Like i said, that's one idea. Perhaps they could make him a character. I just don't know what they could do.
Good point. I completely forgot about SR.
I also think that question could be answered with another question.
Would "relevant" characters be safe and uninteresting?
Because, imo, the best thing about smash is it's ability to revive dead franchises, or cast the spotlight on smaller franchises. Mega Man, Little Mac, Duck Hunt Duo, Shulk, Marth, Ness, Captain Falcon, Pit have all become much more well known because of smash and their franchises benefited.
