Dathula

Dathula was a titan and a mythical warrior from, "a lost time". In 5,000 BBY, he and his fellow titans fought in a Great War against the Sith. However, Dathula and the titans lost the battle, and were banished as the Golden Age of the Sith began. Dathula was a prisoner on the planet Dathomir by a Nightsister for over 5,000 years. 5,033 years later, Dathula was discovered and freed by Darth Raiden during a huge battle on the planet between Darth Raiden's Sith and the New Jedi Order. Raiden and his army won the battle, and he killed the Nightsister that was keeping Dathula hostage. The titan then joined Raiden and his Sith minions. Together, they planned to destroy all of the Jedi and extinguish all of the light once and for all.
