Angela Cross

A Lombax who masqueraded as a thief for around half of  Going Commando. She sometimes has accidents, like tripping over rugs and whatnot.

Employment
Angela used to work at Megacorp in the Bogon Galaxy in the genetics department. She worked on the original Protopet but quit after Megacorp decided to release the Protopet, even with its flaws.

Thief
She then put on a mask equipped with some kind of voice-distorting device (her voice sounds like a male robot's voice with the mask on) and steals the protopet in hopes of obliterating it before it can be mass-produced. You are asked to get it back because it is very important to Fizzwidget. Ratchet confronts the thief on planet Siberius. He defeats the thief, reclaims the Experiment, and returns it to Mr. Fizzwidget. The thief approaches Ratchet (on his ship), demanding the experiment, not realizing that Ratchet doesn't have it.

Unmasked
When the thief falls off of his ship (falling about 5 feet), his mask comes off, and it's revealed that he is... a she! Angela. She warns Ratchet and Clank that the experiment will ultimately doom the galaxy and joins your team to try and warn Fizzwidget about what they are really capable of. During the adventure, she and Ratchet develop some feelings for one another..
