User blog comment:Thats cooper/Why do street fighter 1 characters not return/@comment-158.174.97.127-20191230051105

This reminds me of a similar blog a few years ago. But to answer your question, I believe it has to with gameplay/fighting style for the most part, Mike is covered by Balrog and Dudley, Geki by pretty much all the ninja fighters, Joe by Dee Jay (though in this case, since Joe appearently uses Savate now he is covered by Remy), Retsu by arguably Makoto, and Lee by Yun and Yang.
