The Terraklons were a species with oval heads and fangs on the lower mouth. Their skin color ranged from green to purple. As the legs that they are seen to have appear to be mechanical, it is possible that they do not possess legs of their own. Lord Flint Vorselon was a notable member of the species. Their home planet, Terraklon Six, was destroyed during the events of Tools of Destruction, and all of the Terraklons imprisoned in Zordoom Prison were released. They were also known to inhabit the Terraklon Mines on Gribnak, and the gladiators used in the fight festival came from here.
Pre-Ratchet and Clank
The Terraklons were a violent, cunning and highly feared race in the Polaris Galaxy. At some point the Terraklons waged war against the Drophyds. Led by Flint Vorselon, the Terraklons invaded the Drophyd homeworld of Zaurik. Despite their efforts, the Drophyds defeated the Terraklons and left Flint Vorselon nothing but a disembodied head. The Drophyds soon enslaved the Terraklons, sending many to Zordoom Prison on planet Viceron and forcing countless others to be gladiators in Magnetum Tournament on planet Mukow for the Imperial Troops' entertainment.
Ratchet and Clank Future: Tools of Destruction
During the events of Ratchet & Clank Future: Tools of Destruction, Terraklon Six, the homeworld of the Terraklons, was destroyed in the Thyrullian supernova. The Terraklons, save for Lord Vorselon, were granted their freedom and the Terraklons became nomads as they searched the galaxy for a new world to call home.
Ratchet and Clank Future: Quest For Booty
The only known information about the Terraklons in Ratchet & Clank Future: Quest for Booty involves Lord Flint Vorselon. Lord Vorselon escaped Zordoom Prison sometime after the fall of the Imperial Army and began working as an assassin for hire. At some point he met Nefarious and was hired to be Nefarious's enforcer in the Breegus System. Using his own ship crewed by Nefarious Troopers, he enforced the Doctor's will throughout the system.
Ratchet & Clank Future: A Crack in Time
Again, the only known information about the Terraklons at this point involves Lord Vorselon. Vorselon attempted to track down Alister Azimuth per the orders of Dr. Nefarious. Three times he encountered Ratchet and was defeated, the final defeat bringing about his death.

Relationships with other races
Argonoids and Paladrones
The Terraklons, like many races, fear the Cragmites.
The Terraklons appear to have a deep hatred for the Drophyds. Despite their skill as warriors, the Terraklons were unable to defeat the Drophyds. It is likely that Lord Vorselon joined Nefarious not only to get his former body back but also change the past and assure that the Terraklons defeated the Drophyds on Zaurik.
The Terraklons have a hostile relationship with the Fongoids, as mentioned by Azimuth. What the exact cause for this relationship is unknown.
During battle, Lord Vorselon could be heard saying that Terraklons once feared Lombaxes. When training Ratchet with the Hoverboots, Azimuth mentions a battle he and Kaden fought against the Terraklons to free the Fongoids.
