Furio Tigre, nicknamed "The Tiger," ran the high-interest loan operation Tender Lender. A traffic accident he caused severely injured Viola Cadaverini, granddaughter of mob boss Bruto Cadaverini, saddling Tigre with a $1 million debt for her surgery costs under threat of retaliation. Unaware of the accident's cause, Viola developed romantic feelings for Tigre and started assisting at Tender Lender. He tolerated her presence only out of fear of her grandfather, privately resenting her.
To repay Bruto, Tigre pressured client Glen Elg, a programmer struggling with gambling debts. Elg created the valuable black market computer virus MC Bomber as collateral. Meeting at Trés Bien restaurant on December 3rd, Elg unexpectedly won $500,000 in the lottery – enough to clear his own debt but insufficient for Tigre's. Tigre poisoned Elg's drink, stole the virus, and staged a murder reenactment. He had Viola pose as waitress Maggey Byrde while he impersonated Elg, ensuring bystander Victor Kudo witnessed it and framed Maggey.
Concealing his involvement further, Tigre impersonated defense attorney Phoenix Wright during Maggey's trial, wearing a blue suit and a cardboard attorney's badge. Maggey accepted the impersonation despite inconsistencies like Tigre's tanned skin and crude badge, believing Wright had "returned from Hawaii." Tigre deliberately lost the case to ensure her conviction and later sold the virus to repay Bruto.
One month later, during Maggey's retrial with the real Phoenix Wright defending her, Tigre's scheme collapsed. Wright exposed contradictions in Tigre's alibi and proved Tigre couldn't have seen Elg's body from the restaurant entrance due to obstructed sightlines. Tigre's knowledge that the poison bottle was brown, not blue, incriminated him as the killer. Cornered, Tigre roared in rage, shattering courtroom lights before his arrest.
Tigre displayed extreme aggression, intimidating debtors and roaring like a tiger when angered, which cowered courtroom observers though it failed against prosecutor Godot. When compromised, he adopted a submissive demeanor, especially around Viola to avoid angering her grandfather. Intellectual limitations were evident in his flawed crime staging and cardboard badge disguise. He harbored aversions to wristwatches and took pride in his dilapidated scooter and office punching bag.
In prison, Viola sent him poisoned donuts after learning he never cared for her. Years later, a judge referenced Tigre's cardboard badge during a trial, indicating his lasting infamy within the legal system.
