Back Blades are weapons used by Hydraxon and his duplicate in guarding the Pit. They can be launched mentally by Hydraxon. When not in use, they are stored on Hydraxon's back.
In Prisoners of the Pit, Hydraxon fired a Back Blade at Nocturn's hand, causing him to drop his Squid Launcher.
The Back Blades were released in 8923 Hydraxon, comprised of three pieces attached to ball joints on his back.
