Riff Tamson/Legends

Riff Tamson was a Karkarodon male who served as a commander for the Confederacy of Independent Systems during the Clone Wars.

Biography
Around 21 BBY, following the assassination of King Yos Kolina of Mon Calamari and the subsequent Mon Calamari–Quarren tensions in the Calamari system, Tamson was sent as an envoy to the system, which was slowly falling to an advance by the Confederate Navy. The Galactic Republic responded by sending Jedi General Anakin Skywalker and Senator Padmé Amidala in an attempt to quell the tensions. But Tamson led a pre-emptive strike against the Mon Cals, and personally went after Prince Lee-Char, though the attack was temporarily driven off by Republic reinforcements. Tamson soon brought in Hydroid Medusa into the battle, driving the Republic forces deep into the underwater caves. He then turned to his Quarren allies, angry that they chose not to join the battle during his second strike. He personally warned the Nossor Ri not to disobey Count Dooku's orders again, otherwise he'd kill him on the spot.

As Tamson's forces gained control of the Calamari cities, Dooku ordered him to locate and kill the prince, so as to crush the morale of the Mon Cals. Tamson predicted that his quarry would attempt to reach the waiting Consular-class cruiser on the surface and had it destroyed just before they could reach it. He later received word that the long-ranged sensors had been destroyed, rendering the Separatists blind if any Republic reinforcements intend to arrive and rightly so, as Gungans are deployed from a Republic cruiser.

When Tamson was informed that the prince was spotted attempting to rally the hopes of his people, he decided to hunt the prince down personally. He deployed Trident-class assault ships to create whirlpools in order to confuse his enemies. Tamson then attempted to kill Lee-Char, but Jedi Kit Fisto and Ahsoka Tano stood in his defense. Eventually, Tamson had all the Jedi excluding Tano and Senators Amidala and Meena Tills captured, though the prince still eluded him.

Tamson attempted to kill Lee-Char as he killed Yos Kolina. After killing off many of Lee-Char's soldiers Tamson attempted to fight off Char head-on and Lee took one of his explosive knives Tamson wielded and threw it into his arm. Tamson swam towards the Prince in an attempt to kill him, but Lee-Char managed to destroy the bomb and Tamson before he got too close.

Personality and traits
An ambitious warlord, Tamson acted as an envoy for the Separatists on the aquatic planet Dac, perturbing political stability between the native Quarren and the Mon Calamari following the assassination of King Yos Kolina. Tamson rallied the Quarren and led a Separatist-backed attack on the Mon Cal, with the intention of deposing the unstable Galactic Republic-backed monarchy, now under the rule of Prince Lee-Char. Using genetically engineered hydroid medusas from his homeworld, Tamson conquered the Republic and Mon Cal armies with relative ease, and even personally forced the Jedi Master Kit Fisto into submission.
