Ultraman Eighty, or Ultraman 80 was a tokusatsu series, part of the Ultra Series that lasted from 1980-1981. The Japanese government discovers why giant monsters appear around the world--the monsters were created from the negative energies of hatred, racism, self-doubt, and anger. These negative energies manifested from the nightmares and selfish wishes of people and are "created" with malicious thoughts, giving credence to the monsters' "evil" natures.
