It said that Blast was an active hero 15 years before the start of the association, but I haven't seen the obvious answer in these replies. It's kind of funny to think of a time traveling Saitama, but lets be real here. It's probably just Saitama's dad or older brother. We know literally nothing abou his familiy so it is possible.
