God Key (or Grand Key/Divine Key when translated from Chinese) are weapons marked as 'God (or Herrscher) Killer'. These weapons were initially designed and produced by Professor MEI, who worked as a chief researcher at the organization Fire Moth. Her research and weapons were a key to defeating 13 Herrschers. She, however, did not complete a form of each God Key. If the Key was almost ready but needed more time to properly contain the power of the core, it was left in a safe cube shape.
God Keys are made from actual Herrscher cores from previous civilization (except Hollow Armor), and they were not made from 14th Herrscher cores (which was sealed on the moon by using Selene) as the pre-civilization era were destroyed before even able to use those cores. The cores from God Keys does work independently from 14th Herrscher cores, thus they are not dissipated away although there are new Herrscher from current civilization with the same Herrscher title and ability.
