Tyrant

Tyrant is a fictional, extraterrestrial supervillain in comic books published by Marvel Comics. The character first appears in Silver Surfer vol. 3, #81 (June 1993).

In the distant past, the devourer of worlds, Galactus, created an immensely powerful living machine in his own image, and bestowed upon it the power cosmic: Tyrant. However, unlike his creator, Tyrant developed a lust for tyranny and conquest that directly conflicted with Galactus' desire to do only what is necessary to survive. Tyrant's conquests aroused opposition in many forms including an order of super-powered female warriors called the Spinsterhood, of which Ganymede was a member.

Eventually, Galactus learned of Tyrant's betrayal and engaged him in a titanic battle that unleashed energies that (according to Thanos) had destroyed whole galaxies.

In the end, Galactus defeated Tyrant, stripped him of the bulk of his power (thereby reducing him to his current stature and power levels), and banished him to the farthest corners of the universe. The Spinsters mistakenly believed they were responsible for driving Tyrant away, when in fact it was his defeat and depowerment at the hands of Galactus that had done so, as Ganymede later learned.
