Freak Masterstroke is a snide, fast-talking venture capitalist. He has a thin moustache and dark hair which is grey at the temples.

Masterstroke contacted Moon 13 during Experiment #1106 - Starcrash. Kinga and Max attempted to convince Masterstroke to invest in some of their projects, but Masterstroke found flaws in all of them. Unimpressed, Masterstroke departed abruptly.
