Voxai

The Voxai(ヴォクサー Vokusa?) are telekinetic aliens with four wings shaped like a dolphin's flipper. The shape of their heads greatly resembles a manta while the skin is similar to a jellyfish. They have a translucent, central body mass with a tail identical to an eel's. The coloration of common Voxai is light pink to deep purple while the Overmind, leaders of the Voxai, have distinct colors. The Voxai is the only race that occupies two planetoids within Sector Charyb of Twilight Cage; Colony Alpha and Colony Beta. Their arrival in the Twilight Cage is before the Nocturnus Clan, but also after the Kron. Contrary to other races like the Zoah and the Nocturnus Clan, the Voxai is reasonably insular; meaning they do not have military-type ambitions. They are diligent workers with a quiet, peaceful, and carefree nature. Residents who are connected to the Overmind's psychic signal are known as innerminds while outsiders and dissidents are addressed as outerminds. They always speak telepathically, which is displayed with parentheses over their words in the game. Despite their peaceful nature, the Voxai are one of the most powerful races inhabiting the Twilight Cage. With their psychic and telekinetic abilities, they are able to read, control, and attack the minds of others. They can produce green energy around their wings to use as a weapon and launch waves of psychic energy. Their innate powers also allows to permanently float and move in midair. According to the Codex entry of the Voxai, not even the most strong-willed Nocturnus Clan are immune to being mind-controlled by the Overmind.

Notable Voxai

 * Thebes: Thebes(テーベ Tēbe?) is a local resident of Colony Beta. During the time the Overmind began to enslave their society, Thebes was able to resist its affects and decides to hide as a outermind. He is the one who enlists Sonic and his friends' help against the Overmind's corrupted goals. He assists the group by extracting the teleport key from Thelxe's mind so they can warp to Colony Alpha. Thebes becomes the new Overmind after the defeat of the original members and promises to restore the Voxai society back to its peaceful state.
 * Thelxe: According to Thebes, Thelxe is one of the Overmind's elite protectors. Thelxe is the only Voxai to willingly support the Overmind's oppressive ambitions.
 * Croesus: Croesus(クロイソス Kuroisosu?) is a resident of Colony Beta. His severed connection from the Overmind prevents him from being controlled like other Voxai, but causes him and his family slowly become insane due to the deprivation. When Sonic and his friends investigate the source of this problem, it is revealed to be a signal-blocking technology from the Black Ops team in the north. After they successfully shut down the machine, Croesus and his family will return to normal. However, this create brief tension between Sonic and Tails in the game when Tails examines the device.

Overmind
The Overmind are the controlling intelligence of the Voxai race. They are group of three powerful Voxai; Leucosia(green), Ligaia(orange), and Riadne(blue). They function as a single entity due to their merged minds and constantly finishing each others' sentences. Their authority over their kind typically consists of sending telepathic messages to provide specific instructions. Their combined psychic powers are capable of mind-controlling Voxai and even the Nocturnus Clan. They are also able to enhance the power of the Chaos Emeralds by implementing their psychic energy into it. When the Chaos Emeralds are greatly embedded with psychic energy, its color will change to pink; changing the jewels name to Great Emeralds. The Overmind are the only leaders to willingly ally themselves with Imperator Pir'Oth Ix.
