Personal assistant and "driver" for Cedric Valentine. Max is not only an accomplished driver but also a licensed pilot. He is technically not a Valentine Inc. employee, but his proximity to Mr. Valentine has resulted in him commanding a certain amount of clout in the company.
Max often refers to his current position as "retirement", hinting at a long and complex history of more demanding work. Rumors range from freedom fighter to hitman, special operator to spy. Whatever the case he certainly has never seen fit to offer any clarification to the silent questions on his past. It's unknown how much even Cedric Valentine knows about his assistants past exploits.
