The United Federation is a group that appears in the Sonic the Hedgehog comic series and its spin-off comic series published by Archie Comics. It is a human government known to occupy a large area of Sonic's World. It is allied with the Kingdom of Acorn in the fight against the Eggman Empire, and employs its military forces in an effort to see the mutual threat defeated.
The United Federation was an early victim of Dr. Eggman's bid for world domination, as the renegade G.U.N. scientist convinced King Acorn that they intended to invade the Kingdom of Acorn. This enabled Eggman to seize control of Westside Island and other territories of the kingdom. He would eventually set his sights on conquering his former homeland.
Shattered World Crisis
- Note: From the readers point of view, this picks up from where the United Federation's original timeline ended.
The Federation was among the many nations rocked by the Shattered World Crisis, but fortunately had G.U.N. in position to help those affected through Operation: Triage. Unfortunately its troubles were far from over, as the planet's fragmentation left the Federation and its allies with strained resources, which allowed the Eggman Empire's Egg Army units to seize additional territory.
The United Federation maintains a large territory, with its capital being Station Square and various cities such as Soleanna, Westopolis, Apotos, Empire City, Holoska, Shamar, Mazuri, Spagonia, Chun-Nan and Adabat existing within its boundaries. The region is home to a considerable number of anthropomorphic animal races in addition to humans.
