The Requiem Blaster was forged by Solus Prime, the Thirteen's fabled weapon-smith, for Megatronus Prime to defeat Unicron. It was an extremely powerful Weapon able to blow through the mountain behind Solus's testing area. After the test she voted to destroy it as it was to powerful. The vote was 7 to 6, it would be destroyed, and only Solus could ever put it back together again. After the defeat of Megatronus Prime, now known as The Fallen, the Requiem Blaster was lost.
