Capcom and Mugen
As one of the top developers of fighting games the world over, capcom has inspired many creators to develop and reproduce their characters into M.U.G.E.N. Sprite rips of popular characters from games such as Marvel Vs Capcom and the Street Fighter Searies are easy to come by and tend to be first stop for new coders to try things (like the high number of Ryu, Ken, and Akuma edits)
The MvC style of gameplay and artwork are also very popular with mugen fans, and many characters and W.I.P's feature gameplay and artwork that simulate this style. Fans even go so far as to convert characters made by other companys, like Mortal Kombat to fit the MvC style.
