The Requiem Blaster is a powerful weapon of the Thirteen that is able to draw power from a quasar’s sound waves, a supernova’s thermal energy, or a black hole’s gravity. The blaster is massive enough to have its own gravity and is far too large for a modern Transformer to wield or even pull the trigger. The former archivist Optimus Prime has never encountered any record of a Transformer surviving a direct hit from the Requiem Blaster. It might just be the most powerful weapon ever.
