Giovanni Luchese was an Italian-American mobster under the employ of the kingpin, Black Mask as well as his body double. He appeared as a minor character in Arkham Origins.
Details on Giovanni's life prior to working under Roman Sionis were unknown, although Batman's investigation into GCPD records states he underwent outstanding warrants of assault and assault with a deadly weapon. At some point, he joined Black Mask's Gang where he rised the ranks and became one of Black Mask's most trusted lieutenants, serving most of the time as Black Mask's bodyguard and body double.
Before Arkham Origins
After a new criminal mastermind known as the Joker managed to break into one of Roman Sionis/Black Mask's safehouses at Lacey Towers, and abduct Sionis' girlfriend, Tiffany Ambrose, Roman Sionis, who was afflicted with paranoia, had Giovanni, one of his trusted henchmen, pose as Black Mask to distract the Joker while Sionis himself ambushed him from a window behind him. Unfortunately for Giovanni, the Joker had already deduced that he was not actually Sionis (whom he needed alive so that he could steal laundered money from the Gotham Merchant's Bank, since it had safeguards that only Sionis himself could bypass), and managed to kill him instantly by shooting him straight through the heart. Giovanni was 31 at the time of his death.
Events of Arkham Origins
Luchese's body was later found by the Penguin when he was investigating the incident. The Penguin was able to deduce that it was not Black Mask, as Luchese did not have a pacemaker. When the GCPD found his body, they overlooked that, as well as that Sionis had installed security features at the Gotham Merchant's Bank that only he was able to disable, assumed that it was Sionis' body instead, and that he was murdered by the Penguin (due to the latter leaving fingerprints at the scene, and also overlooked the handprint on the soot meant that he had arrived days later).
- Giovanni Luchese was never actually named during the initial investigation on the Lacey Towers murder. He was instead named during Batman's summation of what actually happened shortly after he hacking into the National Criminal Database lines in the sewers. More specifically, he was named in the text accompanying the summation.
- Giovanni's mask was different from the other mobster's masks.
