It's the potential for alternate timelines. Dark Ichigo has his own motives and desires, which are often in contrast to the main characters. When he time travels, he can completely change the course of events in the Bleach world. For example, he could prevent certain battles from happening or change the relationships between characters. This creates a whole new set of stories and possibilities that are really engaging.
The mystery. Dark Ichigo is already a complex and somewhat mysterious character in the original Bleach series. When you add time travel to the mix, it becomes even more so. We get to see how he might interact with different versions of characters from different times, which is really exciting.
The exploration of Dark Ichigo's character is a big part. In time travel fanfiction, we can see different sides of him. Maybe we see a more vulnerable side if he travels to a time when he was first created. Or we might see him become even more powerful and malevolent as he gains knowledge from different time periods. It also allows for unique character interactions, like with younger versions of Ichigo or other Soul Reapers from the past, which makes for a really interesting read.
