Harcesis
In the
science fiction television show
Stargate SG-1, a
Harcesis is a
Human child born off the hosts of two
Goa'uld mates when the hosts are still possessed. The Harcesis born thus would possess all the knowledge of the Goa'uld, and is generally considered an abomination for the same reason. It is also generally forbidden to create such a child.
Daniel Jackson's step-son
Shifu is a Harcesis - the only known. He is the son of
Apophis and
Sha're/
Amonet. Apophis fathered Shifu in the hope of taking over his body as a new host. However after his birth
Heru-ur planned to kidnap the child but instead Daniel gave the child in the care of Sha're's father
Kasuf. ("
Secrets")
Shifu then came to the planet Kheb and there the Ascended
Ancient Oma Desala started to take care of him. It turned out that Shifu was genetically engineered to age faster, so that he could be taken over more quickly by Apophis. However having the genetic memories of the parent Goa'uld, and in turn the generations of Goa'uld before them, would drive a being to madness. In the case of Shifu, Oma Desala taught him to forget, the only way to win the battle (for relative sanity) is to avoid engaging the battle. Later on, Shifu is shown to be an Ascended being himself. He made contact with
SG-1 and then showed Daniel a vision how this gigantic memory and the power which comes through it, can corrupt a person. He then disappeared and has not been seen since. ("
Absolute Power")
A few years later rogue agents of the
NID created Anna, a Goa'uld/Human hybrid, who can be considered very similar to a Harcesis child. However it is unknown if this hybrid has the knowledge of all Goa'uld but it appears not. ("
Resurrection")
The term "Harcesis" is likely derived from "
Harsiesis," meaning
Horus son of
Isis. Harsiesis was one of many names for
Horus.
