And yes, he actually is canonically from Scranton.

Assume he will try and make his way to the absolute center of the building to cause maximum damage when he explodes. For convenience let's pretend that point is the back wall of Daryl's office. The Dunder-Mifflin employees must stop him from getting to that center point. Dunder-Mifflin wins if they can either incapacitate Nitro or keep him away from the destruction point for 16 minutes (the approximate time it would take for the Avengers to get from NYC to Scranton travelling at Mach 1). Assume Dwight has knowledge of superheroes and villains. The Dunder-Mifflin cast can be made up of any group of employees from any season of the show. Employees from other branches can also show up.

Bonus: Nitro has come to settle up an old debt with the Schrute family. Via violence. Dwight and his family must defend Schrute Farms from Nitro until help arrives in the same approximate amount of time
