If it's a deer -character, their speed and agility can be incorporated. In the Naruto world, there are often races or chases. The deer -character could participate in the Chunin Exams' obstacle courses. Their ability to jump high and run fast would give them an edge. Also, deer are known for their calmness. This could be used in battle situations. When facing an enemy, the deer -character could remain calm and use their environment to their advantage, like using the forest as a cover and quickly changing directions to outmaneuver opponents.
If you become a dog in this Naruto fanfiction, your sense of smell can be a huge asset. You could use it to track down missing ninjas. For instance, when Sasuke leaves the village, your dog -character could pick up his scent and follow it. This would create a new sub -plot where you try to convince Sasuke to come back. Your animal ability to smell emotions in a way could also be used. You might be able to sense Sasuke's inner turmoil and use that knowledge to try and reach him on an emotional level.
Let's say you've become a snake. Snakes in Naruto, like Orochimaru's summons, have the ability to move through small spaces and climb easily. Your snake -character could use these abilities to infiltrate enemy hideouts. You could slither through the vents or cracks in a building where the Akatsuki are hiding. Once inside, you can gather intel on their plans. Also, snakes have a certain 'stealth' in their movements which can be used to surprise -attack enemies or avoid being detected by guards.
If you become an animal in this fanfiction, your character could develop new abilities through training. For example, if you're a wolf, you could train to run faster and have better endurance in the wild. You might also learn how to communicate with other animals in the forest, which could be a useful ability for gathering information.
One possible plot could be that Naruto discovers an ancient scroll that has the power to make him sing 'Animal I Have Become'. As he sings, he transforms into a more primal and powerful form, with enhanced speed and strength. He then has to learn to control this new form while also using his singing to defeat a new and dangerous enemy that has emerged in the Hidden Leaf Village.
Well, if you become a dog in this fanfiction, you might be part of a special pack that has a connection to the Inuzuka clan. You could go on missions with them, using your enhanced sense of smell to track down missing nin or valuable items. Or perhaps you become a cat and have the ability to see spirits, like the Nekomata in some legends. This could lead to some interesting interactions with the Hidden Leaf's spiritual side.
Perhaps the character has become a cat. In the Naruto world, cats are often seen as mysterious creatures. The cat -character could have the ability to see chakra in a different way. They notice that there are some strange chakra disturbances in the village that no one else has detected yet. This leads them on a quest to find out what's causing it. Along the way, they team up with Sakura. The cat -character uses their unique perspective and skills, and Sakura uses her medical and combat abilities to solve the mystery and save the village from a hidden danger.
One way could be by having Naruto's ninja skills translate into the GTA 5 world. For example, his ability to run fast and jump high could be like a special ability in the game. He could use his shadow clone jutsu to confuse enemies during heists or missions. Maybe he'd team up with some of the GTA 5 characters and teach them his ninja ways. This would add a whole new dynamic to the GTA 5 gameplay and story.
Animal partners can add a new dimension to the story. They can provide unique abilities that the main character might not have, like the ability to fly or sense things hidden underground. For example, if Naruto had a hawk as a partner, it could help him in scouting areas during missions.
The sharingan ability from Naruto could be integrated into a Gundam x Naruto fanfiction by having a character use it to enhance the Gundam's targeting system. For example, Kakashi could be a Gundam pilot and use his sharingan to quickly analyze enemy movements and weaknesses. The rasengan could also be a part of it. Maybe a character could create a Gundam - sized rasengan as a special attack.
You can start by searching on popular fanfiction websites such as FanFiction.net or Archive of Our Own. Use keywords like 'Naruto', 'girls', and 'animal' in the search bar.
In Naruto fanfiction, a lot of creative animal partners can be found. For example, there could be a magical dolphin that can swim through the air as well as water. It could be used to quickly transport the ninja across long distances. Another idea is a phoenix - like bird that can resurrect from its ashes and provide protection to its partner in the form of a fire shield. And then there's the possibility of a bear with super strength and the intelligence to strategize in battles.
Naruto himself would be the most interesting. Just imagine him, with his energetic and determined personality, now having this strange connection to the song. His singing would be so out of character for him, yet at the same time, it could add a whole new dimension to his character, showing a more artistic and emotional side that we haven't seen much of before.
