With the return of the seventh and final season of The Clone Wars, interest in the show has been renewed and rekindled. The first arc of the show focuses on the Bad Batch and them teaming up with Rex and Anakin Skywalker to retrieve Echo.
In the first three episodes of the arc, one of the main antagonists is Wat Tambor. He’s a character many probably recognize, but that may be about it – leaving many wondering, “who is that guy?”
Put simply, Wat Tambor is the foreman of the Techno Union.
In this role as the head of the powerful and influential commerce guild, Tambor secretly aligned with Count Dooku, gaining him a seat on the Separatist Council. The Techno Union sought to keep this affiliation a secret, however, and maintained their neutrality throughout the war. All the while, Tambor’s guild produced millions of battle droids for the Separatist war effort. He was present for the meeting of the Separatist Council on Geonosis, seen in Attack of the Clones, and very shortly afterward the Clone Wars began.
Because of his prominent position within the Confederacy of Independent Systems, Tambor was tasked with overseeing the invasion of Ryloth early in the war. The Separatists took control of the planet’s capital, with Tambor established as ruler. In the first season of The Clone Wars, we see the Republic offensive attempting to liberate Ryloth, with Jedi Generals Mace Windu, Obi-Wan Kenobi, and Anakin Skywalker enlisting the help of Cham Syndulla the local freedom fighters to re-take the capital. While Count Dooku ordered Tambor to retreat, the latter refused until all of his treasures could be loaded into his ship. This plan backfired on him, and he was apprehended by Windu. Tambor surrendered unconditionally, and he was imprisoned.
Though we don’t know how it happened, at some point after the trial of Ahsoka Tano Tambor was freed from the Republic prison and immediately re-joined the Separatist leadership. He acquired the clone trooper Echo, who had been presumed dead at the Citadel, and used him to configure an algorithm that aided the Separatist war effort. This algorithm proved incredibly successful at predicting Republic tactics – and, in fact, it was almost too successful, as clone captain Rex grew suspicious. He enlisted the help of Anakin Skywalker and the Bad Batch to travel to Tambor’s homeworld of Skako Minor, where Echo was being held in a Techno Union facility. The Republic forces freed Echo and fled from Tambor and his decimator.
That mission to Skako Minor helped turn the tide of the Republic’s efforts on Anaxes, which took place during the Outer Rim Sieges near the end of the war. So it wasn’t long after that Tambor and the rest of the Separatist Council were sent to Utapau. Following the death of Count Dooku, however, General Grievous moved the Council to Mustafar. Both Utapau and Mustafar were worlds aligned with the Techno Union.
While on Mustafar, the Separatist Council was informed by Darth Sidious that Darth Vader would soon arrive and give them instructions on what to do next; however, upon Vader’s arrival, the Separatist Council was executed. Tambor attempted to hide out in a meeting room, but he could not escape the blade of Darth Vader.
