In avengers time travel stories, the way they dealt with different versions of themselves was quite engaging. When they traveled back in time, they encountered their past selves. This led to some really interesting and tense moments, especially when they had to work together or avoid getting in each other's way while still getting the job done. For instance, when they went back to get the Power Stone from Morag, there were some tricky situations involving their past and present selves.

For a Bardock Time Travel Fanfiction, an exciting plot point could be Bardock traveling to a time where there is a Saiyan - human hybrid civilization. He is initially distrusted because of his pure Saiyan heritage. But as he proves his good intentions, he helps them defend against an ancient evil that threatens both Saiyan and human DNA. Another plot point could be Bardock going back to the time of the first Super Saiyan. He tries to understand the true nature of this transformation and whether it can be harnessed in a different way. Also, he could time - travel to a time where the Saiyans are at war with a new, unknown alien race. Bardock has to quickly learn about their weaknesses and lead the Saiyans to victory.
One idea could be that the Hulk travels back in time to the moment when he first became the Hulk.

Maybe he teams up with a younger version of Bruce Banner to find a way to control the transformation without the need for the Hulk to exist in such a violent form.
Well, in some fanfictions, the time travel might go wrong in a way that it starts to merge different timelines.

This can lead to a lot of interesting character development and conflict resolution.
There might be a story where during time travel, the Avengers' powers mix with the magic of the Harry Potter world.
