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 Kiryu becomes possessed by the first Godzilla's spirit and turns against his creators.
- Beserk has some similarities to the Marvel supervillain Ultron who is also able to possess and control machinery.
