Anti-Magnet-Antennae V2.0 were inventions of Heinz Darthenshmirtz, a Scientist working for the Galactic Empire, designed to nullify the effects of magnets in their vicinity. These devices were deployed by Darthenshmirtz against Perry, a Rebel Alliance agent, to prevent him from utilizing his wrist magnet. This occurred after Perry's clandestine entry into the Death Star where he faced Darthenshmirtz.
