Perhaps they can create illusions. Ravens are often associated with mystery, and in fanfiction, they could use this to deceive Naruto's enemies. They might be able to make large - scale illusions that can confuse entire armies.
They could have the ability to fly at extremely high speeds. This would be useful for quick getaways or surprise attacks.
The plot could be that Raven is in a dire situation in her world. She discovers an ancient spell that might be able to bring a powerful ally to her side. She decides to use it to summon Naruto. Once Naruto arrives, they face a powerful enemy that is threatening Raven's world. They combine their powers, Naruto's Rasengan and Raven's dark magic, to defeat the enemy.
A possible plotline is that the scarab is actually a guardian of a secret ninja art. Naruto has to prove himself worthy to the scarab in order to learn this art. Along the way, he faces many challenges and battles, but with the help of his friends, he manages to earn the scarab's trust and gain the new power.
One possible origin could be a secret scroll he finds. Maybe it was hidden by an ancient shinobi who had the power to summon ravens, and Naruto stumbles upon it during one of his adventures.
In this fanfiction, Naruto could potentially develop the ability to create dark energy constructs like Raven does. For example, he could form weapons out of this energy, giving him an extra edge in close - combat situations. He may also inherit Raven's power of flight, which would completely change his mobility in battles and how he approaches combat scenarios. Additionally, Naruto could gain the power to absorb and redistribute energy, which could be used to either heal himself or boost his attacks. This new set of abilities would not only make Naruto more powerful but also open up new storylines and character developments within the fanfiction.
Naruto's Rasengan combined with Raven's weapon skills could be really cool. For example, Raven could use her sword to enhance the power and direction of Naruto's Rasengan, creating a more devastating attack.
Perhaps Raven loves Naruto fanfiction because it offers a sense of escapism. The Naruto world is a place full of adventure, magic (in the form of chakra), and heroic deeds. Reading fanfiction allows Raven to immerse herself in this world and forget about the real - world problems for a while. Additionally, the community around Naruto fanfiction can be very engaging, with people sharing their own ideas and interpretations, which could also be a draw for Raven.
One common ability is intelligence - gathering. The raven can fly unnoticed and spy on enemies, then report back to Naruto. Another ability could be illusion - casting. It can create illusions in the minds of the opponents, making them see things that aren't there or misjudge Naruto's movements. It might also have the power of wind manipulation, using its wings to generate strong gusts of wind to either attack or defend.
There could be many interesting fanfictions on Naruto's Scarab Summons. Maybe in one, the scarab summons could have unique powers like being able to dig through any terrain super fast, allowing Naruto to use it for quick escapes or surprise attacks during battles.
One possible ability of the Ranton bloodline in fanfiction could be the creation of water - based illusions. These illusions would be more effective near water sources. Another ability might be the power to instantly freeze any liquid they come into contact with, which could be used both defensively and offensively.
Beetle summons in Naruto fanfiction could also possess the ability to manipulate earth. Their strong exoskeletons could be related to an affinity for earth - based jutsu, allowing them to tunnel through the ground quickly and emerge unexpectedly during combat.
