- "Aren't you a blast of air from the bellows?"
- ―Petra, meeting Aloy
Petra is an Oseram inventor from the settlement of Free Heap. When she and her people came across some valuable machine parts, a clan of bandits and some Scrappers stole much of their goods and tried to take their claim. Petra hires Aloy to take back the goods, which provokes the bandits to commit a full-scale assault on Free Heap.
Fortunately, Petra uses the recovered parts to complete her prototype Oseram Cannon, which Aloy uses to lay waste to the bandits, saving the claim and gaining Petra's gratitude.
Later, Aloy and Petra meet again after Aloy obtains some Behemoth cables for her.
Petra is slightly shorter than Aloy, with very tanned skin and short, dark hair under a brown bandana. She wears a plain white top under a heavy studded leather apron with shoulder pads and gauntlets.
Petra is confident and easygoing. She speaks playfully and is quite friendly to her allies, though can be hotheaded and has a famously bad temper.
It is hinted that Petra was attracted to Aloy, as she makes several remarks to her that included innuendos, and even stated that she had a weakness for restless girls. Her banter prompts Aloy to ask if all Oseram flirt at inopportune moments.
Petra is highly skilled craftswoman and inventor, creating advanced devices like the Oseram Cannon, the most powerful weapon in the game.
