Well, he'd probably become extremely powerful. With the Infinity Stones' powers, Naruto could potentially control time, space, reality, etc. His already impressive ninjutsu skills combined with the stones' abilities would make him nearly unbeatable. He might be able to create new jutsus that are based on the powers of the stones, like a time - stopping Rasengan or a reality - warping Shadow Clone jutsu.
Well, if Peter Parker uses the Infinity Stones in fanfiction, it really depends on how the writer envisions it. He could accidentally cause chaos. For example, the power of the stones might be too much for him to control at first. But on the other hand, he could use them to enhance his spider - abilities to a whole new level, like being able to travel through different dimensions instantly.
In a fanfiction where Harry Potter has the Infinity Stones, his life would take a completely different turn. First of all, the Space Stone would enable him to teleport anywhere in the wizarding world or even beyond. This would make it impossible for his enemies to catch him. The Soul Stone, on the other hand, might have some deep connection with the wizard's soul. Maybe it could help him understand the true nature of magic and his own destiny better. He could use all these stones' powers in combination to bring about a new era of peace and magic in the wizarding world, but he would also have to face the great temptation and potential corruption that comes with such immense power.
Well, he would probably become extremely powerful. He could use the Time Stone to go back and change certain events in the wizarding world, like preventing some of Voldemort's evil deeds. With the Power Stone, his magical abilities might be amplified to an unimaginable level, allowing him to defeat any dark wizard with ease.
In some fanfictions, if Naruto absorbs the Shinju, he might gain an incredible boost in power. He could potentially have access to vast amounts of chakra, far beyond what he already has. This new power might allow him to easily defeat his enemies, even those who were previously much stronger than him.
If Naruto absorbs Broly in fanfiction, it could lead to some really interesting character developments. Naruto has always been about hard work and friendship, but with Broly's power, he might face new internal struggles. For example, he could struggle with the newfound brute force that might be at odds with his ninja way. Also, his friends might be a bit wary of him at first due to this sudden and extreme power change. But in the end, Naruto would probably find a way to use it for good, just like he always does.
Well, if Naruto absorbs Mizuki in fanfiction, it could be really interesting. Naruto is already quite powerful, but with Mizuki's essence added to him, his power level could skyrocket. He might be able to access new forms of chakra or have enhanced physical abilities. Also, it could create a whole new dynamic in his relationships. His friends might be a bit wary of this new Naruto at first, but then come to accept him as he still has his core self intact.
Well, if Naruto absorbs the shinigami in fanfiction, it's a really wild concept. He could end up with some really strange and powerful abilities. Maybe he could use the shinigami's power to bring back the dead, or he could use it to create some kind of super - jutsu that involves the manipulation of life and death. It could also change his personality, as the power of the shinigami might be a corrupting influence.
In fanfiction, if Naruto absorbs Thanos, he might gain incredible power. Naruto already has his own set of powerful jutsus, and by absorbing Thanos, he could potentially combine Thanos' strength, durability and perhaps his control over the Infinity Stones (if they exist in that fanfic's scenario). He could use this new - found power to protect his village in a whole new way, or even expand his influence to other realms or planets.
If Naruto absorbs Madara in fanfiction, one possible outcome is that he becomes a sort of super - being. His physical abilities would likely skyrocket. He could inherit Madara's battle experience and strategic thinking. Naruto's chakra control might also improve to a new level, allowing him to perform jutsu more efficiently. However, there could be a downside. He might struggle with the darker aspects of Madara's power and memories. It could be a battle within himself to keep his own values while dealing with the influence of Madara's power. And his relationships with his friends and allies might be tested as they try to understand and deal with this new Naruto.
Well, it depends on the source of the Chakra he absorbs. If it's from a powerful and dark entity in the fanfiction, Naruto might struggle with the corrupting influence of that Chakra. He'd have to find a way to purify it or control it, which could be a major part of the story arc. It could also potentially change his personality a bit, making him more brooding or serious as he tries to deal with this new power.
