Actually I just found out that in Hyrule Historia it proves the hero shade is the hero of time from Oot, who never made it back from terminia. so thats the answer, the mods should close this thread soon...
The WW is on a seperate part of the timeline than tp,I like to think maybe shade is link from MM.Thats assuming he became a stalfos which is why he never came back from terminia.Though there is no proof of this theory being a fact.
