Pakki was originally a space monkey owned by Alien Monoron. At first it looked similar to a monkey from Earth but due to the difference of the environment between it's homeworld and the Earth; it then grew up to abnormal size and then attacked the village of Okutama, striking at houses and burning them with his flames. Fortunately, the Mighty Jack was able to takedown and defeat Pakk with their fighter planes, firing their missiles against him. Eventually, Pakki was set into flames and then collapsed, finally ending the beast's brief reign of terror.


  • According to Master of Monsters, Pakki was constructed for the Ultra Garrison, a proposed Tokusatsu series predating Ultraseven, about a family of Cavemen.
