10 Jaw-Dropping Masked Villain Reveals In Video Games
3. Unknown Thief - Ratchet & Clank: Going Commando (2003)
Transported to the Bogon galaxy, the celebrity heroes Ratchet and Clank are tasked by the CEO of Megacorp, Abercrombie Fizzwidget, with hunting down a prototype lab specimen that was stolen by a shifty masked character.
Working with the Thugs-4-Less company, the thief is hellbent on taking down Megacorp, and doesn't think twice about going beyond simple theft to do so. Ratchet and Clank corner him on the planet Tabora, and when he trips during his grand speech, his mask and cloak fall off. The thief is no 'he' after all; she's a 'she'!
Not only that, but she's a Lombax, just like Ratchet. Revealing herself as Angela Cross, a former Megacorp employee who wasn't given enough time to perfect the company's new product, the Protopet, she explains that the creatures are extremely dangerous in their current form and must be stopped before Megacorp ships them out all over the galaxy.
The twist here, then, is that the Unknown Thief was really the good guy all along - which you'd admittedly have a hard time predicting since she shoots the living daylights out of you until this point.
