The baby could inherit Naruto's chakra - based powers. It might be able to use techniques like the Rasengan or Shadow Clone Jutsu. From Ruby Rose, it could inherit the ability to use Dust and perhaps have a semblance related to speed or agility, similar to Ruby's own. Maybe it could even combine these powers, like using chakra to enhance the effectiveness of Dust - based attacks.
Well, Naruto's world has a strong ninja culture with values like loyalty and hard work. Ruby Rose is from a more technologically advanced world with a focus on combat against the Grimm. In the upbringing of their baby, they might combine Naruto's physical training regime with Ruby's use of high - tech weapons. For example, the baby could be trained to use a kunai in one hand and a high - tech pistol in the other. They would also have to blend the moral values of both worlds. Naruto's sense of protecting the village and friends could be paired with Ruby's sense of duty to protect humanity from the Grimm.
I'm not sure if there is such a specific fanfic. Fanfics cover a vast range of ideas, but this cross - over concept might be quite rare. It would involve combining the universes of RWBY and Naruto in a rather unique way. You could try searching on major fanfic platforms like Archive of Our Own or Fanfiction.net to see if it exists.
The baby could be an orphan from a war - torn area that Ruby Rose discovers. It might have no known family, and Ruby's discovery of the baby could be a turning point for her character, making her more empathetic towards the plight of the innocent in such situations.
It really depends on the context. In terms of raw physical strength, Naruto has his super - powered ninja skills and access to the Nine - Tails' chakra which gives him incredible power. However, Ruby Rose has her speed and agility along with her powerful scythe, Crescent Rose. If it's a long - distance battle, Ruby might have the upper hand with her ranged attacks using Crescent Rose. But in close - combat, Naruto's hand - to - hand combat skills and ninjutsu could be dominant.
One common theme could be power. Since Naruto is 'godlike', the story might revolve around his extraordinary powers and how they interact with Ruby Rose's abilities from RWBY. Another theme could be relationships, as it's a harem - type fanfic, so there will be multiple relationship dynamics between Naruto and other characters.
There's a fanfic called 'Ruby's New Adventure' which takes Ruby on a journey through different dimensions. This fanfic is full of action and also has some great character interactions. It shows Ruby in a whole new light, facing challenges she's never encountered before. The author does a wonderful job of creating vivid descriptions of the different dimensions.
One possible plot could be that Ruby Rose stumbles upon a baby in a dangerous or strange situation. Maybe she's on a mission and finds the baby in an abandoned building. She then decides to take the baby under her wing, protecting it from any threats that come their way.
It would be a very strange and interesting mix. Ruby Rose is a scythe - wielding huntress with a focus on Grimm - slaying in a world filled with magic and unique technology. Naruto, on the other hand, is a ninja with a strong will and the ability to use chakra. In the fanfic, they might start off as strangers from different worlds who somehow cross paths. Maybe Ruby gets transported to the Naruto universe and is intrigued by Naruto's determination. Their relationship could grow as they learn from each other, with Ruby showing Naruto some of her combat skills and Naruto teaching her about chakra.
One great RWBY Ruby Rose fanfic is 'The Rose That Bloomed in the Dark'. It explores Ruby's character in a post - apocalyptic Remnant. Another interesting one is 'Ruby's Ascent', which focuses on her growth as a huntress. And 'A Ruby's Tale' is also good as it shows different aspects of Ruby's relationships with her team.
