“That’s no moon. That’s a space station.”
Grand Moff Tarkin (Peter Cushing) controlled the Death Star, which is hands-down the most intimidating weapon in history. Also known as the “ultimate weapon,” the Death Star is a floating space station the size of a moon. It has the capability to destroy an entire planet in the span of a few seconds.
Of course, both Death Stars seen in the Star Wars films were destroyed, but it does not take away from the epic status of the weapon. Though one downfall (apart from that one pesky and obvious design flaw) would be the lack of maneuverability. The Death Star is relatively slow. Unlike handheld weapons like the lightsaber, it requires a massive tactical team to fire even a single shot.
Some would argue the lightsaber is more memorable than the Death Star, but a ligthsaber is no match for the Empire’s ultimate weapon. Nor are any of the others on the extensive list above. So, pick your favorite weapon and let the debate begin.
