AppearancesArmored Core: Verdict Day

Jack is a mercenary encountered in Mission 08-4 of Armored Core: Verdict Day.


Origin: Galef Plant. Male, age: 28.

After a long period of unremarkable performance, his talents seemed to flourish overnight. His reason for the sudden skyrocketing of his skills: an emblem, taken from a downed AC he chanced across in the field. While colleagues cheered him as a symbol of good luck, he began to exhibit increasingly strange behaviour. The origins of the emblem remain unknown. He is defeated by the Lone Mercenary at Galef Plant.

  • He appears as a reference to Flame Fly from Armored Core V. His AC shares the same general appearance and color scheme, and the emblem of Rotten Fly is a deteriorated versions of Flame Fly's.
  • The pilot's and AC's name also seem to reference the book Lord of the flies. In the book, Jack was once rational but never violent only up until he desired nothing than the thrill of a hunt to kill a pig.
  • One possible theory for Jack's behavior and change is that he was an early experiment by the Foundation to see if they could transplant the skills/personality of a long dead person into another one. If so, the experiment partially succeeded as Jack's talent "flourished overnight," but resulted in severe mental instability.
