If Harry Potter was raised by Maito Gai, his personality would likely be much more exuberant. Gai's positive and energetic nature would rub off on Harry. Harry might be more openly confident and enthusiastic about facing challenges, rather than the sometimes hesitant boy we see in the original series. He could also have a stronger sense of camaraderie, inspired by Gai's bond with his friends and students.
One new ability could be enhanced focus. Maito Gai emphasizes concentration in his training. Harry, under his care, would be able to better focus his magic, making it more powerful and accurate. He might also develop the ability to sense danger more acutely. Gai's own perceptiveness and battle - hardened instincts could transfer to Harry. And Harry's magical stamina could improve because of the physical conditioning he'd get from Gai - inspired workouts, allowing him to cast more spells without tiring easily.
Sasuke is often a popular character in these fanfictions. He might play a role in helping Naruto against Madara or have his own motives during their battle. Kakashi can also be a prominent figure, perhaps using his Sharingan in a crucial moment to assist Naruto. Another popular character could be Hashirama, as his connection to Madara is a key part of the original story and can be further explored in fanfiction.
One interesting plotline could be Naruto discovers a new form that gives him an edge over Madara. For example, a form that allows him to nullify Madara's Sharingan abilities. Another could be Madara having a change of heart due to Naruto's unwavering belief in him. Maybe he starts to question his own motives for destruction.
There's not enough information to determine exactly who Gai is. It could be a fan, a self - appointed protector within the fanfiction community, or perhaps someone with a personal connection to the Sakura concept in the fanfiction.
In such a fanfiction, Naruto and Sasuke might win. They are both extremely powerful and their combined strength, like Naruto's Rasengan and Sasuke's Chidori, could overpower Madara.
In this kind of fanfiction, Naruto being 'godlike' gives him a huge advantage. He might have powers far beyond his normal capabilities. So, Naruto would likely win. He could use his super - enhanced Sage Mode, or maybe some new jutsu that he has acquired in this 'godlike' state to overpower Madara.
Well, the 'transmigration maito maid web novel' might revolve around a maid's story in a transmigrated world. It could be that the maid has some special abilities or knowledge from her previous life that she uses in this new world. For example, she might use her modern - day knowledge to improve the household she works in, or she could be involved in some sort of mystery or intrigue related to the new world she has entered.
Maybe it's an existing minor character from the Harry Potter universe who is given a new identity and role as 'gai'. For example, a little - known wizard who has been living in seclusion but has some extraordinary abilities and decides to take Harry under his wing.
