Powers and abilities
Created In his masters image, Tyrant has the same powers and abilities as Galactus and to virtually the same extent and power.
Tyrant possessed enormous cosmic power. He could absorb and channel a tremendous amount of cosmic energy for destructive purposes. He possessed vast indeterminable levels of superhuman strength, and was incredibly resistant to physical injuries. Being of bio-mechanical properties, Tyrant was effectively immortal. Tyrant also had the ability to psionically control any technology that he came into contact with at will. Tyrant proved capable of turning even the world ship of Galactus against it's master.
In his original form, Tyrant was as large as Galactus and nearly as powerful. After Tyrant's eventual defeat and depowerement at the hands of Galactus eons ago he was reduced to his lesser modern state. When Tyrant was last seen he drew on the energy of planetary biospheres and proved capable of feeding on the energy blasts of a starved Galactus.
In his diminished form Tyrant's power was initially portrayed as dependent on feeding from containers of superhuman energy, and directly proportional to the amount he had available. When he wasn't at full power, he proved capable of defeating an alliance of super-powered beings which included Silver Surfer, Morg, Terrax, Beta Ray Bill, Gladiator, Ganymede, and Jack of Hearts.
When temporarily denied access to his containers, Terrax, Ganymede, and Jack of Hearts alone managed to keep Tyrant busy for a period of time, and Thanos managed to barely fight him to a standstill through empowering himself by using one of them.
In addition, Tyrant commanded a number of robots who proved powerful enough to incapacitate the likes of Gladiator and Morg. His Fortress had equipment capable of draining and storing the life forces of living beings to power his robots and Fortress.
Tyrant whoops them all.
