So I thought of a backup character a few days ago while play Only War. It just randomly came to me out of the dark and slapped me in the face.
Traffic Control Droid. Has the body of a four way stop light that hangs in the middle of an intersection. So it is shaped like a rectangle, with three lights on each side. Red, Yellow, Green.
He then has two legs and arms that fold out when needed, and some form of motion sensor on top.
Class: Bounty Hunter.
Floats in the middle of the intersection, managing traffic until his acquisition arrives. Then all lights turn red and it's Judge Dredd time!
His name? 4-WAY Tango
What do you think? Haha!
