M1-4X, also known as a M1-4X Advanced War Droid or colloquially as Forex, was a unique assault droid built by Doctor Boab Deduun of the Galactic Republic. Initially developed under Project Ignition with a production cost of 15 million credits, Forex was abandoned due to the complications with its power core but secretly completed by Deduun with the patronage of Harron Tavus.
