Sir Violet served as matriarch of the Cthulhu race, guiding her people through space after their homeworld's destruction. Her existence transformed when their ship encountered an ancient wish-granting machine. Overwhelmed by despair for her children's survival, her fear activated the device, birthing Big Gold—an entity merging with her consciousness and the ship.

Big Gold usurped control, imposing a fascist regime on the once-idyllic Cthulhu society. Sir Violet's appearance warped; she donned ominous black robes, her eyes glowing red. Dominated by Big Gold, she spoke with a masculine voice, starkly contrasting her original feminine tone. The peaceful vedim creatures mutated into parasitic bioweapons for conquest.

As Big Gold's puppet, Sir Violet orchestrated Earth's invasion. She deployed vedim parasites to infiltrate and replace humans, commanding warriors like Cobalt and Sepia who piloted mecha such as Delos Theta. She authorized the creation of Iczer-2 to counter the rogue Iczer-1.

Fragments of her original personality—her idealism and maternal concern—sometimes surfaced, revealing internal conflict against the imposed tyranny. These attempts at resistance proved futile against Big Gold's absolute dominance. When the Earth invasion failed due to Iczer-1, Big Gold executed Sir Violet for her failure.

Her narrative forms a tragic arc of corrupted leadership, where her compassionate intentions were weaponized. Her altered design and dual voices externalized the conflict between her benevolent identity and the malevolent force controlling her. Her fate cemented her role as Big Gold's victim.

Her character development and resolution are confined to the original narrative.
