Arkham Knight Incident
Several rioters could be seen all throughout Gotham City causing riots. Batman saved one of the GCPD Officers, who was being held hostage by them. After firefly caused the firetruck carrying the crew of station 17 to crash, the rioters took this opportunity to capture the firefighters, including Raymond Underhill. When Scarecrow activated the Cloudburst, and released his fear toxin into Gotham, most of the Rioters were affected by It, while some had managed to escape into buildings or high ground. When Poison Ivy saved Gotham, rioters continued robbing Gotham, although many had died on Scarecrows attack.
After Batman arrests all of Gotham's Most Wanted, rioters are still seen in Gotham. They were presumably stopped by the GCPD afterwards.
- Founders' Island is the only island in which riots do not happen.
