Sabertronian

The Sabretronians are the arch-nemesis of the Deathrons, hailing from the planet Sabertron. A generally heroic, honorable group, they tend to be dedicated to peace, and feel a need to protect other races from the Deathrons.

History
Sabretronians were the descendants of a line of robots created as consumer goods by the Trikatons on the planet Saibertron. Their bodies were forged by the Plasma Energy Chamber and given intelligence by the mega-computer Omni Seth in order for the work to be carried out. Eventually, they developed sentience and rebelled against their creators. The resistance leader, AXE-3 returned to turn the tide by activating his coda-remote which deactivated the Trikatons' Dark Guardian Robots.

With the Trikatons cast off and forgotten, Saibertron was at peace. The consumer goods and military hardware bots renamed themselves as Sabretronians and Deathrons. However, the Deathrons wanted war. No match for the superior firepower and battle prowess of the Deathrons, the Sabretronians developed transformation technology (possibly with the help of the Dark Guardians) to win the war, bringing about the Golden Age of Saibertron. Eventually, the Deathrons also developed transformation and began the third Saibertronian War. They would have succeeded in completing their conquest had not more time-displaced Sabretronians blown up an energy warehouse and brought its workers to AXE-3, now renamed Alpha One, as the new defenders of Saibertron.

By the Canopus year 2010 AGW, however, the Deathrons had succeeded in completely conquering Sabretron, but the attack by the Trikatons, coupled with the temporary loss of Megadrone (a reconstructed Violator) in that same year shattered their forces, allowing the Sabretronians to reclaim their home planet and rout their foes.
