Panthea was an acrobat in the Zombozo circus. She performed with the pixie gang, making use of her prehensile hair—which she can move around in independent bundles—to perform feats of gymnastics and agility. She is the twin sister of Meroe.
During the events of Revelry and Revenge, Panthea initially sided with her sister in a confrontation with the SPI agents, but was convinced to help her sister face justice for her crimes. Unfortunately, when the agents escaped on the Vondalstalk into the crystal flux, she and her sister became infected with some kind of wild magic disease, which began to erode them from the inside.
Panthea was held captive at SPI HQ for a short time until Military Aid and Defense agents showed up to eject them from the premises, at which point the SPI agents took Panthea and Meroe with them (Amalgamation and Anathema).
When the SPI then decided to assist Bonny Qin with a heist of the Cornucopia of Life, Panthea and Meroe joined them in the hope of drinking from the water to get cured (Capers and Calamity). While Panthea was ultimately able to drink from the water, she faced the judgment of Pelor, who struck her dead but declared her body and soul cleansed, and headed to a better place.
