Kristoph's younger brother, a prosecutor, as well as lead vocalist and lead guitar for the rock band the Gavinners, made up of various people in law enforcement. In a stark contrast to the series' previous prosecutors, Klavier, despite being a perfectionist, does not strive for maintaining a perfect record in the courtroom, instead making sure that justice is duly served by working with the defense attorneys to achieve the proper verdict. Unlike the previous prosecutors from the series, who usually displayed outright contempt for Phoenix, he is quite civil to Apollo when they run into each other. Despite this, he nicknames Apollo "Herr Forehead" (in reference to a contradiction Apollo pointed out in court, as well as Apollo's forehead being quite prominent). He studied law in Germany, like Franziska von Karma, and often uses bits of German vocabulary in his speech. His name is derived from the German word "klavier", meaning piano. His style of dress reflects his rock star personality; the collar of his shirt is left open and he wears a chain-link belt and a large necklace bearing his last initial. He claims he wishes to keep himself simple, because the rest of the world is complicated. At the end of Apollo Justice: Ace Attorney, Klavier disbanded the Gavinners after their rhythm guitarist was convicted of murdering an Interpol agent. In the 3rd case of Ace Attorney Investigations, the Gavinner's logo appears in the stadium's stage. He often tries to tease his employee, Ema Skye, who calls him a "glimmerous fop".

His weapon is a ludicrously over-sized nodachi. Despite its length, he can use it one-handed.
