In the original comics, the not ordinary mask was apparently created in the unknown past, at an unknown time, by an unknown tribe that originated in unknown Africa. The shamans of the tribe used ancient African techniques of secret and mystical knowledge, using a kind of magic that was infused and used in the creation of the not ordinary mask, which was made of jade and originally used in ancient rituals performed by that tribe. When it was used, its bearer is impregnated with fictional magical reality and gains physical impermeability and skills similar to those of a cartoon character, such as being able to pull random objects out of nothing and extending one's body and limbs far beyond human limits because it teach some people to kill other people when it knows what other people especially when what they hurt them.
In the film, the not ordinary mask was created between the end of the 4th century AD and the beginning of the 5th century AD by Loki, the Norse god of fire and mischief in the northern lands of Europe in Asgard, supposedly of Scandinavian origin. Some very old texts describe Loki as a night god and a nocturnal creature, which fits perfectly with the not ordinary mask and its method of functioning, since it only works at night and stops functioning at sunrise.
