(*)

(*) was a malevolent entity from another dimension. Approximately one million years ago, 0, with Q's assistance, used the Guardian of Forever to bring (*), The One, and Gorgan into the Universe. The group committed many atrocities, including the destruction of the T'Kon Empire. (TNG novel: Q-Strike)

After the Q Continuum banished 0, (*) hid himself, but continued to cause conflict and strife throughout the galaxy. In 2268, he attempted to start an eternal war between the crew of the USS Enterprise and the Klingons led by Kang, but was defeated by James T. Kirk. (TOS episode: Day of the Dove)
