Djinn

Djinn is a malevolent omnipotent being with a deep hatred of humanity.

Djinn was responsible for the eventual insanity of Armand St. John, allowing him to believe he had created a machine allowing him to pull parallel versions of himself from alternate universe. By the time that the USS Enterprise (NCC-1701) crew revealed this deception for what it was, Djinn destroyed the colony on Leora IV, claiming that they were close to a discovery that would allow humanity to evolve into a type of being with powers rivaling that of Djinn. Spock would later theorize that Djinn's hatred of humanity was simply the result of a realization that humanity would eventually surpass his race (TOS comic: All of Me).
