Origin

Tyrant was created by Galactus eons ago, yet their conflicting styles tore them apart. Galactus is a minimalist, doing his best to survive, knowing that if he feasts on the universe, he'll soon starve to death. Tyrant, on the other hand, simply lived for bloody war after bloody war, to fuel any conquest.

Exile

Galactus soon learned of Tyrant's wars, and found them a gross violation of the powers that Galactus had trusted to Tyrant. This caused a battle of epic proportions, and the master, Galactus, won.

Tyrant was both exiled, and deprived of his powers of being a Heralds of Galactus. He was still a powerful being, just not able to single-handedly take on planets anymore.

Story Lines

Once Tyrant kidnapped a variety of different space-faring heroes and villains in order to use their combined powers to enhance himself. These kidnapped beings included Silver Surfer, Terrax, Morg, Beta Ray Bill, Gladiator, Captain Marvel, Jack Of Hearts, and Ganymede. Jack of Hearts, the last of the beings to have been captured, managed to destroy his containment unit before he could be placed into it, rendering him unconscious for the remainder of the following battle but allowing the others to go free. Tyrant defeated all of them, appearing to "toy" with them in the process.

At the conflicts conclusion, Galactus himself arrived, looking for Morg, his current herald. Galactus' arrival disrupted the battle so Tyrant made the decision to offer all the others' freedom to Galactus in exchange for Morg. Galactus reluctantly accepted Tyrant's offer.

The megalomaniac Thanos, needing to prove himself, teamed up with the likes of Terrax, Ganymede and Captain Marvel. After the battle started, Thanos drifted away through Tyrant's fortress, and learned of Tyrant's past, of being Galactus's herald.

Allies defeated, Thanos approached Tyrant, and challenged him to a duel. Using one of Tyrant's power orbs, Thanos was barely able to sustain the battle, yet had to soon teleport away, having obtained the power orb he sought and proving he can stand against Tyrant.

Death

Tyrant was later destroyed when Morg used the Ultimate Nullifier on Galactus' ship killing everyone aboard it.

Powers

Tyrant possessed nearly unlimited cosmic power, he was second only to Galactus. He was able to battle, and defeat, an group of super-powered beings which included:

In Tyrant's original form he was as huge as Galactus and almost as powerful, but after his loss and depowerment at the hands of his creator Galactus eons ago he was reduced to a lesser modern state. When Tyrant was seen last he drew on the energy of planetary biospheres; every planet that Galactus consumed would leave Tyrant weaker.

Tyrant also has total psionic control over all technology, allowing him to bend any machinery he came into contact with to his own will.

Tyrant commanded a seemingly limitless number of robots who were powerful enough to incapacitate the likes of the Gladiator and Morg. Also, his fortress had equipment with the ability to drain and store the life force of living beings to power his robots and his fortress.
