Slade had received the kick in the back, but it only slowed him down for a second. He grabbed the arm holing his a swept his leg for Batman. Anticipating what would probably happen next, he jumped back once more.
He didn't bring his Bo staff with him this time, but he figured it would just give Batman something to grab a hold of. He eyed Batman and the now armed Batgirl. It would seem in a straight fight Batman and Slade were more or less matched equally. By his estimates, Batgirl herself would give him little difficulty. However, her presence tipped the balance in Batman's favor. He decided this test was over now. He clicked a signal beacon on his belt, and seconds later a camouflaged helicopter swooped down from a rooftop.
Slade back flipped into the chopper's hold, and held a button out in front of him.
"There were more bombs set then what I activated. The automatically disarm themselves after twenty four hours, but they're active at the moment. All I have to do is push this button and possible hundreds of innocents go up in flames. These bombs unfortunately give off a unique energy signature that makes them easy to track. I'll give you a three day grace period to find them before I have them rearmed. Oh, and it probably goes without saying this, but follow this helicopter, and I pull the trigger. So long, Batman,"Slade yelled over the sounds of the helicopter, making sure they got the message.
The helicopter flew off, gaining altitude before its cloaking device reactivated itself.
