The Great War is an event mentioned in the Sonic the Hedgehog comic book series and its spin-offs published by Archie Comics. It was a conflict between the Kingdom of Acorn and the United Federation instigated by the alliance of Dr. Eggman, Dr. Julian Snively, and Walter Naugus.
The Great War came about as a result of the efforts of Dr. Eggman and his cohorts, who had managed to convince King Acorn that they were friendly to the Kingdom of Acorn. With Snively playing a leading part in the act, they persuaded him that the United Federation intended to secretly invade the kingdom, which outraged the king and led to the conflict. Unfortunately, he played right into the villains' hands, as the war enabled Eggman and Snively to seize control of the kingdom for themselves. They then exiled the king and Walter Naugus to the Special Zone, from which they would not return until an unknown amount of time later due to the efforts of the New Freedom Fighters.
- The Great War is based on the conflict briefly mentioned in the Sonic the Hedgehog animated series.
