"Bloodlines Across Worlds" An RWBY x Invincible AU Crossover
In the Kingdom of Vale, the name "Omni-Woman" is synonymous with hope. A legendary huntress of peerless strength, Anissa is the invincible shield against the Grimm, a devoted wife to Taiyang, and a doting mother to Ruby. But beneath the heroic facade lies a cold, celestial truth: Anissa is not a savior. She is a Viltrumite-a vanguard of a galactic empire built on blood, sent to prepare Remnant for total subjugation.
On Ruby's sixteenth birthday, the illusion shatters. When her dormant Viltrumite DNA ignites in a burst of violent power, the "perfect" family is torn apart. Her mother's loving embrace turns into a conqueror's grip as Anissa reveals Ruby's true purpose: to serve as the ultimate weapon for the impending Viltrumite invasion. Now, Ruby is caught between two worlds. Haunted by a heritage of conquest and hunted by the Empire she was born to lead, she must decide if she is a monster by nature or a hero by choice. As the skies of Remnant darken with the shadow of Viltrum, the daughter of the world's greatest lie must rise to become its only hope.
