Batman and Superman have faced each other several times in the past, but few battles have been won so decisively and so quickly.
Spoilers incoming for Batman #42, so if you haven't read the issue yet you've been warned.
Poison Ivy is currently controlling...well, just about everyone, everyone except for Batman and Catwoman. The two leave Wayne Manor and head to get a bite to eat, with Superman following them from the sky. He just hovers in the air, watching, though to be fair it is Ivy watching through him.
As they arrive
Turns out a whistle does incredible damage to someone with superhuman hearing.
As they walk into a house, Superman can be seen falling from the sky. It seems they discussed this plan beforehand, with Catwoman saying "Okay. I was wrong. You did it. Superman with a whistle." Batman points out that this isn't really Superman though, as "Clark knows when to listen and when not to listen"
It's a perfect moment and just goes to show that a man with a plan is just as dangerous as someone with superhuman powers.
You can see the images above.
