Based on Metal slug's original protagonists in early prototype version game. https://www.deviantart.com/ragingbullet/art/Tails-and-Z... (You can go there by clicking one of two links in dA drawing description). Tails is cosplaying"Phil Gene" and zooey is cosplaying "Michiko Nakajima". Phil and Michiko are two regular army's engineers and the original metal slug pilots. I heard that prototype you were also going to have some of allies to aid your journey to stop morden's madness.
