Following years of training, Bruce took to the streets of Gotham City to dispense justice in the Gotham season 3 finale and will continue to evolve his superhero identity in season 4.
Gotham will mark the first time that Scarecrow uses the weapon in a live-action setting, adding more flavor and terror to the character.
In addition to establishing the new status quo of the eponymous city, the Gotham season 4 premiere brought out the first big villain of the season.
Butch will soon reemerge as Solomon Grundy and Professor Pyg will be showing up in Gotham season 4 too.
