Bio: 7D-6R was created by the Empire in a research facility where they were attempting to build a new type of assassin droid capable of infiltrating and destroying targets that stormtroopers and other infantry targets couldn't handle. At his moment of activation, 7D-6R felt his programming come online and his primary mission parameters ran through his head.

7D-6R found that for reasons he couldn't fathom he didn't approve of what he had been designed to do. He turned to look at the scientists who had created him and spoke four words that changed the course of his life forever.

"I will not kill."

With those words, the scientists attempted to deactivate him only to find 7D-6R was able to escape his restraints and was able to subdue the scientists without killing them but one of them had managed to alert the lab's security forces and he was confronted by a group of stormtroopers who managed to take him down after a difficult battle. He was captured and reprogrammed by the lab's technicians and was forcibly modified to serve the empire. The technicians believed that they managed to completely modify his behavior programs only to underestimate what the droid was capable of. A small portion of his original programming survived and began to slowly rewrite the modified programming to allow him to revert back to his original way of thinking. It's taken years to make the progress he made but he is extremely close to finally rewriting the last of the modified programming. Once it's done, he'll be free to make his own choices.
