If Kylo Ren went back in time in fanfiction, he might try to change the events that led to his fall to the dark side. Maybe he would go back to a time when he was still Ben Solo and prevent himself from being influenced by Snoke. He could use his knowledge of the future to avoid the mistakes he made.
One possible scenario in a 'Kylo Ren goes back in time' fanfiction is that he goes back to the Clone Wars. This would put him in the middle of a very different galactic conflict. He could interact with the likes of Obi - Wan Kenobi and Yoda. His presence might disrupt the balance of power, but it could also give him a chance to understand the true nature of the Force from the perspective of these great Jedi Masters. And who knows, he might end up changing the course of the entire Star Wars saga.
They might change the course of history and prevent some major disasters.

Kylo Ren was originally Ben Solo. He was the son of Han Solo and Leia Organa. Ben was strong in the Force but was seduced by the dark side. Snoke took him under his wing and trained him to be a powerful Sith - like figure. He then took on the name Kylo Ren, causing much pain to his family and getting involved in the conflict between the First Order and the Resistance.
Well, in this fanfiction scenario, they could team up. Anakin and Kylo Ren could realize that they have a common enemy, perhaps some new dark force that has emerged in the galaxy. Together, they could combine their skills and knowledge of the Force. Anakin's mastery of lightsaber combat and Kylo Ren's more unorthodox fighting style could make them a formidable duo. They would also have to overcome their differences in ideology, with Anakin believing in the Jedi way (even after his fall) and Kylo Ren having a more muddled view of the Force.
Kylo Ren would be different in a Clone Wars - set fanfiction because he'd be out of his normal time period. He'd be surrounded by different technology and a different kind of warfare. His dark side powers might seem more extreme compared to the Jedi of the Clone Wars era. Also, his modern - looking lightsaber would be quite distinct from the ones used then.
Kylo Ren's character could develop in a more positive way. If he goes back in time, he might see the mistakes of the past and decide to be a better person. For example, he could see how the Sith's ways led to destruction and choose the path of the Jedi instead.
One possible scenario in this fanfiction is that Tempest Shadow is intrigued by Kylo Ren's dark side. She has seen power in different forms in her own world, and Kylo Ren's power in the Force is something new and fascinating to her. Kylo Ren, on the other hand, might view Tempest Shadow as a tool he can use to further his own plans in the galaxy. He could try to manipulate her, but Tempest Shadow is no fool and would resist, leading to a power struggle between them.
Alternate timelines are also popular. For example, Kylo Ren could go back in time and create a completely different future for the galaxy, perhaps one where the First Order never rises or the Jedi Order is saved. This allows for a lot of creative exploration of the Star Wars lore.
