The Death Star has a reputation as the most powerful superweapon in Star Wars history, as it can obliterate an entire world in a single blast. In fact, the only weapon that’s more powerful is Starkiller Base from the sequel trilogy, as it can destroy multiple planets with one shot. However, neither the Death Star nor Starkiller Base are the ultimate weapons in Star Wars. Sure, they’re powerful and deadly, but Star Wars has proven time and again that there are things far worse than death, and one weapon in particular delivers just that.
