Sonic Forces AU where Infinite is the literal personification of infinity, who somehow crashes on Earth one day. It sees the Mobians and their society and decides to take the form of a jackal. Unfortunately, Eggman needs something to test his Phantom Ruby on so he can enact his world takeover scheme, and this entity is the perfect tool for his plans.
Sonic starts to piece things together throughout the AU that Infinite isn't your average day Mobian, but some entity as old as the universe itself. And Eggman is playing with forces he can never possibly understand.
So Sonic decides to shift gears and decides to save Infinite, because Sonic can see how this being is suffering and Sonic never turns away from someone in need of help.
Im calling it, the Ruby Mythos AU
