Sadly these battles were all retconned out of existence by the Infinite Crisises on Multi-Pan-Dimensional Earths of Two or More Worlds.
As long as we’re on the subject, does anyone remember MC Hammer’s old Saturday morning cartoon show. That thing was amazing. I think it followed the one where Bo Jackson was on a super team with Wayne Gretzsky (oh God do I wish I was making that up). I would have hoped that since my youth, kids shows would have taken a turn for the better, but I think only the opposite is true. Oh well, at least these kids get Batman: The Brave and The Bold.
Hammerman!? Dude, yes! With the magic talking shoes that gave him the power to bludgeon criminals with giant musical notes and whatnot! And the theme song: “Hammerman! Hammer! Hammerman!”
