Newark airport lies in a flooded region SE of downtown.
It housed awarehouse serving as a cache for dried super-strong jalapeno peppers bio-engineered during the Salsa Wars. They were discovered close to the rising water table. Hwever if they would leach into the aquifer it could render all wells unusable. The Superhero League of Hoboken was sent to remedy the problem. The Iron Tummy used his ability to eat all of them.
Sometime later Dr. Entropy occupied the airport's control tower to bioengineer a species of hostile pigeons.
