Thousand Arms Armor (千手の鎧 Senju no Yoroi) is one of Erza Scarlet's armors.
Four Artificial Arms: This armor grants its user the ability to control four additional artificial arms, giving them the ability to fight with a total of six arms and wield six swords at the same time. Each artificial arm is connected to an SE-plug (Self-Energy plug) (ＳＥプラグ Esu-Ī Puragu), a small, device that wraps around the user's wrist, converting their Magic Power into fuel and can be moved separately. Due to the additional arms, this armor ends up being quite heavy.
- One-Handed Swords: This armor comes equipped with six swords with vajra-shaped hand guards and pommels, with each sword having double edged blades.
