Chainsaw Man Fan Theories: Quanxi's Age and Alternate Timelines
Recent fan discussions on the r/Chainsawfolk community explore major lore questions and alternate timelines. Readers are debating how early humanity survived devils before Quanxi became the first devil hunter, while also pitching scenarios where Denji travels back in time or meets Kiga instead of Makima.
Quanxi's True Age and Early Humanity's Survival
A recent fan discussion on r/Chainsawfolk raised questions about the deep history of the Chainsaw Man world, specifically focusing on Quanxi's title as the first devil hunter ever. The post notes that this detail was never elaborated on again, leaving Quanxi's exact age completely unknown.
The theory argues that unless Quanxi is 50k+ years old, humanity should have gone extinct long ago because of devils. The user points out that it is hard to imagine very flammable cavemen using sticks to defeat powerful threats like the Falling and Fire devils.
Alternate Timelines: Time Travel and Kiga's Intervention
Another major topic among fans involves alternate timeline scenarios for Denji. One r/Chainsawfolk post asks what Denji would do differently if he went back in time with all his memories intact, similar to the series Re:Zero. In this scenario, Denji returns to the shackles right before his fight with the Tomato Devil, forcing him to figure out how to handle Makima and process the events of Part 2.
A separate timeline theory wonders what would happen if Kiga found Denji in the alleyway after he killed the Zombie Devil, arriving before Makima does and deciding to take him with her just for fun. Alongside these timeline questions, another fan post jokingly questioned Pochita's past motives, asking why Pochita did not simply hug people instead of killing them if his whole dream was wanting to hug people.
Two sides of the debate
Focus on World-Building and Lore Mysteries
- Quanxi being called the first devil hunter ever was never elaborated on, leaving a major gap in the timeline.
- Unless Quanxi is 50k+ years old, it is difficult to explain how flammable cavemen with sticks survived devils like Falling and Fire without going extinct.
- Fans also debate character logic in the existing lore, such as why Pochita killed people instead of just hugging them if his dream was to hug people.
Focus on Alternate Timeline Scenarios
- Exploring a Re:Zero style scenario where Denji returns to the shackles before the Tomato Devil fight with his memories intact changes the entire story.
- A time-traveling Denji would have to find a completely new way to handle Makima while processing the events of Part 2.
- Having Kiga find Denji in the alleyway after the Zombie Devil fight before Makima arrives creates a completely different path for the protagonist.
