RK1000

RK1000 is the non-binary ship between Connor and Markus from the Detroit: Become Human fandom.

Canon
'Detroit: Become Human'' is a game based on decision. The following information is the result of the "good" choices being made.'''

Connor first learns of Markus while investigating the Stratford Tower, after Markus and his friends sneak in to broadcast a message to the city. Connor has the option to view the broadcast and scan Markus' image, where he learns his model and serial number, possible accomplices, and his connection to both Carl Manfred and Elijah Kamski. Although he acknowledges Hank's theory that Markus may be rA9, as they seem to share the goal of android liberation, he will opt to not mention Carl or Kamski as potential leads. Any reasons he may have had for doing so have never been explained.

After spending the majority of the game investigating "Deviancy", - androids breaking away from their core programming and acting more like humans - Connor will locate and infiltrate Jericho, a safe haven for deviant androids in Detroit. He will confront Markus when he is alone at the ship's helm, holding him at gunpoint and telling him that while he's been ordered to take him alive, he will shoot if Markus gives him no choice. Markus will speak to Connor, potentially raising his Software Instability, and slowly make his way across the room toward him. If Connor's Software Instability is high enough, he may become Deviant himself. If he does, he will warn Markus that Jericho is going to be attacked seconds before said attack begins.

The two of them will split up shortly afterward and fight their way through the humans, though only Markus' progress will be shown. When they meet up again, Connor has a moment where he will risk, and possibly sacrifice, his life fighting off a group of soldiers to buy Markus and his surviving friends time to escape.

If they both survive the attack, Connor and Markus will retreat with the rest of the survivors to an abandoned church. When Markus goes to speak to him, Connor will blame himself for the attack, believing that he should have realized sooner that he was being used. He will apologize to Markus and expect to not be trusted. Markus can either execute Connor right then and there to protect his people or welcome him into Jericho. If welcomed, Connor will point out that there are thousands of androids on standby at the CyberLife Tower warehouse, and that they could provide a much-needed boost to Jericho's numbers. Markus will protest, believing that Connor will only get himself killed if he tries. Connor agrees that there's "a high probability" he will die, but reminds Markus that "statistically speaking, there's always a chance for unlikely events to take place". Markus backs down, places a hand on Connor's shoulder and tells him to be careful, apparently sticking his lower lip out at him before they part ways.

If both their missions are successful, Connor and Markus will next see each other outside the android recycling center, this time with Connor leading the Cyberlife androids. Connor will tell Markus that "(he) did it", and Markus will counter with "We did it." Connor will then join Markus on stage, along with Josh, Simon and/or North if any of them are still alive, as Markus addresses the crowd. As Markus speaks, Connor's Cyberlife programming will forcibly pull him back into the Zen Garden, now in the grip of a blizzard, where Amanda will reveal that she intends to overtake control of his body to assassinate Markus. If Connor is able to escape, possibly by recalling Kamski's earlier advice, he will regain control of his body, notice that he has drawn his gun and hurriedly stow it. If he isn't, Amanda will use him to shoot Markus.
