One of the two stone statues on Crossbone Island, it is an incarnation of darkness that was released from its seal by the "The Three of Dark" before Gandamu Daikotei. In order to cover the world in darkness, he sent his minions, the "The Three of Dark", to various places to search for the three "Nikidama" that are the counterparts of the "Arada". He also lent his power to evil people in various places and caused confusion in order to divert attention from the search for the "Arada." He possesses the Birmingham, the Evil Breaking Cannon, and the Bucket of Darkness, and can also summon the Evil Shadow Sword, which can be said to be the crystallization of evil hearts and darkness. In fact, the four Gundam Crystals split into Gandamu Daikotei
and Yamitaitei Gundam so that they could be reborn into one stronger being. If the people on earth had a strong sense of justice, Gandamu Daikotei would win, and if the people had a strong sense of evil, Yamitaitei Gundam would win.
