The Hulk got his powers through a gamma radiation accident. Bruce Banner was exposed to a huge dose of gamma rays, and that's what transformed him into the Hulk when he gets angry.
Another way Ichigo could get his powers back in fanfiction is through a magical or spiritual artifact. Maybe he discovers an ancient sword or a talisman that has the ability to restore his lost powers. This could be part of a grander plot where he has to go on a quest to find this item, facing various challenges and enemies along the way. During this journey, he might also learn more about the true nature of his powers and how they are connected to the overall 'Bleach' universe.
One unique way in fanfiction is that he gets his powers from a virtual reality experiment. The scientists were trying to simulate the powers of a spider in a digital realm, but something went wrong and Peter Parker, who was a test subject, got the powers transferred to him in the real world.
In a Fairy Tail fanfiction, the Hulk's powers would likely cause quite a stir. His raw strength is his most notable power. In the Fairy Tail universe, this could make him a feared or respected figure. If he were to join the Fairy Tail guild, his way of fighting would be very different from the mages. He doesn't rely on incantations or magical spells. Instead, he just uses his fists. This could inspire some of the younger mages to think about different ways of fighting. Also, his power that grows with anger could be seen as a sort of uncontrollable magic. The guild might have to find a way to help him manage his anger so that he doesn't go on a rampage and cause destruction to the guild or its surroundings.

One way could be through a magical encounter. Maybe he stumbles upon an ancient artifact that has the power to restore his abilities. It could be a relic from his home planet that he discovers by chance.
His powers would change a great deal. Naruto is known for his brute strength and his ability to never give up. The Sharingan would add a whole new layer of finesse to his fighting style. He could use the Sharingan's genjutsu capabilities to trap his enemies in illusions before hitting them with a powerful chakra - infused punch. Also, he could use it to analyze his opponents' weaknesses more quickly, allowing him to adapt his fighting strategy on the fly.
His relationship with Sakura might change. Sakura would be even more impressed with Naruto having this new power. She might see him as an even greater ninja and could potentially develop stronger feelings for him. Naruto, on the other hand, might use his telekinesis to do small things for Sakura, like picking flowers for her without having to touch them.
