They sport black armor with a single black plate on their back. Their most unique ability is to create portals, allowing them to appear and disappear at will. The opening of these portals has a devastating effect on unshielded people, turning them into pillars of salt.
One of the Torwart units was destroyed by the Super Evangelion, but the other survived and reappeared with Super Evangelion's Center Trigonus, which was previously taken by Armaros using the Spear of Longinus. Due to the particular relationship between Shinji and S.EVA, the second unit behaves as if it is Shinji.
This unit mimics the voices of the two people it loved most. In the first form of Armaros, it used the voices of Asuka and Rei in the case of Shinji. When Armaros took Hikari, it adopted the voices of Kodama Horaki and Toji Suzuhara.
