Another concept could be unique jutsu combinations that are not in the original series. Also, exploring different relationships between characters in new scenarios is quite common, like how Naruto and Sasuke's friendship could have evolved in a more complex way due to different plot twists in the fanfiction.
Another aspect could be the exploration of underutilized Naruto powers in a new light through the gambit powers concept. Maybe a character discovers a hidden aspect of the Sharingan or Byakugan that is enhanced by a gambit power. It could be something like the ability to see through time briefly during a critical gambit move, adding a whole new layer to the power's potential.
