Powers & Abilities[]

  • Superhuman regeneration: Gilbert possesses a rapid rate of regeneration which is only active when he has been inflicted with grave injuries and blows that can cause instant death. This is shown when Gilbert's head is cleaved in two by a "beyond" creature who had stolen Phillip's brain, but can still hold his consciousness and killed the creature shortly thereafter. But this power doesn't nullify the pain which comes from the injury.
  • Visceral Heavy Industry (ヴィセラル重工製 Viseraru Jūkōsei?): Gilbert's car arms itself with different weapons to fight against enemies.
    • Plasma Cutter (プラズマカッター Purazuma Kattā?): Gilbert's car arms itself with a three-eyed laser which can cut through any tough substance.
    • Bethesda Firearms Death Caliber .50 (ベセスダファイアアームズ製デスカリバー。50 Besesuda Faiaāmuzu-sei Desu Karibā Pointo Fifutī?): Gilbert's car summons machine gun turrets from the car and shoots to kill its enemies.



  • In the Original Oneshot, Gilbert was a Mummy, but this has obviously since changed.
  • Despite being flawless in working around the building, he panics when dealing with mice.
  • Gilbert's middle initial is "F" which is short for "Franke".
