Great American cockroaches, colloquially called Radroaches, or Giant Cockroaches, are giant versions of the pre-War species that have been mutated by radiation. Cywren Caster has been killing them since she was a child. Cywren is alerted that they are in the area by means of hearing them "Shuffling around!"


  • Jordan considers them Cywren's worst enemy.
  • Ironically, due to defeating the Radroach king, Jordan considers Cywren to be their new leader.
  • A Radroach was the first thing Cywren killed, when she was ten.
