|"Bomb Maximum Drive!"|
Shroud Magnum (シュラウドマグナム Shuraudo Magunamu) is Shroud's firearm and only weapon, a red-colored version of Double's Trigger Magnum (or Skull's Skull Magnum), as Shroud lacks a Gaia Driver and Dopant form, unlike her family.
She also owns a refined Gaia Memory, called the Bomb Memory (ボムメモリ Bomu Memori).
When the Bomb Memory is set into the Shroud Magnum's Maximum Slot, and then the gun is set to its Maximum Mode (マキシマムモード Makishimamu Mōdo), it initiates the Bomb Memory's unnamed Maximum Drive: Shroud shoots out a sphere of energy which splits into smaller spheres that explode.
