Seeing as how a dumb amount of villains had teamed up, this qualified as a worldwide disaster. After getting smacked at the watchtower, the Justice League realized they had to create a real plan. They weren't going to defeat this rapidly growing rendition of the League of Doom by brute force.
For want of a headquarters, Superman, Batman, Wonder Woman, the Flash, Green Lantern, and Aquaman had opted to meet in the batcave. Although Robin and the former robins understood the gravity of the situation, they saw no point in moping about it if they weren't allowed to join the meeting.
They instead amused themselves by having a many- way wrestling match in an adjacent room, with Barbara as the referee. It made a lot more noise than they thought.
"If we attack from the west-" CRASH!
"DIE FOUL BEAST!" (They tended to get a bit personal when wrestling.)
"DICK! JASON! TIM! DAMIAN! BARBARA! CASSANDRA! STEPH! QUIET!" Batman shouted for the fifth time.
"You have too many children," Flash said.
"That's not what matters right now," Batman replied, not even denying it. "We need a viable strategy- if everyone fights their own nemeses, we will know what to expect, but so will they."
A crash shook the wall. Most all of the sidekicks and former sidekicks were communicating in the odd, chirping language of their own invention by now. Cassandra screeched in an almost mocking tone, to which Barbara responded with a chastising chirrup. Cass tweeted apologetically.
Batman got up from his chair and stormed to the door. Slamming it open, he let loose a massive "SCREEEEEEECH!" followed by a rapid "SCRAW- CK CHKCKCHK- SSSSKCKCKS-" and a final "rrrrraAaAaAAAAaSKSCSKSCRA!"
Utter silence. Batman slid back into his seat. Green Lantern voiced the thought in everyone's mind.
"Bruce- you speak chirp language?"
Batman raised an eyebrow. "Yeah, of course. Didn't you know that?"
