Delphini (b. March 1998), known by the nickname Delphi, was a British half-blood Dark wizard, the illegitimate and secret daughter of Tom Riddle and Bellatrix Lestrange. Being the only child of Lord Voldemort, she could speak Parseltongue, and she became the only known living heir of Salazar Slytherin after her father's demise. Delphini was likely imprisoned in Azkaban for the murder of Craig Bowker Jnr, as well as for the misuse of an unauthorized Time-Turner in a failed attempt to bring back her father and his evil reign. 

Biography

Early life (1998–2020)

"I was - unwell - as a child - for a few years. Other people got to go - I did not."

— Delphini regarding why she did not attend Hogwarts

Delphini was born in secret at Malfoy Manor in early March 1998 as the result of a liaison between Bellatrix Lestrange and Lord Voldemort. On 2 May 1998, both of her biological parents were killed in the Battle of Hogwarts. Bellatrix's husband, as well as her maternal stepfather, Rodolphus Lestrange, survived the battle but was sent to Azkaban for his crimes.

This left the young Delphi an orphan, as her father had been. Euphemia Rowle took Delphi in and raised her, allegedly only because she was offered a substantial amount of gold. According to Delphi, Rowle was not fond of her. She kept a pet Augurey and claimed that it cried because it knew Delphi was going to meet a "sticky end".

Delphi did not attend Hogwarts School of Witchcraft and Wizardry. Apparently, she had been unwell as a child and missed several years; as other children got to go, she did not. She apparently had little to no contact with other children, claiming that she did not have a best friend at the age of fourteen and that she even invented an imaginary one when she was younger.

At some point, Rodolphus was either released from Azkaban or escaped a third time. He told Delphi about her true heritage and the prophecy he believed she was meant to fulfil.

An ambitious plan (2020)

Lying low at St Oswald's Home

At some point, Delphi found Amos Diggory, placing him under a Confundus Charm to pass herself off as his niece, Delphi Diggory, and to ensure he did her bidding.

On 31 August 2020, Amos Diggory went to Harry Potter and urged him to use a Time-Turner to go back in time to the Triwizard Tournament and save his son, Cedric, who was murdered on the orders of Voldemort after taking a Portkey to the graveyard in Little Hangleton with Harry Potter.

Harry refused, but his son, Albus, overheard the conversation. Later, along with his friend, Scorpius Malfoy, he decided to help the Diggorys alter history and save Cedric. On their way to Hogwarts for their fourth year, Albus and Scorpius leapt off the Hogwarts Express to enact their plan. The two found their way to St Oswald's Home for Old Witches and Wizards, the nursing home where Amos Diggory lived and where Delphi, posing as his niece, pretended to take care of him.

Infiltration of the Ministry of Magic

Albus, Scorpius, and Delphi sneaked into the Ministry of Magic and stole a Time-Turner, which Delphini helped them accomplish by disguising herself as Hermione Granger using Polyjuice Potion.

Travelling through time

Using the Time-Turner, Albus and Scorpius seriously altered past events, creating two alternative realities, with the first seeing Hermione Granger as the bitter Defence Against the Dark Arts teacher while Ronald Weasley was in a less-than-happy marriage to Padma Patil, and the second seeing a world where the Order of the Phoenix and Dumbledore's Army lost the Battle of Hogwarts. After many attempts, including one where Albus was erased by their changes, Scorpius managed to restore the correct timeline and decided to destroy the Time-Turner on their own, not trusting the Ministry to destroy it.

Albus then sent an owl to Delphi. She arrived at Hogwarts just in time to see how he planned to try to destroy the Time-Turner. Albus wanted to apologise to her and tell her that they would not be able to go back in time to save Cedric. He and Scorpius explained that in the new reality they had created, Cedric's Triwizard humiliation had turned him into an angry, bitter young man who became a Death Eater and eventually murdered Neville Longbottom before he could destroy Nagini, helping to usher in the era of the Dark Lord. Delphi said that Cedric would have understood, suggesting they should destroy the Time-Turner together, and that she would explain to her uncle why Cedric would not be saved.

After Albus handed her the Time-Turner, both boys noticed a black tattoo of a bird on her back. Delphi said it was an Augurey, which reminded her of her childhood as an orphan when she was raised by the Rowle family. The boys realised she was an enemy based on Scorpius recalling references to 'the Augurey' in the timeline where Voldemort won, but Delphi pulled out a wand and bound them together.

Revealing her true colours

Delphi planned to travel back in time to ensure Cedric's survival in the third task of the Tournament (since she was unable to go back to the first two, as the boys' actions made those events too temporally unstable). Albus refused, but she threatened to kill Scorpius. Craig Bowker Jnr, another Hogwarts student, rushed up to say that the whole school was looking for them, but was killed by Delphi immediately, giving her a similar nature to that of her parents, who didn't hesitate to kill.

Delphi took Albus and Scorpius back in time with her, but they refused to cooperate. As Delphi prepared to kill Scorpius, she was struck from behind by an unsuspecting Cedric Diggory, who thought the scene was simply a part of the Triwizard task. He freed the boys before returning to the challenge.

Then Delphi staggered to her feet and picked up the Time-Turner, but Albus and Scorpius managed to grab the device. They raced through time once again, but once they arrived, Delphi destroyed the Time-Turner and flew away.

Albus and Scorpius discovered that they had been transported to 30 October 1981 — the day before Harry Potter's parents were murdered by Voldemort. The boys realised that Delphi intended to stop Voldemort from trying to kill Harry, and thus trigger his own destruction when his Killing Curse rebounded on him due to Lily Potter's loving sacrifice.

Meanwhile, the boys' parents were looking for them. Ron Weasley told Harry he had seen Albus with an older girl the night before. Harry thought he must mean Delphi Diggory, Amos's niece. They went to see Amos, who told them that he never had a niece, which meant that the Confundus Charm Delphi had cast on him had waned.

The adults raced to Delphi's room and found her writings revealing Delphi to be Tom Riddle's daughter and that she believed she could restore him to power following the words of a prophecy.

Confrontation in St Jerome's Church

"You can't remake your life. You'll always be an orphan. That never leaves you."

— Harry Potter's words to Delphi about her father

Albus and Scorpius were able to send a message to their parents by leaving a message on Harry's old baby blanket, treated with a potion that would only become visible when it interacted with another potion Albus had spilled on the blanket shortly before this final trip back through time. Now aware of when and where their children were, Harry, Ginny, Draco, Ron, and Hermione headed back to Godric's Hollow in 1981 using another Time-Turner to help the boys. They found Albus and Scorpius, and all of them hid in a church, from which they could look out for Delphi without being seen.

Harry volunteered to transfigure himself into Voldemort and lead Delphi into a trap. The others planned to wait in the church behind the large wooden doors until Harry was able to lure her inside.

Delphi finally appeared, and Harry (disguised as Voldemort) pretended not to know who she was. She explained that she was the child of Tom Riddle and Bellatrix Lestrange. He told her that together they could become an unstoppable force, but by that time, the transfiguration had begun to fade. She saw that she was actually speaking to Harry, claiming she had studied him and knew him better than her father did. She locked the doors to prevent the others from jumping out to help. Without a wand, Harry was forced to hide beneath a church pew while she attacked him. When Delphi was about to kill him, Albus popped up through a hatch in the floor, throwing a wand to his father. Together, they were able to overpower Delphi.

Delphi begged them to kill her or wipe her mind clean. She claimed that she had only wanted to meet her father and be with him. Albus wanted to kill her to avenge Craig, but Harry stopped him. In a moment of empathy for her, Harry told her that she had to learn to live with the fact that she would always be an orphan, as he had.

Imprisonment (2020–)

Following her defeat, Delphini was presumably imprisoned in Azkaban, most likely for the charges of murder and abuse of forbidden relics.

Physical description

Delphini had long, silvery hair with blue tips, as well as a tattoo of black Augurey wings on her back, near her neck.

Personality and traits

"Are you crawling away from me? Harry Potter. Hero of the wizarding world. Crawling away like a rat."

— Delphini taunting Harry Potter

Delphini was extremely calculating, demonstrating a keen intellect and profound talents for manipulation and exploitation, much like her father was when he was younger. Exactly like Voldemort and Bellatrix Lestrange, Delphini was intensely sadistic, being easily able to cast the Cruciatus Curse with malicious intent and proving to be a dangerous opponent for even Harry Potter. Aside from being malicious, Delphini was independent and highly determined, orchestrating a complicated plan to restore Voldemort without any immediate assistance that she didn't gain through manipulation or exploitation of other people, a trait Voldemort himself had possessed. She was ruthless and easily capable of killing in pursuit of her goals, or even being at the wrong place at the wrong time (i.e., Craig Bowker Jnr), another trait shown by both her parents. Despite being this dangerous for her ruthlessness and intelligence, Delphi was fierce-tempered and could lose control of herself if something didn't go according to plan, which happened to be another trait she had inherited from her parents. Her temper led to her attacking Harry Potter when he was revealed to have been disguised as Voldemort, as she was self-righteously angry that he had fooled her and that he had destabilised her plan so much. When Harry and his friends defeated her, she begged for death or to be Obliviated, indicating that her pride had been crippled by her being defeated by him.

Similar to her father, Delphini had an obsession with Harry Potter to the point that she even claimed that she had studied him and knew him even better than her father ever did during his lifetime.

Despite having a very similar background as her father, such as being raised without knowledge of her parents for a long time after a relationship of a one-sided love (her mother's obsessive love was very much similar to that of her paternal grandmother's), and living under the guardianship of a strictly business-minded party without being loved for their entire childhood, Delphini deviated from Voldemort's consequential inability to love at all. She had demonstrated a tremendous devotion to her father despite not even knowing him personally, and unlike him, she aimed not for conquest, revenge, or destruction, but to simply be with him.

Parents

Bellatrix Lestrange and Lord Voldemort

"My ultimate goal is to bring back my father and mother from death, and we can rule the wizarding world however we want! We kill Muggles, Muggle-borns, and Blood traitors from the wizarding world, and there would be no good or evil in our eyes."

— Delphini to Albus Potter about bringing back her parents from death.

Delphini was born in Malfoy Manor, where her mother, Bellatrix, gave birth to her. However, she grew up in the Rowle family because her parents were killed in the Battle of Hogwarts. Euphemia Rowle, a Death Eater, took Delphi in and raised her, allegedly only because she was offered a substantial amount of gold. She did not attend Hogwarts School of Witchcraft and Wizardry. She had been unwell as a child and missed several years, and while other children got to go, she did not.

She had little to no contact with other children, claiming she did not have a best friend at fourteen and even invented an imaginary one when she was younger. At some point, Rodolphus was released from Azkaban or escaped a second time. He told Delphi about her true heritage and the prophecy he believed she was meant to fulfill.

At some point, Delphi found Amos Diggory, placing him under a Confundus Charm to pass herself off as his niece, Delphi Diggory, and to ensure he did her bidding.

Despite never knowing either of her parents up close, Delphini inherited many traits from both of them. She was cruel, sadistic, violent, manipulative, dominant, obsessive, and cunning. It can also be said that she was talented and intelligent. However, she had also inherited both her parents' explosive temper, blowing up whenever things didn't go her way.

Rodolphus Lestrange (stepfather)

"You have a prophecy that you must fulfill."

                                                                                   — Rodolphus Lestrange to Delphini as a child in Rowle's home.

Rodolphus was Delphini's stepfather. It is unknown what their relationship was, except that he was the one who paid Rowle to keep Delphi and raise her. After Voldemort's demise, Rodolphus went to prison but possibly escaped and went to Rowle's house, where Delphi was, and told her about her true heritage and prophecy, which she has to fulfill. 

Grandparents:

Merope and Tom Riddle Sr.

"I would like to know my pure-blood grandmother who died giving birth to my father; however, my father hated his Muggle-born father because he was a simple Muggle who left his mother shortly after the love potion effect was gone!"

— Delphini Diggory about her paternal grandparents.

Delphini never knew her paternal grandparents because she wasn't born then. Her paternal grandmother, Merope, died giving birth to her father, and her Muggle grandfather, Tom Riddle Senior, was killed by her own father because he left Merope before Tom was born. Her father killed his paternal grandparents also, and made Morfin (Tom's uncle) do it. 

Druella and Cygnus Black

Also, Delphi never knew or met her maternal grandparents because she wasn't born when they both died.

Aunts/Uncles:

Narcissa and Lucius Malfoy

"How I wished they had kept me."

                                    — Delphi about her aunt Narcissa and uncle Lucius.

Narcissa and Lucius were Delphi's maternal aunt and uncle. They did not raise her for an unknown reason; possibly, she was Voldemort's daughter.

Andromeda and Ted Tonks

Andromeda and Ted were her maternal aunt and uncle. It is unknown whether Andromeda is aware of Delphini's existence or not.

Cousins:

Draco Malfoy

Draco is Delphi's first cousin through her mother's sister, Bellatrix.

Nymphadora Tonks

Nymphadora was Delphini's maternal cousin.
