Yeah, it was an Onimusha fighting game spin-off. Zero & MegaMan.exe both had stages even, Exe had the Cyber Net and Zero had a ruined MMZ-esque skyscraper. I agree that Zero needs to be in a new one. I have an edited SVC Zero, as well as the original, in my MUGEN game with a more MMZ gameplay style moveset. I also have MegaMan, Roll, & Tron Bonne from MvC2, Bass, Protoman, Cutman, & X based on MegaMan's MvC2 sprites & moveset, an original MegaMan X, an original MegaMan.exe, an original MMX style Zero based on his X4 moveset, a MegaMan 8 Yellow Devil, an original Mettaur, all MMZ humanoid reploid bosses, including Omega Zero & Copy X in their in-game style, Vent, Aile, and Giro in their in-game styles, and Bass.exe in his in-game style.
