"Welcome members of the Avengers, Justice League, X-men and leaders of the smaller superhero teams." Batman greets everyone.
"Batman why have you called this meeting there usually isn't a reason for all of us to meet like this unless Thanos or Darseid are causing trouble." Superman wonders.
"I was getting to that approximately 5 hours an entire city roughly 5 times the size of New York appeared out of nowhere. SHIELD is already on the scene helping to maintain a perimeter with aid from the military." Batman explains.
"Which means no one has actually set foot inside the city am I correct?" Captain America asks.
"That would be correct Captain which is why we will be entering the city to make contact with the people of this city." Batman answers
Ending the meeting the various teams head to board the Javelins, Quinjets and the Black Bird. Landing outside the various points the teams disembark before entering the city.
