Sonic World Heroes Mission

An Alien race called the "Alphabets" are a race that go to different planets and universes to absorb and conquer. This is their way of living, it is their lifestyle which they have been doing for centuries and Mobius has been struck by them too, which the Alphabets has made it their territory.

Sonic and everyone else with the help of Dr. Eggman had to run off to the Death egg which they set up a military base to fend of the alien race.

They formed a military base called "World Heroes Force"

Mobius is gone, families has been slaughtered all that left are the remaining 2,000 survivors in the death egg.

For the first time ever will the story end with Sonic being defeated?
