Skull (スカール Sukāru), referred to as Scar in the Tokyopop English translation, is the top commander of the Black Ghost organization and the first major antagonist of the Cyborg 009 manga.
True to his name, Skull's uniform motif is based off of that of a skeleton, with him wearing a black skull-shaped helmet and his black bodysuit employing a ribcage-like pattern in the center.
He wears a long black cape, with a red interior. The yellow lenses of his skull helmet are reflective, and are often shown mirroring the images of whatever he sees as a visual effect (such as 009).
Skull's helmet and uniform change over the course of his appearances, due to Ishinomori's art evolution, though some theorize it can also signify changes within the character.
Skull is a sadistic, domineering, yet cryptic figure who only exists to bring about world domination and war, and along with those he serves under, exists as a figure that represents the evils in mankind, including their greed and willing to cause disaster for gain.
As part of the 00 cyborg project, he specifically orders his operatives to abduct whatever people they can find, making sure that they look for solitary subjects or ones that would leave the least questions if they were to disappear.
But even as a prevalent villain, Skull remains behind the scenes for most of the early manga, only resurfacing for his ultimate plans in domination.
By the time of his reappearance in the Yomi arc, Skull is revealed to indeed be a cyborg, but modified to the point where he can survive with his head and arms detached from his body, as no organic parts seem to remain in him at all. Before said body parts are detached, he displays the ability to spew acid from his mouth and can change his arms into a pair of spears.
Skull is only ultimately killed when the brains of Black Ghost melt him down with a laser for failing to defeat 009.
- A skull-themed character would later be used in Ishinomori's series The Skull Man, and a 2007 anime adaptation of the concept would bring things full-circle by having its own Skull Man become the head of Black Ghost at the end, as a shout-out to 009 and other Ishinomori works.
