The Beam Magnum comes from Mobile Suit Gundam Unicorn, where it is the main rifle of the RX-0 Unicorn Gundam piloted by Banagher Links. In the series the weapon is shown as unusually powerful for a handheld beam rifle, firing a concentrated shot that can destroy mobile suits in a single hit. Clips of its firing sound circulated among Gundam fans and anime editors online, becoming a go-to effect for mecha fan edits, AMVs and parody battles where one exaggerated energy blast needs maximum impact.
