Often, Aizen can still be a major antagonist even in time travel fanfictions. His schemes might extend across time, and Ichigo and Orihime have to figure out how to stop his plans that are messing with different timelines. Another could be the more powerful versions of Hollows from different time periods. They might be stronger and more menacing than the ones Ichigo and Orihime are used to in their original timeline.
The antagonists could also include time - based entities. For example, there could be a being that feeds on the chaos caused by disrupting the timeline. Ichigo and Orihime's time travels create this chaos, and this entity tries to stop them from fixing the timeline because it wants to continue to thrive on the disorder. Additionally, if they travel to a future where an evil version of Ichigo has taken over, that version of himself could also be an antagonist as they try to set things right.

There could also be rogue Shinigami from the past who oppose Ichigo and Orihime's attempts to fix the timeline as it goes against their own self - interests.

This could lead to a completely different world in the present, with new alliances and enmities.
