In this fanfiction, potential allies could include certain Daedric Princes. For example, Hermaeus Mora might be interested in the knowledge that the Dragon Priest - Dragonborn could gain during his adventures. However, the enemies list is long. The cultists of Alduin could be against him as he would be a direct threat to their plans to resurrect Alduin. Also, some of the more traditionalist mages in the College of Winterhold might be suspicious of his powers, fearing he could bring chaos to the magical balance in Skyrim.
Potential allies could be the Greybeards. They are known for guiding the Dragonborn, and if they recognize the Dragon Priest as the new Dragonborn, they might offer their wisdom and support. Enemies could be the Thalmor. They often oppose powerful individuals who could disrupt their plans, and a Dragon Priest - turned - Dragonborn would be a huge threat to them.
The plot could involve the Dragon Priest, who is typically an antagonist in Skyrim, discovering that he is the Dragonborn. Maybe he would initially struggle with this new identity, as his former role was to oppose the Dragonborn. He could then face moral dilemmas about his past actions and his new destiny.
Potential allies could be his friends like Sasuke. Sasuke, with his sharingan and combat skills, could team up with Naruto in battles against those who fear Naruto's newfound genjutsu power. Enemies might include Orochimaru. Orochimaru is always interested in powerful abilities and would likely see Naruto as a threat to his plans.
The Ents could be an interesting potential ally. Their connection to nature and their power could be something that Sylvanas would want to harness for her own ends. On the other hand, the Uruk - hai, with their brute strength and loyalty to the dark forces, would almost certainly be enemies. Their chaotic and violent nature would be in direct opposition to whatever plans Sylvanas has in the fanfiction.
Allies would definitely include Naruto's closest friends like Sasuke and Sakura. They would stand by him even with his new identity. From the Dragon Ball world, Goku could be an ally as he has a good relationship with Beerus. Enemies could be those who want to use Naruto's connection to Beerus for their own evil purposes. For example, some rogue ninja groups might try to capture Naruto to bargain with Beerus. Also, any new villains introduced in the fanfiction who are jealous of Naruto's power would be his enemies.
For allies, All Might could be an interesting choice even when they are babies. All Might might sense Izuku's potential and also see that Shigaraki could be redeemed if guided right. Another potential ally could be Aizawa. He could be the one who trains them in basic self - defense skills when they are kids. As for enemies, the League of Villains could be a problem for Izuku, as they might see him as a threat to their plans with Shigaraki. Also, some of the more evil - minded heroes who don't believe in second chances for villains like Shigaraki could be enemies.
Allies could include his usual friends like Sasuke and Sakura. Since Naruto has the connection to All Might, they might see him as an even greater leader and support him more strongly. Kakashi could also be an important ally, guiding Naruto on how to combine his newfound 'All Might - like' qualities with his ninja skills. As for enemies, Orochimaru might be interested in Naruto's new power source and try to steal it for his own evil purposes. The Akatsuki could also view Naruto as a major threat now that he has additional power and try to eliminate him.
His friends like Brock and Misty could be his allies. They might help him with information about shiny Pokémon locations or offer support during his hunts. As for enemies, there could be some rival shiny hunters who don't want Ash to get the shinies they are also targeting.
His Pokemon could be his potential allies. They've been with him through thick and thin and would likely still support him even with his new vampire state. As for enemies, there might be those in the Pokemon world who fear or dislike vampires and would see Ash as a threat. Maybe some powerful and evil Pokemon trainers who want to use his new situation against him.
When Madara travels through time, he might find allies in unexpected places. For instance, some of the minor ninja clans that were oppressed by the larger clans in the past could see Madara as a liberator if he offers them a better future. On the other hand, those who benefit from the current ninja world order, such as the Daimyo or certain powerful shinobi from other villages, might see Madara as a threat and become his enemies.
As for enemies, Percy could encounter the Titans who were once banished there. They might see Percy as an intruder and a threat, and try to eliminate him. Also, the monstrous creatures that lurk in Tartarus, like the Empousai or the Chimera, could be his foes.
