STRANGERS are a group of characters and NPCs in OMORI. They serve as mysterious, cryptic entities that occasionally appear before OMORI and his friends in HEADSPACE. Most of them seem to know about the truth regarding the game's overall plot STRANGERS can differ in appearance, but the most prominent sprite set associated with the name STRANGER is one that looks like a silhouette of BASIL. This STRANGER has eerie white pupils and nothing else. Other STRANGERS that appear throughout HEADSPACE occasionally take on the form of people that SUNNY knows from his childhood. These notably consist of AUBREY, KEL, and HERO. A STRANGER with a different sprite can also be found on the TRAIN, bearing similarities to the BASIL sprite with its white pupils and silhouette body but having different hair than BASIL. During the fight with STRANGER on the OMORI ROUTE, he is accompanied by a manifestation of BASIL'S SOMETHING that has the same teeth and tendrils as the one from BASIL's boss battle. Personality-wise, STRANGERS tend to be perceptive and cryptic - they point out to SUNNY about the consequences of his actions alongside passing abstract messages. However, the STRANGER with BASIL's silhouette shows bitterness and aggression toward SUNNY during their battle, citing SUNNY's refusal to face reality as reasonable grounds for trapping SUNNY inside the dream. STRANGER also starts talking from BASIL's point of view during the battle, which implies similarities between STRANGER and BASIL's mindsets. Compared to the real-world BASIL, the STRANGER BASIL displays less anxiety and talks in a manner that is often measured. The STRANGER BASIL is also less prone to be as expressive as BASIL but still shows concern about how the future will play out from SUNNY's actions. There is an implied concern for those living in HEADSPACE since STRANGER asks for mercy on the dream residents. Despite both being somewhat based on real-life BASIL, the STRANGER BASIL considers both dream and real BASIL to be separate entities from itself, referring to BASIL as SUNNY's friend or flower boy instead.
