Sonic is a popular choice. He and Tails are best friends, so it makes sense for Sonic to show up in Tails' adventure. He could come to Tails' rescue or they could team up to face a common enemy.

Obviously Naruto and the Nine Tails themselves are extremely popular. Naruto is the main character of the original series and his relationship with the Nine Tails is central to the fanfiction. But other characters like Kakashi can also be popular in these fanfictions. Since he is Naruto's teacher, he might be involved in training Naruto when the Nine Tails' influence is changing Naruto's abilities. Also, Sasuke can be a popular character. His rivalry with Naruto can take on new dimensions in Naruto x Nine Tails fanfiction, especially if the Nine Tails' power gives Naruto an edge that Sasuke wants to equal or surpass.

Well, for a 'naruto the nine tailed fox fanfiction', you should definitely consider including Itachi. His actions and his connection to Sasuke can be intertwined with Naruto's story involving the Nine - Tailed Fox. Tsunade is also a popular choice. As the Hokage, she has power and influence over Naruto and any situation regarding the Nine - Tailed Fox. Shikamaru is another character that can be interesting. His intelligence can be used to strategize around the power of the Nine - Tailed Fox. And of course, Gaara.

Sakura could play a role too, perhaps as a healer in case Naruto gets injured during his power - growth process.

Sometimes, other characters from the Naruto universe might also play important roles in these fanfictions. For example, Kakashi could be involved as Naruto's mentor, giving advice on how to better communicate with the Nine - Tails. Or Sakura might be there to support Naruto in his journey of befriending the Nine - Tails, even if she doesn't directly interact with the tailed beast.

Yugito Nii is a very popular character as she is the actual 2 - Tails Jinchuriki in the Naruto series. In fanfiction, she often takes center stage, whether it's in stories about her training or her battles against powerful foes.

A character who is a descendant of an ancient clan that once had a connection to the Nine - Tails could be added. This character could have some knowledge about the Nine - Tails that was lost over time and could help Naruto better understand his power.

Electro is also a popular choice. His electric powers can create some really exciting action scenes. He could be hired by someone to take out either Black Cat or Spiderman, or both. His chaotic nature would make for an interesting dynamic in the fanfiction.
