Thorwall

Thorwall is a Combat SecUnit that after various software and hardware malfunctions was supposed to be scrapped, but then a group of pirates stole it from the disassembly facility and turned it on. Turns out, one of the malfunctioning software parts was Thorwall's governor module, rendering it a rogue. Ironically, Thorwall chose part of the name of the station where it was to be disassembled as its name (HillThorWallImd).
Faced with the option to either a) get destroyed by the company it belonged to or b) go with pirates and live as a rogue construct it decided to rather become a pirate. 

Thorwall doesn't mind shooting shit if shit needs to be shot so this was a rather easy decision.

Since there's no repair cubicles on pirate ships, Thorwall trained the young boy it meets there as its maintenance technician. It's not ideal but it makes fast friends with Lark (another OC I also added on AF) and decided that he is its human now. They know each other for about 10 years before they decide to finally leave the pirate life behind...

Thorwall loves ping-pong, taking care of its human and children.
