Hades’s skulls shoulder piece worn by Erik Thomson in the episode “Mortal Beloved” from season 1. This shoulder piece was only seen once in the series in this episode.
This shoulder piece is made of black leather and resin detailed skulls on each shoulder. The piece has an inner label written “Hades” so there is no doubt that was used by the God of the underworld. Also it has two holes on each side where used to be attached the velvet cape.
I already have two different Hades costumes so this is the third costume-piece I got.
