In this 'naruto becomes god fanfiction', the tailed beasts could be his allies. Since Naruto has a special connection with them, they might see his ascension to godhood as something that could benefit them as well. They could help him by lending their chakra when needed or using their unique abilities in conjunction with Naruto's new god - like powers to face any threats that come their way.
I think Hinata would also be an ally. She has always been in love with Naruto and would support him no matter what. And the rest of the Konoha 11 would probably be his allies too. They have all fought together and have a sense of camaraderie. With Naruto as a god - like figure, they could help him spread his message of peace and use his powers to protect the village and the world at large. They would be the ones who understand Naruto the best and would be there to assist him in any way they can.
In a 'naruto becomes a god fanfic', Naruto's allies could include not only his friends from Konoha but also some unexpected characters. For example, some of the tailed beasts that he has befriended over the years might become his allies in a more direct way. They could combine their powers with Naruto's new god - like abilities to face common threats. And perhaps some of the old ninja clans that have respected Naruto's power and his ideals would also side with him.
He could potentially ally with other characters who also have an interest in the Zerg. Maybe some of his ninja friends who are intrigued by his new form and abilities. Or perhaps he would find unlikely allies among the Zerg themselves, like a group of Zerg that are more peaceful or have a common enemy with Naruto.
Sasuke could be one of his allies. Despite their past differences, Sasuke would recognize the potential of Naruto's new power and the good it could do. Also, Kakashi could be an ally. His wisdom and experience would be valuable in guiding Naruto in this new role. And of course, the other members of the Konoha 11, like Sakura, who would support Naruto in his journey as a god of destruction, believing in his good intentions.
One possible ally could be Poseidon. Naruto's connection to water - based jutsus might make Poseidon interested in him. They could form an alliance where Naruto helps Poseidon in battles using his water techniques in a new and unexpected way, and Poseidon, in return, helps Naruto understand the politics and power dynamics of the Greek god world. Another ally could be the nymphs. These nature spirits might see Naruto as a protector of sorts. Since Naruto has always had a soft spot for nature in his own world, he could bond with the nymphs and they could help him navigate the forests and hidden places of the Greek world, as well as provide him with information about other gods and mortals.
Sakura could be one of his allies. She's intelligent and quick to learn, so she might pick up on the basics of alchemy from Naruto and help him in his alchemical endeavors. She could use her medical knowledge along with alchemy to create new healing techniques.
Sasuke could be one of his allies. Despite their past differences, Sasuke might see Naruto's new path as a way to create a better world. He could offer his combat skills and strategic mind to help Naruto rule. Another ally could be Hinata. She has always been supportive of Naruto, and as emperor, Naruto would need someone he can trust, and Hinata fits that role perfectly.
The local tribes or groups in the West who recognize Naruto's strength and just nature could become his allies. They may see him as a chance for a better future for their land. Also, other ninja from different villages who have a good relationship with Naruto might also lend their support.
Sasuke could be one of his allies. Sasuke's natural combat skills and his sharingan would make him a great asset in aerial battles. He could quickly analyze the enemy's movements and strategies.
Batman would likely be one of his main allies. They both have a strong sense of justice and a determination to protect the city. Their skills are different but complementary. Batman's detective skills and high - tech gadgets combined with Naruto's ninja abilities would make them a great team.
Daryl Dixon could also be an ally. Daryl is a great hunter and tracker. Naruto could learn from Daryl's skills in the new environment, and Daryl could be impressed by Naruto's unique abilities. They could form a strong bond while out on scavenging missions or fighting against large groups of walkers.
