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". Shortly after, Grey discovers the power of A-Trans after defeating the Pseudoroid, Buckfire (Diaburn in the Japanese version). Model A, though unsure of assisting Grey, decides to tag along for his own safety. He is then given an invitation by the Sage Trinity to visit Legion, the most powerful organization in the world in order to inspect Model A. During his venture, he encounters four other Mega Men, Aeolus, Atlas, Thetis and Siarnaq, who wields the Biometals, H, F, L and P, respectively. He firs fights against Atlas and manages to defeat her before she harvests the souls of a stray group of Raiders to Model W and in the process, breaks a cipher, revealing secret encoded data about the Model W. Grey then finally heads to Legion but is temporarily stopped short by Siarnaq, but is also defeated, resulting in another cipher, this time, showing a vague figured as well as a hint as to the creator of Model W, who appears to be one of the Sage Trinity. Though Model A is unsure at this point, Grey continues on ahead for the truth. The perpetrator appears to be none other than Albert, who is seen with several Model W fragments and escapes Grey's attack, but not before telling him he was 'made in his image'. Later on, he discovers that he was made as an "Alternate body" for Albert, who created Model A.
