Mokko was a male gang boss who operated in Mokkotown on the desert planet Ipsidon during the start of the Imperial Era.
Mokko would give food to his "top earner," and gave a small ration of food to the rest of his workers, including Benni Baro. However, having a gluttonous appetite, Mokko kept most of the food for himself without his workers knowing.
After his manipulation of his workers was outed by Benni Baro, Mokko was confronted by his workers and Clone Force 99. The standoff ended in Mokko's death as he fell from a walkway over molten ipsium, during which he attempted to pull Benni down with him when he offered his hand. Ultimately, the workers came together and saved Benni, leaving Mokko to die alone.
