This is an unnamed species of sapient blue-skinned humanoids with an unique method of communication.

Biology
They appear to be humanoid creatures with blue skin, colorful eyes, light-colored hair, elf-like ears, canine like mouths, and antennae which are used for communication, suggesting that this species doesn't possess any ability to speak.

History
Three members of the species, consisting of a mother and her children, found themselves surrounded by an army of beetle drones that were later destroyed by Jack. It is unknown if they would still have been transferred to Earth even without Aku's rule in the future.
