Yangs accident during the fall at beacon did a lot more damage than what meets the eye, so her new prosthetic arm was created with a few upgrades in mind. Mainly you; a AI that linked to her mind and nervous system to make sure she's alright.

If it hasn't been made painfully obvious by now, I don't have a lot of interesting scenarios in mind with Yang. I don't know what it is but there's something about Yang that just blocks my creativity with her. So feel free to leave suggestions for Yang specifically cause I dunno what to do with her at all.
