Kids' Club War

"Long ago, the Ancientmen knew how the Kids' Club war is all about how a group of kid heroes and teens fought against the Empire of Darkness, an evil armada of minions from kid-friendly movies, TV shows and video games. It seemed that it's been thousands of years before I was born. How can that be?"

--Su Ji-Hoon, The Ancient Stories

The Kids' Club War was a destructive war fought between the Kids Club and the Empire of Darkness (the faction that the Coalition of the Red Star was formed from).

The conflict took place thousands of years before the Third World War and it involved a vast majority of the multiverse's factions, including all of the great powers that would eventually form two opposing military alliances: the Grand Alliance and the Coalition of the Red Star. Various high-tech weapons were made during the war, and the Empire had conquered many worlds across the multiverse.

After Earth overcame the initial shock of the EoD invasion, the Alliance armadas regrouped and annihilated the Empire of Darkness and has liberated worlds under EoD occupation, forcing the remnants of the Empire (including their Emperor), to exile themselves to Exegol.
