Tharpods are a native to planet Magnus from the Polaris Galaxy, featured in All 4 One, Ratchet & Clank (2016 game), and the movie. They are a peaceful race which worship nature and their pet critters. When Ratchet, Clank, Captain Qwark, and Dr. Nefarious arrived on the planet, they were a tribal, non-spacefaring race, though they had been technologically advanced prior to the rise of the minions, who stole their cities and forced them to live in small towns, prone to being thrown out by Creature Collectors at any time.
Ratchet & Clank re-imagined
Tharpods appear in the Solana Galaxy only in Qwark's version of events and the holo-film based on them. In these accounts, tharpods are found as citizens throughout planets Veldin, Kerwan, and Pokitaru, as well as in the audience for hoverboard racing on planets Rilgar and Kalebo III. The only notable tharpod character is Mr. Micron, an elderly tharpod who orders his ship to be fixed at Grim's garage, only for Ratchet to install unnecessary modifications including Mag Boosters that cause him to demand a refund.
Tharpods have never been seen living in Solana in canonical accounts of the franchise.
Pre-All 4 One
The tharpods lived on Magnus in relative peace with nature, caring for the critters. However, according to Dr. Croid, their relationship with a number of critters allowed the loki to use them to advance the tharpods for the loki's benefit in restoring their race. They had at become recent spacefarers, barely able to reach the Phonica Moon orbiting Magnus. The tharpods appeared to have limited contact with other races, apparently meeting GrummelNet.
Following the Ephemeris raid on Uzo City, the tharpods became nomads on their own homeworld, losing much of their civilization, and many struggling to survive. Remnants of tharpods that survived the raids lived in primitive camps, some of them, such as Susie, instead savotaged Collector bases. Often, they mustered around as Collectors made room for more animal preserve.
One tharpod, Dr. Croid, managed to hold out and resist Collector forces, and as such, the Phonica Moon and Terawatt Forest were under his control.
All 4 One
When Ratchet, Clank, Qwark, and Nefarious arrived on the planet, Susie was the first tharpod they interacted with.
Tharpods are an amphibian, turtle-like species with large shells covering most of their small body. They are otherwise bipedal humanoids, with their arms, legs, and neck poking out from their shell. Tharpods come in many different colors on their shells and skin, with common colors being green, blue, and purple, while their shells have lightly colored highlights.
Tharpods appear to have long lifespans, as Dr. Croid had worked over 100 years on destroying Ephemeris.
