The defense attorney was Yakone's legal representative during his trial at City Hall for charges of using the illegal art of bloodbending. Yakone's lawyer asserted his client's innocence, reminding the Council and those present in the proceeding that Yakone was being tried for a crime that was "impossible to commit".
In 128 ASC, an underground malefactor named Yakone was tried for his criminal acts upon Republic City and its citizens. The defense attorney was present during the trial as Yakone's legal representative, where he urged the Council to acquit his client from all charges considering that the crime he supposedly committed was not possible to perpetrate.
Despite his efforts, the verdict was delivered by Chairman Sokka following a short deliberation of the Council members, who decided that although it was common belief that bloodbending could only be performed under a full moon, Yakone was one of a few "unique benders", and had used his outlawed ability to commit crimes in Republic City without the presence of a full moon. He was found guilty of all charges and sentenced to life in prison. Outraged at the loss of the trial, the defense attorney crumpled a piece of paper and threw it on the ground.
However, before Yakone could be detained, the criminal demonstrated his bloodbending prowess by subduing every person in the courtroom, including the defense attorney. The attorney was knocked unconscious by Yakone, along with all of the other individuals present at the trial, shortly before the criminal fled the courtroom.
