- Meta example: the fact this story exists to the eyes of fans of Kara Zor-El, Barbara Gordon and their team-ups. Both characters had been Stuffed into the Fridge in The '80s, and in 1998 there was no sign that Kara would show up in the post-Crisis universe or Babs would become Batgirl ever again.
- When Batgirl banned parahumans from Gotham, the Justice Society fought Barbara... and lost.
- And the only hero who successfully defied her ban was Supergirl when she flew to Gotham.
- Supergirl punching the Joker out.
- Both girls teaming up and defeating the worst enemies of the heroes who were their mentors in another universe.
