Exeron War

The Exeron War was a full-scale war between the World Resistance League and the Supreme Government in the events of Exeron Fighters, taking place after an Exeron match between Lincoln Loud and Jacob Two-Two. It was the largest military conflict in the history of mankind and many other cartoon worlds, taking the lives of 10 billion people. Within a span of three years, 108 cartoon worlds were outright affected by the Exeron Tournament, as the Supreme Government began a systematic and genocidal campaign of wiping out all cartoon characters and proving humans are better than them by holding the Exeron Tournament. The onslaught was halted when humanity and cartoon characters coordinated a multiversal counterattack after the United States managed to siege the Grand City, the capital city of the Supreme Government, and destroyed it when giant the last resistance mechas assaulted the cappital with a thermonuclear bomb and one of these mechas' nuclear reactor, thus ending the war in resistance victory.

The conflict drastically altered the political alignment and social structure of Earth. Humanity and cartoon characters set aside their previous cultural and nationalistic rivalries together and united multiversally. The Multiversal Defense Force was established to defend Earth, many cartoon worlds, humanity and cartoon characters from future threats.
