What a terrific picture!
There are two things, which I see. If "Batman" is being effected (affected?) by Metallo's Kryptonite, it seems to me that it isn't Batman but Superman in Batman's costume....er... uniform. That could be Lois Lane attacking Metallo, but from this back view, it could just as easily be the real Batman in drag coming to Superman's rescue.
I see an interesting storyline where someone has come after Superman, so they come up with this plan to hide him from the criminal element, but still allow him to help, only to have it backfire on them when they run into Metallo. I think the best scene though, would be them explaining to Lois why Batman is dressed up in drag impersonating her.
