DARK ENERGON CYBERTRONIC

Dark Energon Cybertronic represents the raw, corrupting force of Dark Energon—the 'Blood of Unicron' and 'Anti-Spark'—materialized into an active Cybertronian form. Originally a dark lore element capable of reanimating fallen Transformers into mindless Terrorcons, it has evolved into a distinct conceptual collectible entity within the Transformers franchise.
