Dave Filoni, executive producer of Star Wars Rebels, and Dee Bradley Baker, voice of the clone troopers, talk at length about the grizzled soldiers that Ahsoka Tano introduced to the Ghost crew.
In this clip from the Star Wars Rebels episode, "The Lost Commanders", Ezra introduces himself and the rest of his compatriots to the clones, who identify themselves as Captain Rex and Commanders Gregor and Wolffe. The meeting becomes much friendlier when Ezra reveals they were sent by Ahsoka Tano.
FALL OF THE REPUBLIC
Commander Wolffe served alongside Jedi General Plo Koon during the Clone Wars, forming his squad of clone troopers – nicknamed the Wolfpack -- into one of the most celebrated units in the Grand Army of the Republic.
The detail-focused Wolffe – who’d lost an eye in a close encounter with Asajj Ventress – had a sense of strategy superior to that of most clone officers, making him a highly effective complement to Plo.
Wolffe and his soldiers fought in many battles, but were also given missions away from the battlefield. They brought badly needed supplies to the devastated planet of Aleen and hunted Ahsoka Tano through Coruscant’s underlevels after her apparent betrayal of the Jedi Order.
THE DARK TIMES
Years after the Clone Wars, Wolffe hunted joopa on the plains of Seelos with his fellow clones Rex and Gregor. When Kanan Jarrus and his ghost crew showed up one day, Wolffe was the first to question the Jedi’s motives and even went so far as to contact the Empire. Rex was able to talk sense into the weary clone but it was too late. The Empire had sent a probe droid and discovered the crew’s whereabouts.
A Kel Dor from Dorin, Plo Koon was among the wisest members of the Jedi Order, respected for his level-headed analysis of events and unflappable calm. Deeply concerned for life in all its myriad forms, Plo was especially devoted to protecting the clones under his command. He shared a special bond with Ahsoka Tano, whom he’d brought to the Jedi Order as a toddler. One of many victims of Order 66, Master Plo died at Cato Neimoidia when his wingmen shot down his starfighter.
Eeth Koth was a member of the Jedi High Council in the final years of the order. From within the polished towers of the Jedi Temple on Coruscant, the Council governed the actions of the Jedi Knights. Koth was one of the 12 Jedi present when Qui-Gon Jinn presented Anakin Skywalker as the Chosen One to the Council. A determined warrior with a deep, spiritual connection to the Force, Koth resisted torture at the hands of General Grievous during the Clone Wars, and was even able to secretly communicate his location to the Jedi Council. Koth was saved from Separatist clutches by the daring efforts of his fellow Jedi.
A gargantuan heavy cruiser, the Malevolence is known for its immense ion cannons, which became a dire threat to the Republic fleet early in the Clone Wars. The cruiser's deadly two-step attack begins with knocking out the power systems of a target vessel with its primary weapon. Then the cruiser finishes off the defenseless spacecraft with blasts from its secondary laser cannons and turbolaser batteries.
C-3PO is a droid programmed for etiquette and protocol, built by the heroic Jedi Anakin Skywalker, and a constant companion to astromech R2-D2. Over the years, he was involved in some of the galaxy’s most defining moments and thrilling battles -- and is fluent in over six million forms of communication.
Ahsoka Tano, a Togruta female, was the Padawan learner to Anakin Skywalker and a hero of the Clone Wars. Alongside Anakin, she grew from headstrong student into a mature leader. But her destiny laid along a different path than the Jedi.
Clone Captain Rex served the Republic during the Clone Wars, often taking orders from Anakin Skywalker and Ahsoka Tano. He viewed military service as an honor, and he always completed his mission. Fond of using two blaster pistols at the same time, Rex customized his armor with distinctive blue markings. His loyalty to the Republic and his Jedi Generals was absolute, but even this dedicated veteran soldier found himself plagued by doubts as the Clone Wars claimed more lives and brought ruin to more worlds.
