M.A.R.S, once an abandoned cyborg project of MARS Industries, Dr. MacGregor saw promise in it and took it over. Although there were many failures, he finally succeeded in creating a fully autonomous synthdroid with the ability to think independently and rewrite its own programming. In essence, a living robot with superior intelligence. M.A.R.S has quickly become one of the greatest weapons ever created. Upon seeing M.A.R.S. in action Destro once commented, "MacGregor's creation is by far greater than anything either G.I. Joe or Cobra could ever build."
