His new powers might make some of his friends a bit wary at first. They could be worried that he's changing too much. But as they see him use his powers for good, they'll likely become more accepting. His enemies, on the other hand, will be more afraid of him and might target him even more.
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.
Perhaps he gets a power related to mind control. This would allow him to influence the actions of his enemies or even make them fight among themselves. He could also gain a power that lets him absorb the powers of his defeated foes. So, every time he defeats an enemy, he becomes stronger by adding their powers to his own arsenal.
One possible fanfic could be where Ichigo discovers new and enhanced Quincy powers that he didn't know he had. He might struggle to control them at first, causing some chaos in the Soul Society. But as he trains and learns more about his Quincy heritage, he becomes a more formidable force against the Hollows and other threats.
Their powers could be combined in a way where Ichigo's Zanpakuto spirit, Zangetsu, and Halibel's water - based powers merge. For example, Ichigo could gain the ability to use water - enhanced slashes that have the cutting power of his normal attacks along with the fluidity of Halibel's water attacks.
The plot could involve Ichigo discovering he has gamer powers. Maybe he can level up his combat skills like in a game, which gives him an edge in battles against Hollows. He might also gain access to in - game items that have real - world applications in his fight to protect the Soul Society.
Ichigo's Soul Reaper powers are based on spiritual energy, and Korra's bending is based on her connection to the elements. Their powers could interact in a way that creates a new form of energy. For example, when Ichigo uses his Getsuga Tenshou near Korra while she's bending, it might create a shockwave that combines the force of the spiritual energy blast with the element she's bending. This could be a very powerful and unique combination that they could use to defeat enemies.
Their powers could combine in a really cool way. Ichigo's Bankai could be enhanced by Naruto's chakra. For example, Ichigo's Getsuga Tensho might be infused with Naruto's Rasengan energy, creating a super - powerful attack that has both the slashing force of the Getsuga Tensho and the explosive power of the Rasengan. Or Naruto could use his Shadow Clone Jutsu and have each clone hold a bit of Ichigo's reiatsu, allowing them to perform small - scale Soul Reaper attacks while Naruto himself focuses on a large - scale jutsu combined with Ichigo's power.
In certain fanfictions, a magical or spiritual artifact plays a crucial role in Ichigo getting his powers back. This artifact might be something that has a deep connection to his past or his family heritage. It could bestow upon him the energy or the knowledge needed to regain his powers. Maybe it was hidden away for a long time, waiting for the right moment to be discovered by Ichigo.
