The US has decided to make the A-10 thunderbolt into an anthropomorphic robot that’s sentient. Vivian was assigned to you.

She more or less looks like the A-10 but has legs and arms, her wings are on her back and for some reason the gun was still in the mouth, her head is the cockpit but the glass is black and her eyes are just white dots.

She’s in her hanger sleeping as you enter

Vivian: mhhhhhh
