One day, Tigre got involved in a hit-and-run on a car while riding his scooter, injuring the car's driver. Unfortunately for him, the driver, Viola, was the granddaughter of powerful mob boss Bruto Cadaverini. Bruto was furious and demanded from Tigre the $1 million required for the surgery to save Viola's life.

Short on time, Tigre called in all the loans he could. One of his debtors was Elg, who had accumulated a particularly large debt from his gambling addiction on top of Tender Lender's interest rate. Viola, meanwhile, became infatuated with Tigre, unaware of the reason he was paying her medical bills. She began assisting him in his business, to his chargin as he disliked her, but he pretended to appreciate it out of fear of further angering Bruto.

On December 3, Elg met Tigre at the French restaurant Trés Bien, intending to repay the loan by giving him the disc containing MC Bomber, a computer virus that would sell for millions of dollars on the black market. Unfortunately for Tigre, during the meeting, Elg, who was listening to the radio with an earpiece, won the grand prize of the city's local lottery. The prize was enough to pay Elg's debts, but not enough to handle Tigre's. Desperate, Tigre killed Elg by poisoning him and took the disc. He then acted out the murder for the purposes of providing a false witness in Victor Kudo and framing Byrde, who worked at the restaurant; Tigre posed as Elg, while Viola posed as Byrde. Restaurant owner Jean Armstrong, who was indebted to Tigre, was forced to help with the charade. However, Tigre was unaware that the recreation contained a number of mistakes, most notably Elg's earpiece being in the wrong ear.

Tigre then proceeded to disguise himself as the famous defense attorney Phoenix Wright, complete with a cardboard attorney's badge, and offered to defend Byrde in court. Byrde was ultimately taken in by the deception and accepted. Tigre lost the trial against prosecutor Winston Payne, resulting in Byrde's conviction. After the trial, Tigre sold MC Bomber, keeping the original CD of the program for himself, and paid the surgery bill. The virus would later be used to attack the servers of the Criminal Affairs Department.

The following month, the real Wright appealed Byrde's case after hearing about it from Dick Gumshoe. After a first encounter with Wright in which Tigre tried to make him pay for allegedly soiling his scooter, the loan shark quickly retreated upon learning of the latter's identity, flippantly declaring that he himself was "Phoenix Wright". Wright later visited Tender Lender's office, where, after finding evidence of Tigre's deception in court, he once again met face-to-face with Tigre, who once again tried to coerce money out of Wright using the excuse of a soiled carpet. However, Viola's admission of guilt for this particular accident made Tigre relent and leave the scene, but not before threatening Wright to cease trying to ruin his plan.

After speaking with Viola, and making her realize Tigre's true role in her incident, Wright obtained her medical papers. In response, Tigre ambushed Wright at Trés Bien, where he once again forced Armstrong to support him. Tigre roughed up Wright, and was about to burn the medical papers with a lighter, if not for Gumshoe's timely intervention, which allowed Wright to flee with the papers while Gumshoe held off Tigre.

The next day, Wright was able to force Armstrong to confess about his coercion by Tigre, which made the prosecutor, Godot, ask for a recess in order to subpoena him. Despite Tigre's many attempts to dodge accusations, Wright tricked him into implicating himself by presenting a bottle containing Elg's ear medicine and claiming that it was the poison used to kill him; Tigre laughed and made an outburst that corrected him, explaining, in intricate detail, the type of bottle that held the poison, something he would have been unable to do if he was not the killer. Upon realizing his mistake, Tigre screamed, which caused all the lights in the courtroom to break. Viola later implied that she sent poisoned, or at least in some way tainted, tea to him in prison.
