well one of several super girls, Cir-El (different from the usual Kara Zor-El/In-Ze that appears on DCAU and majority of comics) is basically supermans descendant from the future. Given the limited range of story possibles for people from the future, her and Impulse would have quite a few things in common i'd think.
