However after Project Damocles a project he initiated was mothballed he was discharged, after that he went rogue and adopted the codename Silas and formed MECH, an organization bent on enforcing a newer world order. This would involve obtaining weapons of mass destruction. Upon learning of the Transformers' existence, he then decided to accomplish his mission by obtaining their components for his project to create MECH's own Transformers regardless of their affiliation. Silas is willing to go to any lengths to see this mission though, even teaming up with the cons or trying to get innocent people killed.
