Zeus

Zeus the Thundercloud is a homie from Big Mom that she summom from her left hand. He is a special kind of homie, as he received a soul fragment from Big Mom herself, serving as one of her personal weapons alongside Prometheus and Napoleon.

During the escape from Totto Land, Zeus was captured by the Straw Hat Pirates and forced to become Nami's servant. He lived inside her Sorcery Clima-Tact until he was reclaimed by Big Mom in Wano Country.

However, Big Mom later abandoned Zeus for good after he struggled during the fighting on Onigashima, replacing him with another homie named Hera. Zeus then went back to Nami's ownership for good, with his soul currently inhabiting her Sorcery Clima-Tact.
