His ability to sense danger could remain. Just like in the Naruto series where he could sense approaching threats, as Ruby's pet, he could alert her to any oncoming Grimm or enemies. This would give Ruby and her team an edge in battles and during their travels in the dangerous world of RWBY.
He might still have his enhanced physical abilities. Even as a pet, Naruto could be super strong and fast. This would be useful for Ruby in a lot of ways. For instance, if they were in a dangerous situation, Naruto could use his speed to escape or his strength to protect Ruby.
Naruto could potentially still use some of his chakra - based abilities in a modified form. Maybe he could use his chakra to create small illusions to distract enemies. Since RWBY has its own set of rules regarding magic and powers, these chakra abilities might be tweaked to fit into the RWBY universe.
Yes, in some RWBY fanfictions, Naruto can be depicted as Ruby's pet. Fanfiction allows for creative crossovers like this where characters from different universes interact in unique ways.
In the fanfiction, Ruby as a demon may have the power of flight. Many demons in fictional works have wings or the ability to levitate. This would give her an edge in battles, allowing her to quickly move around the battlefield. Additionally, she could have the power of regeneration. Demons are sometimes shown as being able to heal from wounds quickly, and this new Ruby might be able to do the same, making her a more formidable opponent.
One possible storyline could be Naruto using his ninja skills to protect Ruby from the Grimm. His ability to move stealthily and use jutsus could give Ruby an edge in combat.
In the realm of RWBY fanfiction, the possibilities are endless. It's not unheard of for Harry Potter to be Ruby's pet. This could potentially lead to some hilarious scenarios. For example, Ruby might take Harry Potter (in his pet form) on her adventures in the RWBY world. He could use his magic in unexpected ways to help Ruby and her team out of tough situations, or maybe just cause some chaos in the process. The idea combines the magic and mystery of the Harry Potter series with the action - packed world of RWBY in a really novel way.
He could have a summon - like animal as a pet. For example, a toad that he befriends and keeps as a pet instead of just using for summons in battles.
It could make Ruby more confident. Naruto is a character known for his never - give - up attitude. By having him as a pet, Ruby might be inspired by this. When facing difficult situations in her RWBY world, like tough battles or complex problems, she could draw on Naruto's spirit. His presence could be a constant reminder to keep pushing forward, and this would contribute to her growth as a character.
He could have similar powers to Ruby. Maybe his semblance is also related to speed, but with a different twist. For instance, while Ruby can move super fast, Si could be able to speed up time around him for a short period.
It could have super speed, allowing it to quickly dash across the battlefield and catch enemies off - guard.
One possibility is that the child has a unique form of sensory perception. Naruto has his own way of sensing things, and Koyuki might have some hidden senses related to her royal heritage. Combined, the child could have a super - sense that allows it to detect not only chakra but also other hidden energies or threats. Also, the child could have the ability to communicate with animals, a trait that could come from Naruto's connection to the toads and Koyuki's possible connection to the local fauna in her land.
It could be about Harry having unique abilities as Ruby's pet. Maybe he can sense Grimm before they appear, helping Ruby in her battles. He might also have a special bond with Ruby that allows them to communicate in a non - verbal way.
