The Still Lifes are the creation of the Backrooms attempting to sequence humans and copy them into the Complex. This differs from the widely accepted origin of the Lifeform, which is presumed to originate from a mutated strand of simple hay bacillus. However, their unpredictable nature is still reminiscent of that of the Lifeform, as it pursues its victims on sight and makes loud, disturbing noises once it catches up to them. Additionally, it is likely that they establish dens within the Backrooms where they usually gather things they discover or people they kill.
