|“||Certamente. We will stay together. Zeus is un imbecile.||”|
While searching for Ethan Nakamura in the Underworld, Melinoe, the goddess of ghosts, appears before Percy Jackson, Thalia Grace, and Nico di Angelo to torment them with visions of people they had lost. While she appeared to Thalia as her mother, she showed herself to Nico as Maria di Angelo.
When trying to summon Maria, Nico instead finds out much information about his mother through the ghost of his sister, Bianca di Angelo.
During the time Maria and Hades were together, the Great Prophecy had been spoken and World War II was beginning, with some of his other demigod children involved on the side of the Axis Powers. Hades wanted to hide Maria and theif children in the Underworld so that Zeus wouldn't be able to find out about them. However, Maria refused to raise her children there as they would be away from her family.
While she was in a hotel, Zeus destroyed it, killing Maria. Hades was only quick enough to shield their two children, Bianca and Nico. Hades had wished to revive her in his loss, but Alecto, the Fury, reminded him that as an immortal, he had to respect the forces of life and death. A devastated Hades then told Alecto to bring Nico and Bianca to the Lotus Hotel and Casino, where time stands still. Hades had his children taken to Lethe to have their memories wiped. Maria's tragic death caused Hades a lot of devastation and bitterness towards his family, which in turn lead him to the curse the Oracle, who warned Hades to hide his children sooner.
Several years later, Nico was able to partially use the memory of his mother to convince Hades to fight with the other Gods: he told Hades that Maria was right about families sticking together and his father should prove himself to be more than what his siblings thought of him.
AppearanceMaria was described to be a very beautiful woman, whom both of her children resemble, especially her daughter. She had dark hair, dark brown eyes and a smile similar to Bianca's.
In The Sword of Hades, Percy described Maria as a woman in an old-fashioned black velvet dress with a matching hat. She wore a string of pearls and white gloves, and her hair was tied back.
In The Last Olympian, Maria wore a black dress, gloves, and a black veiled hat like a star from an old 1940s movie.
Maria was one of those rare few who saw Hades' kind and generous side. She speculated that if the other Olympians saw it as well, they wouldn't spurn and fear him nearly as much. They had two children together and continued to see each other until Bianca and Nico were about 5 and 3 years old, respectively.
It is evident that Hades had loved Maria dearly; gods rarely revealed their true nature to a mortal, even if it was one he or she loved and had children with. He was prepared to disregard Persephone (his own wife) by promising to build his family a palace of gold to live in if she would agree to go to the Underworld with him. Unfortunately, while she was in a hotel, Zeus destroyed it, killing Maria. Hades was only quick enough to shield Bianca and Nico. Hades was left devastated while witnessing Maria's death and wished to revive her in his loss, but Alecto, the Fury, reminded him that as an immortal, he had to respect the forces of life and death. Maria's tragic death caused Hades a lot of pain and bitterness towards his family, which in turn, lead him to the curse the Oracle.
Nico lost all of his memories about Maria because Hades had Nico and his sister taken to the Lethe to have their memory wiped. He was so eager to discover more information about his mother from Hades, who uses this to his advantage. He even went as far as attempts to summon Maria despite Bianca warning him that he should not do that.
In his attempt to summon his mother, Nico presented a memory which discusses the terms of the agreement after World War II and how Hades defied it. He watched as Hades and Maria discuss how Hades can bring her to safety, though his offer of building a palace for Maria to lived is declined. He then saw Zeus destroy the hotel they were staying in an attempt to kill him and Bianca. Hades was only quick enough to protect Nico and Bianca but his mother didn't survive. During the Second Titan War, Nico was able to partially use the memory of his mother to convince Hades to fight with the other Gods: he told Hades that Maria was right about families sticking together and his father should prove himself to be more than what his siblings thought of him.
Like Nico, Bianca lost all of her memories about his mother because Hades had Bianca and his brother taken to the Lethe to have their memory wiped.
