Events of Grand Theft Auto: Chinatown Wars[]
Mann sends Huang Lee an email, warning him that his computer is infected with the "Cow-Worm Virus", suggesting Huang "lift off the PC's outer casing and thrust a cattle-prod into the wiring", and that he should "buy a Fruit Computer, immune to all virus, malware and software that isn't arty".
His name is a play on the term "Mystery Man".
