Berserk was originally constructed in the image of Godzilla by the J.S.D.F. However, the mech became infected by a computer virus, causing it to become self-aware and begin to evolve itself. Berserk began to assimilate other machinery into itself, becoming a huge mass of wires and metal.
- Berserk was an early prototype for the Heisei Mechagodzilla.
- Berserk becoming possessed by a computer virus and turning against its creators is similar to how the Millennium Mechagodzilla becomes possessed by the first Godzilla's spirit and turns against his creators. It's also similar to how the MonsterVerse Mechagodzilla becomes overridden by King Ghidorah's consciousness and turns against it's creators.
