Hollow
Hollow was a Sithspawn created by Darth Gloed. It was noted as being entirely ruthless, very powerful, and almost mindless, very much like its creator. It also had a distinct hole in its chest, hence its name.
Behind the scenes[]
Hollow is portrayed by Ichigo Kurosaki's outer hollow form from the anime/manga Bleach. Hollows are also some of the main antagonists of Bleach.
