DiMA

DiMA is an upcoming character appearing in 2287. He will be the Far Harbor's possible antagonist.

Background
DiMA, along side with Nick Valentine, is one of the only two prototypes the Institute ever manufactured. While DiMA is allowed to freely develop his own personality, Nick is experienced with memory transferring in order for the scientists to see if they can move a living human personality into a synth body. DiMA, feeling remorse and empathy toward Nick, who he regards as his brother because they are the only two of the same unique model, after seeing Nick going through various experiences that cause him to repetitively lose his memory and identity, decide to help Nick escape the Insitute. However, when the two are ounce out, Nick, who is still under the effect of all the things done to him in the lab, start attacking DiMA, forcing him to knock Nick out and left him.Afterward, DiMA come to Far Harbor and, after spend a whole year sitting in a cave doing nothing, decide that it is time for him to venture out the world and define himself. Only after a very long time-about a century- afterward do the two meet again when the Sole Survivor are sent to Far Harbor to investigate on a missing case. DiMA express joy, felling pleased that he is finally reunited with his "brother" again- although the case does not seem to be the same with Nick.

DiMA himself, though initially appears friendly and keeps the people interest at best, have some deep-buried secrets related to the conflict on the island. First, before he set up Acadia, tension between Far Harbor and synth was high. DiMA, desperate to find a way for his people, decide to kill Captain Avery and replace her with a synth-something he show great remorse and guilt about- so he can have a "moderate voice" that able to calm the resident of Far Harbor. Second, he devise a contingency plan to shut down the power source of Far Harbor-which will effectively mass murder all of the resident- in fear of they attacking his synth. Last, he possess the detonate key of the submarine's nuclear missile that, if activated, will destroy the Children of Atom base. All of the three pieces of memory above is locked away from DiMA himself as he cannot bear neither the thought of massive killing nor the guilt over the murder he committed. Unfortunate for DiMA, when the situation of the island worsened, he has to take back those memory again to seek for a truce between the three factions. Base on the player action, DiMA can become an ally or an enemy.
