Power is a common theme. The demonic dragon often represents a great and mysterious power that Naruto or other characters have to deal with. It could be a power they want to obtain, or one that threatens their world.
Another theme is the battle between good and evil. The demonic dragon is usually seen as an evil or at least a dangerous force, and Naruto, as the hero, has to fight against it to protect his friends and the village. But sometimes, the line between good and evil can be blurred, like if the dragon has a tragic past or is being controlled against its will.
Friendship and growth are also themes. Naruto might grow as a person and a ninja through his encounters with the demonic dragon. His friendships with characters like Sakura and Kakashi could be tested and strengthened. And he might make new friends along the way, like a character who has a special connection to the dragon or who helps him in his battle against it.
