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. 

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 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."

                                    — Dephini 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.
