The Voxai are a race of psychic beings who are the second-to-last race Sonic and friends will encounter in the Twilight Cage. Their current leaders when Sonic steps into this world are known simply as The Overmind. They do not attack you at first but after Sonic met up with an "outermind" Voxai named Thebes, things started to go out control from there. You eventually meet up with an enemy Voxai guadian named Thelxe. A bit afterwards you'll fight the Chaos Emerald corrupted Overmind leaders. After they have been defeated, Thebes will take over the leadership position and relead his people.
