Some Senku in the Backrooms (Movie) Headcanons I have:
- Senku noclips while gathering resources alone in the wilderness. It happens during a completely mundane task—collecting minerals, surveying terrain, searching for materials, etc. Just like one step, then suddenly he's somewhere else.
- Timeline-wise, Season 2 to VERY early Season 3 works best. Senku has enough scientific knowledge and confidence to actively investigate the Backrooms, but he doesn't yet have access to the Perseus or many advanced technologies.
- The Backrooms manifests as a modern office environment because it is the exact opposite of Senku's reality. Instead of forests, rivers, and primitive villages, he finds fluorescent lights, wallpaper, cubicles, and technology from a world that no longer exists, making it more uncanny..
- Eventually, Senku encounters an entity that looks exactly like him. At first glance it appears normal, but the longer he stares, the more details seem subtly incorrect.
- The entity never attacks, it simply watches.
- Most entities appear to recognize Entity Senku.
- When Entity Senku is nearby, other entities become noticeably cautious. Some immediately retreat and others freeze entirely. Some even take alternate routes to avoid entering the same room.
- After spending enough time near Entity Senku, the other entities begin treating the real Senku differently. In the beginning, they’ll follow him around, some may try to attack while others ‘help.’ But, once this shift occurs, it’s silence from them.
- Radios occasionally pick up voices from the Stone World, but the recordings never respond to him. A lot of them are about him and his disappearance.
