Zaka is the Darcsen tank commander of Squad 7. As a Darcsen from the Vi'iikiye Universe, he has had to become used to many racial insults that are thrown at him. Zaka was held in an Imperial work camp where he and his people were forced to work in the dangerous Ragnite mines and factories under brutal conditions imposed by Gregor. He was instrumental in helping AGV in a Dantooine raid in the Viau Universe as an inside contact and joined the group shortly after the battle.
Despite his somewhat intimidating appearance, Zaka is a very kind and gentle person; when Irene Ellet calls him a "grizzly bear", Zaka replies that he would rather think of himself as a "teddy bear." He is very good with children, and would frequently take care of orphans while imprisoned in the concentration camp. He sympathises with the militia and is very civil and patient with all the members of Squad 7, even the Darcsen-hating Rosie. He seems rather amused by Welkin's nature obsession, and even chuckles when he hears him compare humans to beetles, stating that was the first time he had ever heard someone compare humans to insects in a good way before (referring to Gregor calling Darcsens "maggots").
Zaka is generally a pacifist, stating that it's the Darcsen way to not respond to situations with violence, even if it leads to their deaths, and if they die, they die for peace. He also rejects the concept of revenge, believing that it accomplishes nothing but more deaths. However, while he doesn't believe in violence, he is willing to resort to it if it's the only option open to him; this is proven during the Fouzen operation, where he devises a plan to destroy the bridge in which Gregor's armoured train is situated in order to kill him, albeit indirectly. Before the operation, he states that he has been waiting for this day for a long time, suggesting a deep hatred for the man. Afterwards, he joins Squad 7 as a Gallian militiaman, telling Welkin that he admires him for his "fresh perspective."
Zaka cares a great deal for his fellow Darcsens, with all of his favourite people in Squad 7 being such. Although they didn't know each other for very long, Zaka and Isara formed a strong bond very quickly, due to the fact that they are both Darcsens, and so can easily relate to each other due to the prejudice they suffer. Zaka knows full well that the world is not kind to Darcsens and so can sympathise with people's desires to just look away. Nevertheless, he believes that it's better to face the truth, stating it makes people stronger. Much like Isara, he hopes for the day where Darcsens will be treated as equals again, and believes it is up to them to change people's minds. When working alongside the Allies who hold no descrimination towards his people and more friendlier, beiving the world could learn from them and also sympathetic to other races who share such treatment such as the Quarians, Twi'leks and Edanians which made him bond with many.
