Er, no. Why does everyone just assume this? I don't get it. :hmm: He likely died a simple death. Whatever the case, he's not a Stalfos.
Anyway:
The Hero's Shade is the ghost of the Hero of Time, NOT A STALFOS. Why do people assume he's a Stalfos? I don't know if there's anything mentioned in
Hyrule Historia which contradicts this, but I am pretty sure the Hero's Shade takes the form of the
golden wolf outside of the ghostly ether. His appearance to me is likely a "special case" as far a ghosts go, seeing as he's the Hero of Time and all -
with the mark of the Triforce and all that.
I guess I should provide a source now, huh? Well here's the best I could find
at the moment:
