Dark Star Saber

The Dark Star Saber is a sword made from pure Dark Energon and forged by Megatron himself during the War for Cybertron. Intended to be a dark counterpart to the Star Saber itself, this blade possesses all the powers of the original blade, and is even stronger than its counterpart. Unlike the original blade, the Dark Star Saber doesn't require a Prime to activate its powers. For a long time the weapon was stored in the Nemesis vaults. However, once Optimus Prime came into possession of the Star Saber, Megatron decided to pull the weapon out of the vault.
