Not the way you're describing.
Why can she keep up with Batman in terms of fighting ?
>You don't need to manage anything.
Yeah you do, you can tell them to run fast but not dodge fast.
I'm so fucking tired of Harley Quinn you guys
Harley Quinn is not fucking crazy
When it comes to Batman, the default answer will always be: IT'S A SEX THING.
I dunno, being controlled by a plant lady by what I assume is some kind of chemical drug thingy could probably mess with their reaction time.
Nah. If anything, the very comic itself implied that the characters controlled by Poison Ivy had their super-powers/senses amped because she couldn't control them as well as they could, so she wasn't able to restrain herself using them as they could if they were in control of themselves. That's why Superman was taken down by Batman with a simple whistle when Poison Ivy used his super-senses to hear on Batman and Catwoman conversation, and as well Superman pretty much killed Batman with a soft punch.
Well, while it would be the first time Americans have ignored their constitution, I'm sure they'd be able to stomach it.
Friendly reminder that NightWing tapped that.
