Razorbacks are Automatons that can be summoned using the DAEMON's Darknet, normally used only for short periods of time by mid level agents of the Darknet.
The razorbacks can be defined by high-power motorcycles covered in razor-blades and katanas, those are used as weapons. They can run on fossil fuels or batteries, while using betteries they are very silent, but razorbacks cannot run like this for very long.
There are also versions of the razorback with hydraulic kickstands and plasma torches, used to breach safe rooms, among other things.Edit
They are one of the favorite weapons of the Darknet Agent Loki, who uses a pack of his own personal razorbacks, this only being possible for a high level agent to maintain.
