Dahlia

Dahlia has dark brown eyes and red hair that is held back by two braids that are tied together. Unlike her twin sister, who is otherwise identical in appearance, her hair is red. She wears a long white dress with pink decals and spaghetti straps, white high heel mules with butterflies on them, a pink scarf around her shoulders, and a white parasol with the same pink decals as her dress. 20 years old.

Dahlia Hawthorne was a student at Ivy University and ex-girlfriend of Phoenix Wright. Although born into the Fey clan, she had little to no known spiritual powers. She appeared as a witness in the murders of her stepsister Valerie Hawthorne, her ex-boyfriend Doug Swallow, and her maternal aunt Misty Fey.

When Dahlia was 14 years old, she got into a relationship with her tutor Terry Fawles. The two made a pact promising to drink poison from a bottle necklace if they ever reached a point where they no longer trusted each other. With the cooperation of her stepsister Valerie, who had become a police detective, Dahlia staged a fake kidnapping plot using Fawles as the "kidnapper" and scapegoat, demanding a $2 million diamond as ransom. Dusky Bridge was arranged to be the exchange spot; owing to its proximity to Hazakura Temple, Dahlia recruited Iris as an accomplice.

During the meeting on the bridge, Valerie and Dahlia began the next part of the plan by betraying Fawles; Valerie shot him in the shoulder, while Dahlia intentionally jumped off the bridge into Eagle River below, taking with her the ransom diamond. Valerie arrested Fawles and falsely testified that he had murdered Dahlia by pushing her off the bridge, leading to the betrayed man's conviction and a sentence on death row. Iris never showed up to assist Dahlia in her plot, as she was too frightened to help. Five years after the "kidnapping" incident, when Fawles was being transferred to another prison, his transport broke down and he escaped. He called Valerie and told her to meet him at Dusky Bridge to explain what had happened during their fake kidnapping plan, as the man had no idea that Dahlia had used and betrayed him. Valerie called Dahlia and told her that she was going to tell the truth about the incident. Fearful of what would result from the meeting, Dahlia stabbed her stepsister at Dusky Bridge, killing her. To establish an alibi for herself, Dahlia took multiple photos of herself in the meadow below the bridge's ledge, using up almost all of the film, before setting the timer for one final photo. When Fawles arrived in a stolen car, Dahlia, while Fawles had gone to retrieve a keepsake that he and Dahlia had buried under a tree at the nearby temple, hid Valerie's corpse in the car's trunk, put on her clothes, and then met Fawles at the bridge while posing as Valerie, which was captured in the final photo. Soon after this meeting, Fawles was recaptured by the police and put on trial for the murder of Valerie Hawthorne. During Fawles's trial, Prosecutor Miles Edgeworth prepared Dahlia as a witness using the Melissa Foster identity. Despite acting the part of a murder witness traumatized by war, Mia Fey, Misty's daughter and the attorney for the defendant, pointed out inconsistencies in her testimony and revealed to the court that "Foster" was Dahlia. Close to the end of the trial, Mia was almost able to prove that Dahlia was Valerie's killer, but Fawles refused to cooperate with Mia, committing suicide instead as per his pact. Mia and Edgeworth would later recall that Dahlia left the courtroom with a "demonic smile on her face".

The result of Terry Fawles's trial drove Mia and her co-worker, defense attorney Diego Armando, to investigate Dahlia. This led to a meeting between Armando and Dahlia in the courthouse cafeteria six months after the trial. Dahlia quietly slipped poison into his coffee from her bottle necklace. The poison had been stolen from Doug Swallow, her boyfriend at the time, who was a pharmacology student at Ivy University. Armando subsequently fell into a coma from the poisoning. Fleeing into the university reading room, Dahlia stumbled across fellow Ivy University student Phoenix Wright and gave him the necklace as a "love gift" to dispose of the evidence, thereby evading the authorities. Swallow later found out about the stolen poison and broke up with her.

Throughout their relationship, Wright had a habit of showing off the bottle necklace to everyone he met, much to Dahlia's displeasure. With Iris having completely failed in her task for eight months, Dahlia suspected that her sister had actually fallen in love with Wright. Without telling her, Dahlia took matters into her own hands and went back to Ivy University herself. She attempted to kill Wright by stealing more of Swallow's poison and using it to poison Wright's cold medicine. Before her plan could come to fruition, Dahlia found Swallow trying to warn Wright about her and the stolen poison. Wright pushed Swallow in a mixture of anger and disbelief, then fled the scene. Dahlia permanently silenced him by using a nearby downed power line to fatally electrocute her former boyfriend.

Dahlia knew that her beauty and innocent appearance threw others off her true nature and took full advantage of it. She had the ability to make herself appear serene and innocent; she would even occasionally have small butterflies flock about her and flutter gently. However, this aura of innocence was a façade, and when pressed into a corner, her demeanor could immediately change to a terrifying, almost demonic visage, which even caused the aforementioned butterflies to burst into flames in some cases. In truth, Dahlia looked after and cared about nobody but herself, and even went as far as to state that this had always been the case for her.

Many who have seen Dahlia's true nature, such as Phoenix Wright and Mia Fey, have described her as a demon, and even the judge has suggested that she never be channeled again. Indeed, all of Dahlia's murders and attempted murders were committed to cover up a previous crime or to exact revenge on Mia Fey. She displayed absolutely no remorse or regret for any of the crimes she had committed, and had no qualms about murdering completely innocent people in the interest of self-preservation or revenge.

Of all the people Phoenix Wright has encountered, Dahlia was among the most dangerous: she was personally involved in seven incidents that resulted in the death or near-death of an individual. Two people were personally murdered by Dahlia herself (Valerie Hawthorne and Doug Swallow), one person was manipulated into committing suicide in her name (Terry Fawles), two people were almost murdered by her in order to conceal her crimes (Phoenix Wright and Diego Armando), one person was almost murdered in an act of revenge against another (Maya Fey in order to get revenge against Mia Fey) and one person was murdered while they were channeling Dahlia (Misty Fey).

Dahlia's sister, Iris, would later reveal a tragic side to Dahlia. Iris described Dahlia as being "strong and smart, never complaining about her situation." Tragically, for all her strength and intelligence, Dahlia was never loved by her parents, and unlike Iris never found a surrogate parental figure. The neglect Dahlia suffered at the hands of their parents, according to Iris, is what eventually led Dahlia to harm so many people, as it embittered Dahlia toward their father, leading to the first of her many crimes.
