Big O shields itself right before the Bonaparte tries to drill into it. After seeing an image of Dorothy being in danger, Roger allows Big O to continue the fight on its own and makes his way to abandoned church in Dastun's car. Alan prepares to destroy Dorothy, ignoring Angel's pleas. Roger arrives to confront Alan, but Dastun soon interrupts the match. As Bonaparte then begins to destroy the city dome under Vera's command, Alex activates his newly modified Megadeus, known as Big Fau, and quickly destroys Bonaparte. However, Big Fau begins to malfunction, causing chaos within the dome. Roger returns back to Big O and restrains it until it shuts down.
