His intent is to complete the contract with his brother to "kill God" in order to stop humans from fighting among themselves while remaining true to each other. However, V.V. murdered Marianne out of seeing her as a hindrance for his brother and sets up the official assassination, breaking his promise of mutual honesty between him and Charles when he lied of his part in Marianne's death.
V.V. briefly appears in episodes 18 and 19 of the first season, where he transports Lelouch, Suzaku, Kallen, and Euphemia to Kaminejima, then collapses the floor beneath them later on. Immediately prior to the First Decisive Battle of Tokyo, he appears before Suzaku and explains the nature of Geass, using Euphemia's uncharacteristic actions resulting in her death during the establishment of the Special Administrative Zone of Japan to entice him. He subsequently kidnaps Nunnally, resulting in Lelouch's sudden abandonment of the Black Knights mid-battle, crippling their chain of command and causing their defeat.
In the second season, V.V. starts to work behind the Emperor's back by sending the modified Jeremiah to assassinate Lelouch. However, this backfires; Jeremiah betrays him and sides with Lelouch, in the process betraying V.V.'s location. During Lelouch's assault on the Geass Order, he pilots the Siegfried against the Black Knights. Though he manages to hold his own at first, he is caught off-guard by Cornelia, who has jury rigged a damaged Akatsuki with an array of weapons. She and Lelouch destroy the Siegfried together. Heavily wounded, V.V. manages to reach the Twilight Gate to the Thought Elevator in the Order's complex only to find Charles waiting for him. He attempts to lie to his brother again but dies when the Emperor takes his "Code" and immortality.
In the PlayStation 2/PlayStation Portable video game, Code Geass: Lost Colors, V.V. is sighted on Kamine Island with Rolo, who also gained his Geass from V.V.
