If Naruto gets time - manipulation powers, it could make him more cautious. He might be more hesitant to act quickly as he now has the ability to go back and correct mistakes. So, it could change his impulsive nature.
The power to communicate with all living things would make Naruto more empathetic. He would understand the feelings and needs of every living being around him. This would further strengthen his belief in protecting everyone and make him more of a guardian figure in the fanfiction world. He would be more in tune with nature and the cycle of life.
With the power of elemental fusion, Naruto's confidence would soar. He would become more daring in battles, knowing that his attacks are far more potent. This new - found power could also isolate him a bit as others might fear or envy his abilities. But Naruto being Naruto, he would still strive to use this power for the good of the village and his friends.
