Dallas Genoard

Dallas Genoard is a young man who, despite the fact that he is an infamous and volatile delinquent, has a loving sister, Eve Genoard, that is one of his few weaknesses. He and his gang initially worked for small time crimes and eventually were pulled into a world of immortals and gang wars bigger than their wildest dreams.

Personality
Dallas is a volatile character who didn't give any care of the world ever since his family squabbled over their fortune and due to his father and brother dying in the hands of the Runorattas, decided to become a crook with his small group of friends. He is known ot be very overprotective of Eve and will become enraged easily if anyone attempts to compromise his sister. He is often distant towards Eve, hating the fact that she relies on miracles and prayers. He prefers action over anything else.

1930 The Rolling Bootlegs
In 1930, Dallas and his cronies were introducted by mugging an old man named Mr. Barnes before being singlehandedly beaten by Camorra capo Firo Prochainezo, after recovering from the severe beating they unknowingly steals two bottles of the Grand Panacea that the immortal Szilard Quates had developed using Barnes. He mistakenly leaves them at the Gandor brothers' hideout after being beat up by Berga Gandor when they were attempting to join the Gandors to get back at Firo Prochainezo, but regardless, Ennis, Szilard's homunculus, apprehends Dallas as he's beating up Isaac and Miria on the street for running into him.

While Dallas is unconscious, Szilard has Ennis inject Dallas and his thugs with the incomplete Panacea, which allows them to be indestructible like the other immortals, but aging continues and will eventually be the death of them. Szilard uses Dallas, who is eager for vengeance against the Gandors and Firo, to steal back the elixir before he plans to devour him. However, while the Gandor brothers are away, Dallas, now cockier than ever with his newfound abilities, shoots up the place after failing to negotiate for the elixir and kills four of the Gandors' men. (In the light novels, Luck mentions them to be some of his closest friends). They successfully steal the elixir and flee the scene with some witnesses catching their description and weapons.

However, with a seemingly uncanny knack for catching the worst luck, Dallas loses the elixir to Isaac and Miria, who thought he was hauling something valuable.

Dallas later awakens with his cronies and corners Firo, Maiza, The Gandors and Ennis. They have a mexican standoff with the gang taking advantage of immortality and shooting them down, they intend to retake the elixir from the party that was welcoming Firo to the Martillo family.

In the end, Dallas, after being hit by a car Issac and Miria stole and were driving and knocked unconscious while they dealt with Szilard Quates. He and his friends later wakes up in an oil drum, captured by the Gandor brothers. Since they were aware of his deathless state, the Gandors decided that the only way they could be rid of Dallas was by cementing him in the barrel and sinking him into the bottom of the Hudson River, condemning him till his death to drown endlessly as punishment for killing The Gandor's men.

1932 Drugs and Dominos
However, in 1932, when Eve, with the help of the Runorata and Gandor families, dredges the river bottom and come up with the drum Dallas was trapped in. But, when they opened it, they realized he wasn't in there, only broken concrete and playing cards remain. The anime does not reveal what happened to Dallas after that, but he is actually kidnapped by Huey Laforet's Lamia. This scene continues on in the Light Novels.

1933 The Slash
Continued from the anime, Eve frantically leaves the shore line after it was revealed that strange people had taken Dallas from his watery prison first.

Dallas awakens paralyzed from his tormented stated after almost three years drowning in the river and met with Huey Laforet's Lamia: Adele and Tim. If Dallas failed to comply, they would use Adele to kill Eve, Dallas swears vengeance against his captives but is forced to work alongside Tim and Adele.

Later, they gather information from the Daily Days on the whereabouts of those immortals and debrief Dallas of 3 years lost. Tim tells Dallas about his status as an incomplete immortal while Adele tells him the basics of Alchemy. Dallas finds the topic redundant and wonders the relevance to his predicament until Tim reminds him that his rivals Firo and Ennis are complete immortals and devoured Szilard Quates, thus stirring some dissent within him that he could be killed by consumption from his two hated enemies yet Firo and Ennis can never be killed by him. Dallas was shortly mocked by Tim with regards to his defective immortality.

Eventually they arrive at the mansion that was owned by his own family much to his chagrin, they confront the current occupants of the mansion consisting of Jacuzzi Splot and his gang with Isaac Dian and Miria Harvent. Tim uses Dallas as a guinea pig as a demonstration of immortality to pay Jacuzzi's gang in order to conduct Huey's experiment. However, Maria later finds delight in maiming and constantly wounding Dallas to the point which Tim orders Adele to stop Maria lest Jacuzzi and his gang is put off from purchasing his price.

Dallas recovers during the climactic confrontation between Adele and Maria with Ronnie forced to intervene. In the scuffle, Nice detonates a smoke bomb and Dallas uses this opportunity to escape. He passes by the Alveare, swearing revenge against Firo and everyon in the mansion.

He later turns over a new leaf and ends up becoming a well-loved philanthropist.
