Pucrates was originally a member of Barban, but was betrayed and swore revenge as he became a wild card in the Gingaman series.
Having taught Zahab the secrets of immortality through the soul jewels, Pucrates became a member of the pirate's crew alongside his niece Iliess prior to being sealed. Once released, Pucrates supported Iliess to be the first acting general before Sambash is named. Regardless, Pucrates provided Sambash with aid in formulating his schemes before he died in battle with Budoh becoming the new acting general and not needing Pucrates's assistance. Offended and humiliated, Pucrates schemed with Iliess to discredit Budoh so his niece can become the new general. Though Zaihab learned of their treachery, he allowed them to believed they got away with it until Iliess died fighting the Gingaman. Mortally wounded by Zahab to be kept him from resurrecting Iliess as her soul gem is used to revive Daitanix, Pucrates is tossed overboard with his shackles dragging him to the bottom of the sea.
However, Pucrates escaped his fate and vowed revenge on the Barban. To that end, he forced the Black Knight Hyuuga into his services to condition him into using the Knight Axe that can destroy Zahab. However, Pucrates is not able to live long enough to see his plan succeed as he is forced to sacrifice himself to hinder his former ally Shelinda from interfering.
