Mon Dieu! is the title of the first short story in The Umbrella Academy series. The title is French for "My God!" and is a quote in the story. It was created by Gerard Way and Gabriel Bá and released by Dark Horse on their website on November 2, 2006.
The story takes place during the Apocalypse Suite era where The Boy and The Séance are in a lab. The Séance is attached to many machines and The Boy explains that he can now no longer use his powers in fear that he will de-age himself to infancy, so he has decided to attempt to send The Séance through time. The Séance ends up on a battlefield in France during the Middle Ages as a commander when a soldier tells him that they are losing the battle and must regroup and wait for reinforcements. Both are then killed by a cannon blast, which causes The Séance to reappear in the present (some time after his initial trip), and when The Boy asks what happened 00.04 exclaims "Mon Dieu!"
- "Commandant! Nous n'arriverons pas à tenir! Nous devons nous regrouper et attendre les renforts--" = "Commander! We can not hold the support! We need to regroup and have to wait for reinforcements--"

- "Ne vous embettez pas à mourir ! Si nous tenons bon--" = "Do Not being bothered dying! If we hold our ground --"
- "Un moment --!" = "Wait a minute --!"
