Robin jumped down and swiped two guard off their feet with his staff then hit them in the head with it. Batgirl and Nightwing through the windows.
"Not just Batman." Nightwing said.
"The whole Bat family is here. Well isn't this great! Get 'em boys!" Black Mask entered the truck and closed the back, Batman through a tracker on it.
Black Mask's men run at the four, Batman and Nightwing wake on half of them while Batgirl and Robin take on the other half.
"Heads-up!" Nightwing uppercuts one of the guards and Batman kicked the guard in the back, sending him to Robin, "Batter up!" Robin swings his Staff at the flying guard, and Batgirl finishes the guard by jumping over the guard, grabbing his legs and slamming him on the ground.
They keep fighting the guards, one was left, the guard tried to crawl away, but Nightwing stepped on the guard's back.
"Yeah no." He said.
"Who is Black Mask sending the drugs to?" Batman asked.

"Thanks for your time." Nightwing knocks him out.

"Batman, nice work, I see you brought the rest of the family. Nightwing."
"Commissioner." Nightwing shook his hand.
"Roman was going to sell drugs with Penguin." Batman said.
"Great, and here I thought the two hated each other, where is the truck heading?" Batman pulled up his tracker and showed Gordon.
"I also hacked into their communications." Cash walked up.
"Cool, let's have a listen." Batman played the transmission.
"This is not how I saw my day!" Black Mask shouted.
"Don't worry boss, we have explosives in these drugs for the Penguin at least, good thing Batman didn't get them."
"Yeah, but we didn't know he would bring Nightwing in this."
"Whatever, I'm glad the GCPD didn't show up when this happened." Black Mask said.
"Or their new pig, what was that Officer's name again, ah it slipped my mind, I heard he took out Victor Zsasz and The Riddler!"
"Took out? You mean he-
