Adidas Alien is a humanoid alien who made a deal with Kevin.
Adidas Alien comes from an unknown dimension and carries a device with unknown powers that looks like an old laptop. He speaks through a voice synthesis program kinda like Stephen Hawking but less retarded. He wears Adidas which explains his name.
During episode 4 he promised to get Kevin a hotpuuh girlfriend if he kills all 9 moonshine masters whom he wants dead for some reason. He also gave Kevin an earpiece which allowed them to communicate, which however didn't work anymore after episode 4.
