Star Wars: The Force Unleashed (project)
After the "Unleashed" franchise was discontinued following Disney's decision to refresh the "Star Wars" canon in favor of producing a sequel trilogy, Sam Witwer, Marek's voice actor, revealed that Dave Filoni, the creator of the "Star Wars Rebels" animated series, considered bringing Marek back into the new canon and having him appear in that series, but ultimately decided against it because he could not find a way to do so without compromising either the new canon's quality or the character's unique distinctions.
List of Star Wars Rebels characters
Agent Alexsandr Kallus (voiced by David Oyelowo) is a former high-ranking agent of the Imperial Security Bureau and skilled rebel hunter, serving under Darth Vader and working with the Inquisitors. More often than not, he is able to recognize rebel traps and set his own, which nearly succeed in capturing the Lothal rebels. Kallus is present when the Empire massacre the Lasat homeworld of Lasan (Zeb's species) and personally gives the order to use soon-after banned disruptor weapons in the assault. It is later revealed that his hatred of Lasats stems from a harrowing encounter with a Lasat mercenary in his early ISB years, where he was the sole survivor of his unit. Despite his antipathy for the Lasats, Kallus respects them as warriors and in fact bears a degree of remorse over the fact that genocide was used to conquer Lasan. He is also a highly trained hand-to-hand combatant and carries a rare Lasat bo-rifle which was given to him by a Lasat Honor Guard he defeated in single combat when their homeworld fell to the Galactic Empire.
