Gredora

She is the queen and "mother" of Megacolony, and considers all of the mutants and machines as her children. Her subordinate is Darkface, who was sent to Planet Earth before her to gather intelligence and blueprints. Although she is an Apostle, she has her own plan separate to that of Evil God Bishop, Gastille's. After the destruction caused by Dragon Deity of Destruction, Gyze, she plans on ruling the post-apocalyptic world. (Source: Cardfight!! Vanguard Wiki)
