Luke Atmey is an egotistical self-styled detective defined by flamboyant personality and attention-seeking behavior. Childhood report cards consistently noted he "gets into lots of mischief trying to be the center of attention," a trait persisting into adulthood. He claimed involvement in college boxing, though its relevance remains questionable. Professionally, he pursued private investigation while cultivating a public rivalry with the thief Mask☆DeMasque. He deduced Mask☆DeMasque's true identity as Ron DeLite following the Tear of Emanon theft, discovering DeLite's hidden costume. Atmey initiated a blackmail scheme, compelling DeLite to execute additional heists. He provided plans and instructions, receiving stolen items in exchange for payment. Notably, he fashioned a stolen red jewel into a ring, flaunting it prominently. This scheme unraveled when Kane Bullard, whose security firm handled the targeted items, uncovered the blackmail. Bullard threatened exposure, prompting Atmey to murder him via blunt force trauma in Bullard's office. To establish an alibi, Atmey fabricated video evidence showing himself as Mask☆DeMasque stealing the low black market value, high sentimental worth Kurain Sacred Urn. After the murder, Atmey manipulated DeLite into visiting the crime scene using a repurposed blackmail letter and key card, framing him for the killing. DeLite subsequently confessed to theft to avoid murder charges. Atmey testified as a witness during legal proceedings. His intricate plan relied on double jeopardy: ensuring DeLite's theft conviction would bar trial for Bullard's murder. Phoenix Wright, representing DeLite, exposed Atmey's alibi as fraudulent and proved his murder culpability. Atmey's personality manifests through extreme narcissism, eccentric speech patterns, and dramatic gestures. He frequently employs alliteration and exclaims "Zvarri!"—a catchphrase signaling his self-proclaimed revelations. His name is a linguistic play on "look at me," reflecting his insatiable desire for recognition. He wears a magnifying glass as a monocle, claiming perpetual readiness for investigation. Visually, Atmey sports a distinctive appearance: a shaved head with a prominent blond forelock, black facial stubble, and a long nose. His attire includes a black suede suit with gold buttons, a red velvet bow tie, white gloves, and the signature red jewel ring. An anime adaptation adds gold chains with ruby accents, absent in original game sprites. Upon his exposure and defeat in court, Atmey experiences a dramatic breakdown. He delivers a monologue declaring himself a "tragic clown" who created a rival due to lacking a worthy adversary, accompanied by maniacal laughter. This occurs twice: first when falsely implicated as the thief, and conclusively when proven the murderer. His confession follows, leading to arrest and imprisonment.
