In spite of the misleading cover, this is not a crossover story.
Forget what I said before about Robin getting guest star billing these days. Here he gets no billing at all!
Haney again but not bad. Trevor is credited by the Answer Man elsewhere win this issue as being even younger than Jim Shooter when he started in comics.
Hawkgirl gets billing...but not Robin. She's still a "girl" and not a "woman," though.
