General Information
Occupation Bomb
Affiliation Master Plan

The FPNB (Fully-Primed Neutron Bomb) was a WMD with a four-megaton yield and a blast radius of 6 miles (9.6 km). It was used by Bane to terrorize Gotham City and a primary reason for the execution of Operation 98H1.

Originally a fusion reactor created by Wayne Enterprises and intended as a clean energy alternative, the bomb was reprogrammed by Dr. Leonid Pavel when Bane left him no choice, threatening to end the lives of eleven Wayne board members and possibly his own family.

Pavel first heard of the device at the IEEE Symposium in 2009. Although the exact methods used to reprogram the device are unknown, it is to be noted that the core itself was removed, reassuring the bomb's detonation in December 2013 (five months by Bane's calculations).
