Invasion of Cartoon Network City

"Oh my. I remember the CN City bumpers when I was just at the late teens, watching Cartoon Network, but I only saw them sometimes, but since the Principality of Zeon had come to side the Coalition of the Red Star, we're all in a huge screw-up once again! Looks like it's the door to the invasion of my village too, but let's hope the Earth Federation would come to save this city."

--Su Ji-Hon, Zeon Dawn

The invasion of Cartoon Network City is a Principality of Zeon-led attack on Cartoon Network City during World War III.

As the USRAC War gets more intense and weeks after taking over New York City and days after the Second Beacon War, the Unified Soviet Red Assault Command Army and the Principality of Zeon Armed Forces travel to Cartoon Network City together for a surprise attack and an invasion in order to help Fauwan, the Southern Song Dynasty, the Krasnyy Corporation, the United Red Space Command, the Werman Reich, the Unified Capitalist Revolutionary Dictatorship, the Galactic Empire, the Nazi Union, the Redcoat Union, the Irken Empire, China, Russia, North Korea, the Empire of the Rising Sun and the rest of the Coalition of the Red Star get their way to take over the city.

When the invasion of Cartoon Network City began, paratroopers, Zakus, tanks and aircraft started to wreck havoc on the city, Su Ji-Hoon, the Preschool Girls, Team Magic School Bus, Team JNPR, Team Disney Princesses and the Sonic Alliance help the Cartoon Network heroes attempt to repel the invasion.

When the situation is getting grimmer due to the Coalition of the Red Star's swift invasion, Miles Callisto sends in the United States Army, the British Army, the NATO, the Republic of Korea Army, the Republic of China Army, the Japanese Self-Defense Forces, the European Union Enforcer Corps, the United Nations peacekeepers, the Atlesian Armed Forces the Future Army, the United Nations Space Command, the United Schnee Liberty Command and the ANZAC Corps to defend Cartoon Network City for reinforcements, then the Gilgamesh Confederation and Balarant Union declared a war on each other, foreshadowing the Gilgamesh Confederation-Balarant Union War.

The Preschool Girls also meet the Soviet Preschool Girls for the first time since the Beacon War, and now these two factions fight each other due to the USRAC War.
