Magnetic Attachment Boomerangs are non-lethal, electromagnetic weapons used by the Dorssia Military Pact Federation to capture units during their security enforcement operations using magnetic fields. The shooters for these devices are seen attached to the outside of the shorter fingers of the Ideal's claw but appear to go inactive when the shooter devices are destroyed. They were used in a few attempts to capture the Valvraves.

They first appear in episode 7, and in episode 8 L-Elf concocted a plan to have sea-water flushed into space to freeze the boomerrangs off the Valvraves.
