Perhaps in this fanfic, Harry has a vision of a future where saving Voldemort is the key to saving the entire wizarding world. So, he travels to various dangerous and mysterious places. He might meet some long - lost magical creatures who have the knowledge of how to break the cycle of Voldemort's evil. Harry has to overcome many challenges, like powerful dark spells and dangerous traps along the way.
In the 'harry tike travels to save voldemort fanfic', it could be that Harry realizes that Voldemort's soul is connected to some ancient magic that, if not saved, will cause the destruction of magic itself. Harry, being the self - sacrificing hero he is, decides to travel to places where this ancient magic originated. He has to make his way through enchanted forests and old wizard ruins. He also has to face the opposition of some wizards who think Voldemort is beyond saving. But Harry is determined and uses his unique bond with Voldemort (maybe from their shared connection as orphans or something similar) to try and reach the core of Voldemort's being and save him.
Hermione would likely be a supporting character. She might use her vast knowledge of magic and research skills to help Harry figure out where to go and what to do on his journey to save Voldemort. For example, she could dig up ancient texts about dark magic that might hold the key to Voldemort's salvation.
In the fanfic, Harry might reach out to Voldemort to save him because he believes that every life is worth saving. He uses his connection to Voldemort through the scar to communicate.

Perhaps he realizes that Harry has potential that can be used for his own purposes rather than just killing him. So he wants to keep Harry close and away from the Dursleys who are just muggles.
One possible plot could be that Harry tries to reason with Voldemort about the futility of his dark ways. He might talk about how much destruction Voldemort has caused and how many lives have been lost. Harry could also try to appeal to any remaining shred of humanity in Voldemort, perhaps by bringing up his own orphan status and how they both lost their parents in a way, though for very different reasons.
Maybe Harry has all of Voldemort's powers but uses them for good. He could start to look like Voldemort but with a kind heart, and he uses his new - found dark magic to fight off new threats that are even more powerful than Voldemort ever was.

As time passes, Harry becomes an integral part of Voldemort's inner circle, helping him plan attacks against the wizarding world, believing that they are actually for a greater good as Voldemort has convinced him.
Well, one possibility could be that Voldemort adopts Harry as a way to control the wizarding world. He might think that by having Harry on his side, the resistance against him will crumble. Another could be that Voldemort discovers some sort of connection between him and Harry that makes him want to take Harry under his wing, perhaps related to some long - forgotten prophecy.

In this fanfic, perhaps Voldemort has some grand plan. He puts Harry in timeout to wait for the right moment. He might be using this time to gather his Death Eaters and prepare for a big showdown.

Well, it could involve Voldemort having some strange newfound attraction to Harry and trying to make Harry his 'queen' in a very dark and twisted way. Maybe he uses dark magic to bind Harry to him and Harry has to find a way to break free.
