About the Verse
M.U.G.E.N, also called MUGEN, is a fighting game that originally started out as a FPS engine, but (For reasons unknown) turned into a fighting game. It was created by Elecbyte, however, the innovative thing about M.U.G.E.N. is that the very own users create their own characters, stages and even Motifs. Because of that, technically all characters on fiction "exist" on M.U.G.E.N., although most are balanced.
Since M.U.G.E.N is a fighting game, where all characters on fiction are used on combat, it is absolutely impossible to scale characters to each other, except on very specific cases (Such as Ironcommando's 20000 and Mecha Scorpio). So, even characters that would be normally much below other characters might be able to beat them (Ex: SMB1 Mario beating Dormammu).
To explain the tier of each M.U.G.E.N character, one must consider their Hypers/Supers, the cutscene effects, and the few cases where they can be scaled. Also, note that only M.U.G.E.N originals are allowed on this wiki.
Power of the Verse
While most characters of this verse are quite weak, many of them sport crazy hax, and there are cases of incredible raw power.
