As a god, he would have incredible powers, so he could easily defeat Voldemort much earlier and save a lot of lives. Maybe he would also use his newfound god - like status to bring about a more just and equal wizarding world.
In a time travel fanfiction where Harry Potter becomes a god, he would be in a unique position. Firstly, his time - traveling would not be restricted by the normal rules. He could visit any era he wishes. He could go back to the time of the four founders of Hogwarts and learn from them directly. As a god, he would be able to bestow magical gifts on his friends and allies. He could also change the genetic makeup of some wizarding families to remove the taint of dark magic. This would have a profound impact on the future of the wizarding world. He could even create new magical creatures or spells, as his power would be limitless in this fanfiction scenario.
