RK900 is a character who appears briefly in the video game Detroit: Become Human. It is a later model of the android "Connor" RK800, a main character of the game.

RK900 never speaks in the game. It has an appearance almost identical to the RK800, but with grey eyes instead of brown. It is described as a perfected update to Connor. It presumably has has the same and more abilities as Connor, but little is known definitively. Thus, much fandom activity around RK900 is related to developing headcanons and a widespread fanon characterization.


In fanon RK900 usually portrayed as taller than Connor. His personality is generally far colder and serious than Connor's. He is aggressive, forceful, and/or hyper-competent.

It is usually imagined that after canon RK900 joins the Detroit Police Department and becomes a police android like Connor. Usually he is Gavin Reed's partner.

His relationship with Connor in fanon and fanfiction varies. Their relationship may be distant or they may view each other as brothers. In Human AU works they are generally brothers or twins.

RK900 is referred to by various names by fanon and in fanworks. Fanfiction is likely to explore how he chooses a name. He may choose to go by the "android name" RK900 or, frequently[1], choose a more human/normal name. His names are often based on RK900, such as "Nines" (one of the most popular), RK, names that begin with N or R, names that sound similar to Nine, etc.


RK900 is significantly popular in DBH fandom, disproportionate to his brief appearance in canon. He is the 4th most tagged character in DBH works on AO3. Reed900 is the second most popular DBH ship on AO3, but he also has a large range of characters he's shipped with. His popularity can be attributed to him being essentially a clone of Connor, a DBH protagonist who is extremely popular in canon.


  • Reed900 (Gavin Reed/RK900) - the most popular RK900 ship. The two do not meet in canon. The ship is based on Reed's antagonistic relationship with Connor.
  • RK1700 (Connor/RK900) - a clonecest pairing. Connor and RK900 are also paired together in threesomes.


RK900's popularity is unexpected and confusing to many DBH fans when they first enter the fandom after playing the game, since he never speaks in canon and has no canon characterization. Some fans object to the disproportionate amount of fan content based on him.

It has been suggested that RK900 has become popular only because of erotic fanworks. Criticisms of his popularity are also related to race and gender - some point out that there are characters of color and women with large roles in DBH canon who receive much less attention than RK900. This is related to common criticisms of fanon characterization.
