One fanfiction could have a plot twist where the Lumen Sage power is not unique to Naruto. In fact, it was once widespread but was sealed away because it was too dangerous. Naruto's discovery of it reopens old wounds and rivalries among different ninja clans. The story could then explore how Naruto navigates this complex situation with his newfound power.
Sure. There could be a fanfiction where the Lumen Sage power is actually a curse in disguise. Naruto starts using it thinking it's a great power, but then realizes it has some dark side effects that he has to overcome. This would be a huge plot twist as it goes against the usual idea of a new power being only beneficial.
There might be a fanfiction where the Lumen Sage power was created by an ancient enemy of the ninja world. Naruto gets it and everyone initially thinks it's a great asset. But later it's revealed that the power is slowly taking over Naruto's mind and he has to fight against it while also dealing with the real threat behind it. This involves multiple plot twists and keeps the reader on edge.
