Based on the Proxy Character and universe by Pizzacat.
PBG here is supposed to be a military grade support unit. She is loaded with all kinds of vehicles, attachments and gear and you never know what she's going to deploy next.
The concept is still in progress, her current design screams of HALO > Spartan > Mjolnir armor, which isn't a bad thing per se but I'd like to see about developing a sexier helmet+armor.
