The Karkarodon, a shark-like, amphibious-aquatic humanoid species that was native to the ocean world of Karkaris, were known to be fast swimmers and fierce hunters, capable of ripping-apart their enemies or their prey with their teeth. The Karkarodon Riff Tamson was a commander in the Confederacy of Independent Systems, and briefly was ruler of Mon Cala before Lee-Char overthrew and killed him. A Karkarodon was also imprisoned in the Republic Judiciary Central Detention Center around 20 BBY.
Karkarodons had webbed hands
Karkarodons were an aquatic species with sharp teeth and webbed hands and feet. They were fast swimmers and could rip-apart their prey or enemies with their teeth. Though they periodically lost their teeth, Karkarodons also rapidly regrew them. They swam with their legs crossed, resembling a shark's vertical tailfin. They were notably resilient; commander Riff Tamson managed two blaster shots to the chest without showing any signs of injury. The species was most comfortable in salty marine water, and preferred to be immersed in the liquid. They hailed from Karkaris, an oceanic planet which neighbored the Mon Calamari system.
The Karkarodon Riff Tamson led the Separatist invasion of Mon Cala
At some point, the Karkarodons created a cybernetically enhanced biological weapon known as the Hydroid Medusa, on Karkaris. During the Clone Wars, the Karkarodon commander Riff Tamson was sent by Count Dooku to help occupy the planet Mon Cala for the Confederacy of Independent Systems. After capturing the planet and its prince, Lee-Char, he declared himself ruler of the Mon Cala, having Karkarodon enforcers occupy the capital. His rule was short lived, however, when the Quarren senator Nossor Ri rebelled against him. Lee-Char was able to kill Tamson shortly after. A Karkarodon was among the many prisoners detained in the Republic Judiciary Central Detention Center. One day, he confronted the Jedi Master Obi-Wan Kenobi, disguised as bounty hunter Rako Hardeen, who responded by stabbing the Karkarodon's hand with a fork, threatening to eat him. He then let him go, and the Karkarodon fled back to his table.
The appearance of the Karkarodon is based on real-world sharks. Their name was also derived from the genus of the great white shark, Carcharodon.
