Berserk

Balsack バルサック (Barusakku) is an unused from the unmade 1993 Godzilla film, Godzilla vs. Balsack.

History
Balsack 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. Balsack began to assimilate other machinery into itself, becoming a huge mass of wires and metal.

Trivia

 * Balsack was an early prototype for the Heisei MechaGodzilla.
 * Balsack 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.
