Grey

Grey (グレイ) is one of the playable characters in Mega Man ZX Advent. He first appears within stasis in the Mysterious Lab, and is awakened by a battle between Hunters and Galleons, not knowing who he was or anything about his world. Pandora finds him and proclaims him as "Defective", explaining that she has to kill him. However, he grabs a gun from a fallen Hunter, fires on her, and escapes. He is knocked out while fighting Dogu the Giant, and is found by the Hunter Billy, who takes him to Hunter Camp, where he is given a Hunter's License and asked to help escort the Model A Biometal to Legion. However, Prometheus and Pandora attack the train carrying it, and the Biometal responds to Grey. They Megamerge, and the pair allows him to join the "Game of Destiny". Later on, he discovers that he was made as an "Alternate body" for Albert, who created Model A.
