It could be a character from a completely different dimension. Suppose there's a crossover element in the fanfiction. A character from another anime or fictional universe somehow ends up in Ichigo's world after his revival. This character has different abilities and a different perspective, and they see Ichigo as a potential ally against a common enemy that exists in both of their worlds.
An unexpected ally could be an old enemy from his past. Maybe a Hollow that he once fought and defeated now sees a greater threat in the situation after Ichigo's revival and decides to team up with him. For example, the Hollow might have information about the new forces that are emerging since Ichigo's return and offers to share that in exchange for some form of protection or mutual benefit.
