Clytius even though she was in an incredibly weak state, and she was able to hold her own very well with Alcyoneus a giant that is meant to oppose Hades/Pluto and his children, and ultimately defeat him with some help from Frank Zhang in  The Son of Neptune. Hazel was able to fight off these two very strong and ancient giants by herself therefore. In the Second Giant War Hazel is able to hold her own very well against  multiple giants, ultimately defeating Alcyoneus with the help of Arion again and wounding other giants.  Also, Hazel is able to teach swordsmanship to Piper and train her to also become a skilled swordswoman.
 * Dyslexia: Hazel's brain is "hard-wired" for Latin.
 * French (limited): Hazel speaks Louisiana French, having studied it in school, though she is not fluent. However, her French is so very different from Frank's Canadian French, that they can barely communicate.
 * Wolf Stare(assumed): Since Hazel is a trained Roman, by Lupa it can only be assumed that Lupa taught her the wolf stare in the Wolf House.
 * Superhuman Strength : Being a demigod, Hazel is stronger than the average mortal.
 * Superhuman Agility : Being a demigod, Hazel is more agile than the regular human being and has much faster reactions.
 * Superhuman Durability : Being a demigod, a Hazel is more durable than the average mortal, as shown as she survived being hit by a giant, and shook off being hit by one of the strongest giants while travelling at supersonic speed on her horse, Arion.
 * Skilled Trainer: Hazel is shown to be a skilled trainer, as she trained Piper at sword fighting. Piper was able to even go toe to toe with the giant, Periboia and fight the giant, Mimas, because of Hazel's training.
 * Leadership: Hazel is shown to be a great leader as she is a Centurion of the Fifth Cohort.
 * -|Demigod Abilities=
 * Geokinesis: Hazel can find any underground caves, tunnels, trapdoors, cause earthquakes, and change their shapes to suit her needs or destroy them. She was able to find a secret underground tunnel during the War Games in The Son of Neptune. In The House of Hades, Hazel was able to bend the tunnels she fell through back towards Pasiphaë.
 * Chrimatakinesis (limited to precious metals and gems): Hazel can control valuable gems and metals.
 * Ferrokinesis (limited to precious metals): Hazel can sense and summon precious metals from under the ground as well as manipulate them, and change it's shape.
 * Sensing Riches: She can also use this ability to sense precious metals or materials, such as gold, silver and diamonds from under the Earth. In The Mark of Athena, Hazel is able to sense the Stygian Iron of Nico's sword.
 * Summoning and Controlling Riches: She can summon and control tons of precious metal and jewels simultaneously, as shown when she fought with the Amazons named Lulu and Doris; leaving them buried in a mountain of jewelry and when she lifted all the gold in the Gryphon's nests. She had even summoned a dozen of rubies at the giant, Clytius with so much force that it punctured his metal armor and even staggered the giant and wounded him.
 * Telumkinesis (limited): Because Hazel has her Ferrokinesis, she has some control over weapons but not as much as control as a child of Ares would have. This was shown when she summoned Jason's golden gladius from the ocean.
 * Mist Manipulation/Mystiokinesis- According to Hecate in The House of Hades, Hazel has a great potential to perform magic and manipulate the Mist. Her mother had this ability as well, but Hazel's potential is even greater. She has begun to master this new skill, having successfully tricked Sciron and even defeated the more experienced and powerful sorceress Pasiphaë. By The Blood of Olympus, Hazel was capable of conjuring up persuasive illusions, making Percy and Annabeth appear as Earthborn giants, and make Jason appear as an old man.
 * Mist Travel: During the final battle with the Giants in The Blood of Olympus, Hazel displayed the ability to disappear into the Mist and appear again to strike the enemies.
 * Mist Placement: During her battle with Clytius Hazel has displayed the ability to use the Mist to take objects that are far away from her, and place them right behind her seen in The House of Hades when Hazel used the Mist to take a half dead Percy and Annabeth and over powered Leo who were being choked to death in a dark black smoky mist by Clytius and placed them behind her.  She has also displayed this ability when she put the bandit Sciron in front of the cliff, making Jason able to kick him off. ,
 * Death Sense: Much like her half-brother Nico, Hazel states in The Son of Neptune that she can sense death, or a creature that has died like the basilisks that Gray killed. She was also able to sense Gray, an undead warrior that returned to the Earth after it had killed the monsters, before she saw it. Leo also noted in The Mark of Athena that Hazel and Nico shared a look likely comparing children of Hades/Pluto "death radar" notes when Percy and Annabeth fell into Tartarus. However, her sense seems to be somewhat weaker than Nico's, as only the latter was able to tell when Percy and Annabeth had approached the Doors of Death in The House of Hades. Her powers were enough however to allow her to see and sense the powers of the Doors of Death which only Nico and Jason were able to do.
 * Shadow Travel: In The House of Hades, she and Nico are able to shadow-travel themselves and six other demigods out of the Necromanteion and back to the surface, despite Hazel stating that she had never tried to shadow-travel before that instance. However, it is assumed that shadow travel takes away a lot of her energy.
 * Flashbacks: Hazel is able to look back at events from her life before she died. At first she is unable to control when these flashbacks would happen as they would be triggered by thinking about the past too long. Eventually she gained the ability to control them after having shared a flashback with Frank Zhang in The Son of Neptune. She has some control over what she sees after this and is able to show Leo Valdez a memory of Sammy Valdez from her past in The Mark of Athena, but is then taken into Leo's memory, something she didn't expect. Nico thinks this happened because of her time in the Underworld, but it is still unclear how this power works.
 *  Necromancy (possibly): It is unknown whether she can actually utilise this ability but since most other children of Hades were able to summon and control the dead, it is assumed Hazel can too.

Magical Items

 * Spatha: Hazel fights with an Imperial Gold spatha, a Roman cavalry sword.


 * Frank's stick: In The Son of Neptune, Frank trusted the daughter of Pluto with his life line which she has kept for most of their quest to Athens. However, after Leo gave Frank a fire-proof bag to keep the stick in, Hazel gives it back to Frank, feeling a little disappointed in having to give it back.

Love Interests
Frank Zhang= Hazel's current love interest is Frank Zhang. The two are shown to be good friends in The Son of Neptune and are shown to have feelings for each other, though secretly.

As the two take off on the quest to Alaska with Percy, Frank reveals that he knows of Hazel's secret that she came back from the dead. The two experience a blackout together as they live through Hazel's last moments in her previous life and her experiences in the Underworld. While they are standing in the Fields of Asphodel, waiting for Hazel to return to life, Frank tells Hazel of his secret: that his life depends on a stick. The two wake up at the same time to a worried and slightly irritated Percy.

Later, after the battle, Hazel tells Frank of her affection and the two share a kiss. Later, the two are said to be dating, but the arrival of Leo Valdez adds a few complications to their relationship. While Frank is loyal to Hazel, she seems to be drawn to Leo because of his similarities to Sammy. This leads to Frank becoming annoyed by Leo and even starts a fight between herself and Frank.

In her former life, Sammy Valdez was Hazel's only friend and love interest. He used to take care of horses for rich people and on weekends, and would take Hazel out to ride. They became boyfriend and girlfriend for a brief period of time before Hazel moved away with her mother to Alaska under the influence of Gaea.
 * -|Sammy Valdez=

In the Underworld, it is revealed that if Gaea hadn't intervened and Hazel's mother had not forced her to move away, Hazel would've married Sammy and lived a long happy life. Instead, Sammy moved to Texas, married, had kids, and died. It is seen though that he never forgot about Hazel and it was shown that he loved her up until he died.

Friends
Percy Jackson= Percy and Hazel first met in The Son of Neptune and quickly grow to become very close friends. Hazel admits to herself that when she first saw him, she thought he was a god in disguise. Also that he had "the good looks of a Roman god" and "an aura of power." They are good friends, with Hazel looking to Percy as a friend and a leader and Percy viewing Hazel as someone he can rely on. During times of distress or confusion, Percy and Hazel comforted each other like siblings, and gave advice in a sibling manner, and she gave him a sisterly kiss on the cheek. Hazel is at times a little awed by Percy's powers as the son of Poseidon. She was once told by her father, Pluto, that a descendant of Neptune would free her from her curse and wonders if Percy is the one he was talking about.

In the The House of Hades she considers Percy the "backbone" of the Prophecy of Seven. Here it is revealed that Percy is probably the demigod she admired the most, along with her brother Nico. When Percy and Annabeth emerge from the Doors of Death weak and breathless, Hazel uses the Mist to distract Clytius from them.

In The Blood of Olympus, at Leo's insistence, Hazel doesn't reveal his suicidal plan to Percy. After Leo's death, Hazel breaks down crying and reveals the truth to Percy, who initially looks furious, but his rage quickly dissipates by the time Hazel is done explaining, since Percy admits that staying mad at her was hard when Hazel was crying, and the plan sounded like the exact thing that Leo would have done.

Hazel, Frank and Reyna let Percy and Annabeth know that they can live in New Rome as long as they'd like after completing the senior year of high school. As mentioned in Percy Jackson's Greek Heroes, Percy and Hazel have remained in contact during the year after Gaea and the Giants' defeat, with both of them attending monthly Argo II reunion parties. Jason remembers Hazel in the last part of The Lost Hero as being a friend of his back at Camp Jupiter. In The Son of Neptune, Hazel tells Percy that after she arrived, she had only known him for about a month before he disappeared, so they hadn't known each other well. Through Hazel's point of view, it is assumed that she and Jason were friends. She even compares Jason to Percy, stating that they both had the same look, as if they had both seen their fate, and were waiting for it to happen.
 * -|Jason Grace =

When Hazel and Jason both confront Sciron, in The House of Hades Hazel notes that she couldn't figure Jason out well, as he acted "too perfect", and that she would rather have Nico, Frank or Percy at her back. Still, Hazel does trust Jason, and they cooperated well in defeating Sciron.

In The Blood of Olympus, at Leo's insistence, Hazel doesn't reveal his suicidal plan to Jason. After Leo's death, Hazel breaks down crying and reveals the truth to Jason, who initially looks furious, but his rage quickly dissipates by the time Hazel is done explaining, since Jason admits that staying mad at her was hard when Hazel was crying, and the plan sounded like the exact thing that Leo would have done.

As mentioned in Percy Jackson's Greek Heroes, Jason and Hazel have remained in contact during the year after Gaea and the Giants' defeat, with both of them attending monthly Argo II reunion parties. Hazel and Leo first meet in The Mark of Athena, but first sees him in a video scroll during The Son of Neptune. They are very awkward around each other because she thinks that Leo looks so much like her first love, Sammy. Leo, despite thinking Hazel is beautiful, constantly feels her examining him and is confused when she acts like they have met before. He also tries to avoid her to a small degree as he knows that Frank is dating her. However, the two keep finding themselves in awkward situations that leads to a fight between Hazel and Frank.
 * -|Leo Valdez=

Their connection to each other is slightly cleared up when Hazel uses her ability to show people the past to show Leo who Sammy was. During this flashback, it is shown that Sammy is Leo's great-grandfather and that he asked Leo to look after Hazel for him. Despite learning this information, the two are still somewhat shy of each other. In The House of Hades, most of the rough patches in their relationship are smoothed out, and they act more openly friendly towards each other. When Leo returns from Calypso's island, she kisses him on the cheek, showing that she loves him as a brother. She is also instantly able to see that Leo has fallen in love, something nobody other than Jason could guess. Later, when she and Leo get stuck in the Necromanteion, Hazel apologizes for telling Leo about Sammy, but Leo fully embraces his identity as Sammy's "stunt double" and encourages Hazel not to question her relationship with Frank.

In The Blood of Olympus, it is revealed that Hazel had finally gotten Leo to spill about Calypso. She then sketched him a picture of her based on the description that he'd given her. Shortly thereafter, Leo tells his suicidal plan only to Hazel and Frank, since they, as Romans, would understand the importance of sacrifice. Touched by Leo's heroism, Hazel and Frank tearfully embrace Leo in a group hug and support his plan, even though they despise it. Hence, when their plan of successfully resurrecting Leo after Gaea's defeat seemingly fails, Hazel is understandably devastated, and hesitant to ask Nico if he'd felt Leo's death. Piper and Hazel first meet in The Mark of Athena, and seemed to be on good terms. Hazel encouraged Piper to coerce the Eidolons to leave, and Piper comforted Hazel after Jason and Leo accidentally insulted her by questioning Nico's loyalties.
 * -|Piper McLean=

In The House of Hades, both are the only girls left on board the Argo II, which allows them to bond and become good friends. Hazel would constantly train Piper in swordsmanship (with great success), while Piper would attempt to help Hazel control the Mist by telling her about Charmspeak. They also enjoy laughing about the bad habits of the boys, and had a number of good private talks, while also sharing tears about Annabeth. Both of them also rush to hug Leo right after he returns from Ogygia.

Hazel is impressed at how skilled a swordswoman Piper has become by The Blood of Olympus. At Leo's insistence, Hazel doesn't reveal his suicidal plan to Piper, and magically tricks the latter into believing that she has the actual Physician's Cure. After Leo's death, Hazel breaks down crying and reveals the truth to Piper, who initially looks furious, but her rage quickly dissipates by the time Hazel is done explaining, since Piper admits that staying mad at her was hard when Hazel was crying, and the plan sounded like the exact thing that Leo would have done. In the several days after that, Piper and Hazel, along with Annabeth and Reyna become inseparable, as they help the camps get along after Gaea's defeat. Hazel valued Piper's skills as a go-between to smooth over any conflicts. The evening after Hazel leaves, Piper already misses her, claiming that the camp now feels somewhat empty without her and the other Romans.

As mentioned in Percy Jackson's Greek Heroes, Piper and Hazel have remained in contact during the year after Gaea and the Giants' defeat, with both of them attending monthly Argo II reunion parties. Dakota is Hazel's superior in their branch of the legion. He had apparently stood for Hazel when they were deciding on cohorts and the two have been teammates for a few months.
 * -|Dakota=

Family
Marie Levesque= Marie Levesque is Hazel's mother. She is the one responsible for Hazel's curse. She was a fortune teller and a jewel seller who once summoned Pluto using a spell that Hecate granted her, and Pluto courted her. Later, he swore on the River Styx that he would grant her anything she wished. Marie, who had been poor her entire life, wished for all the riches in the earth. Pluto warned her of the curse it would bring, but still granted her the wish, and thus, Hazel's curse.

Marie is said to be selfish in the beginning. She was under Gaea's spell and blamed Hazel for her curse. Under Gaea, she uses her daughter and the two go to Alaska to avoid the gods. Hazel is then used by Gaea to resurrect Alcyoneus.

At first, Marie is thought to hate Hazel and think that she is a cursed child. In the end, Marie reveals that she loves Hazel and that Hazel is the one greatest treasure in her life and attempts to sacrifice herself in order to save Hazel, even if that meant that Alcyoneus and Gaea would rise. Hazel, in order to stop Alcyoneus' rise, sacrifices herself. She drowns with her mother holding her in her arms and they manage to delay the rise of the Gigantes for another couple of decades.

Although they are only half-siblings they refer to each other as "brother" and "sister" and are shown to deeply care for each other. Nico tends to look out for her and worries about her flashbacks before she is able to control them. In The Mark of Athena, when Jason and Leo express doubts about Nico's loyalty to the gods, she gets incredibly furious and storms out of the room. She was also determined to go to Rome to save Nico despite knowing it could be a trap. After Nico is saved and she sees his broken state, Hazel tries her best to comfort him.
 * -|Nico di Angelo=

In The House of Hades, when Hazel is dying of poison, Nico goes as far as threaten a minor god to heal her, which results in him being turned into a plant. Later, he kisses Hazel on the cheek as if saying goodbye, to the surprise of Piper. After rescuing Hazel from a giant at the Doors of Death, Nico comes over and kisses her forehead and claims that Hazel 'would have made dad proud', this sentimental compliment may have reminded Nico of his sister Bianca, who Hades initially considered better than him in every way. Hazel cups her hand around his face and smiles at him, showing they have a very close relationship. She thinks herself very lucky to have a brother like Nico. Still, even she knows nothing about Nico's love for Percy.

In The Blood of Olympus, when Hades reveals to Nico that one of the Seven is destined to die, Nico's primary concern is for Hazel. They are finally reunited after Gaea and the Giants' defeat, and Nico is happy to live with a sister again, even if only for a few days. While he's unable to forgive himself, Nico does his best to comfort Hazel about Leo's death (which he himself had felt happen), assuring her that she is blameless. Nico is impressed and proud at how far Hazel has come since he brought her to camp, having become both powerful and confident. He claims that while getting a second life is one thing, making it a better one that the first is what actually matters. He approves of her relationship with Frank, and promises to visit them often in Camp Jupiter.

Hazel has only meet her father Pluto a few times. It is clear that Pluto cares about his daughter very much, giving her birthday presents, and apologizing for unwillingly cursing her. Also, it is Pluto who tells her that her curse will one day be washed away by a descendant of Neptune.
 * -|Pluto=

Later, in The Son of Neptune, after Thanatos has been freed and the monsters defeated, Hazel asks him if she is on the list of escaped souls. Thanatos tells her that she is not on the list, but offers to double check. Hazel declines the offer. Hazel is later asked if Pluto has visited her. She replies that he has not, but notes that this may be a gift to her, as if he acknowledges her existence, she may have to return to the Underworld. This shows how much Pluto cares about her.

In The House of Hades, after Hazel prays to her father for help, it is implied that he sent Arion to her, so that she could talk to Hecate. After Hazel's first successful use of the Mist, Pluto is so proud that his Greek and Roman forms momentarily unite, and he is able to appear before her to give advice on fighting Pasiphaë.
