The Monikan War was a battle that occurred near the beginning of the Second Era between General Jeff Cuphead the Inspritable, Giver of L's, controlling the Meme Army, and Monika Sans, controlling the Monika Guard. Not much is known about this event, as it is not elaborated on much in the games.
The War Edit
During the War of the Orb in the First Era, SiIvaGunner won the War because of a mistake caused by Jeff Cuphead. Because of this, Monika Sans swore eternal hatred to him, and began the Monikan War near the dawn of the Second Era. The War was waged over many universes, taking control of many of them. The battle was waged until Jeff Cuphead fell through Dayman's wormhole, and soon after he defeated Monika Sans.
