Naruto's chakra - based powers and Raven's magic - based powers could have some really interesting interactions. For example, Naruto's Rasengan, which is a concentrated form of chakra, might be able to disrupt Raven's dark energy constructs if it comes into contact with them. On the other hand, Raven's magic could potentially be used to manipulate Naruto's chakra flow, either enhancing it or blocking it. If Naruto were to create shadow clones, Raven could use her telekinesis to move them around in ways Naruto might not have thought of, creating new combat strategies.
Imagine Naruto using his chakra to enhance Raven's teleportation ability. His chakra could act as a booster, allowing her to travel greater distances or even between dimensions more easily. Raven's ability to sense emotions with her magic could also be useful when Naruto is in his Nine - Tails - influenced state. She could use her magic to soothe the Nine - Tails' rage, allowing Naruto to regain control more quickly. And when Raven summons her dark entities, Naruto could use his ninja skills to fight alongside them more effectively, perhaps using his speed and agility to complement their brute force. Their powers could blend in a way that makes them a formidable duo against any foe.
Naruto's power of the Nine - Tails could be a major factor in their power interactions. The Nine - Tails' chakra is extremely powerful and chaotic. Raven, with her control over her own inner demons, might be able to help Naruto better control the Nine - Tails' power. In return, Naruto's vast chakra reserves could amplify Raven's magic. When Naruto uses his Sage Mode, his connection to nature could interact with Raven's connection to the otherworldly forces in her magic. They could combine their powers to create something entirely new, like a chakra - infused dark energy shield or a magic - enhanced Rasengan.
