Triceraton Empire

The Triceraton Empire is the militant governing empire of the remaining Triceratons left alive after their home planet was destroyed.

1987
The Triceratons appear as villainous invaders on the original TMNT show in the episode "Night of the Dark Turtle", under the command of a Captain Zorax; their government is called the Triceraton Empire".

Upon their arrival on Earth, they tried to transport the planet through a stargate to their homeworlds in order to plunder it completely, but this plan was thwarted by Donatello, who lead them to believe that he and his brothers were far superior to the Triceratons powers and abilities causing them to leave Earth.

The Triceraton Republic was a glorious empire whose warriors were following a strict code of honor. But when Prime Leader Zanramon took over, the Republic soon began to regress into a dictatorship, with few warriors left to follow the true path of honor.

To level the scales against their hated enemies, the Triceratons looked for Professor Honeycutt, who had developed a teleportal, a device that could instantaneously transport anything across the universe and had the potential to be one of the most useful weapons in the universe. Like the Federation, the Triceratons planned to use the device to defeat the former. They captured the professor thanks to a Federation collaborator, then tried to promise Honeycutt protection if he built his device - he refused, but the deal changed when he recognized his four Turtle friends whom they also captured (and who had accidentally been transmatted to the Federation’s galaxy), who had followed him and were now threatened with death if Honeycutt refused. When he was still reluctant the threat got even bigger when the Turtles were put in Their gladiator Games, but they managed to escape, taking Zanramon hostage so as to secure their escape aboard his personal cruiser. However the Triceratons pursued them, the Triceratons soon battled against the Federation who had arrived to take custody of the escaped Fugitoid. But Honeycutt and the Turtles escaped with a transmat beam sent by the Utroms.

The Triceratons soon tracked the transmat beam from Earth and began invading to find out where Honeycutt was, but the United Nations had no idea what they were talking about. It was soon apparent that Honeycutt was not on the planet, as they could not trace his positronic signature anywhere on the planet, so they left, but they shortly came back when Honeycutt returned from the Utrom homeworld to surrender himself to the warring parties. This lead to a wide goose chase around New York City, with the Turtles doing their best to keep the Professor out of the Triceratons' hands. The Triceratons were soon ambushed by a waiting Federation fleet, who were allied with the Earth Protection Force. Honeycutt soon disabled the Fed ships, so Zanramon ordered them destroyed. Mozar refused to and assisted in the coup d'état led by Traximus to overthrow him. The republican system was reinstated and the Triceratons made the first move towards a lasting peace with the Federation. Zanramon and Blanque were last seen in neighboring cells.

2012
Prior to the start of the TMNT 2012 series, for one thousand years, the Triceratons and the Kraang have fought over Dimension X. The Kraang used their intelligence to battle, while the Triceratons relied on brute strength and cunning. It seemed the Triceratons would win, but the Kraang used the most powerful weapon in the universe: a black-hole generator that wiped out the Triceraton's whole planet. Only a single Triceraton fleet survived, and they vowed vengeance. Over time the empire got bigger, carried more destructive firepower, found the Heart of Darkness, and resumed their quest to find and exterminate the Kraang. The Triceraton Empire activate the Heart of Darkness that ends up destroying Earth.

The Triceratons were all destroyed when the Fugitoid combines the dark matter of the Ulixes' power core with the fusion energy of his own power core, creating a cataclysmic explosion that engulfs the mothership, the Ulixes, and the Heart of Darkness, destroying all of them, and wiping out Mozar and all of his troops in one fall swoop.
