Slan

Slan is one of the villains of Berserk. She takes on the form of a succubus with black leathery wings and vine-like hair. She is a sadomasochist who thrives on cruelty and the effect it has on those who observe it. She appears to have a fascination with Guts when she manifests in the Qlippoth to confront him, having as well shown an interest in his incredible strength and survivability when the Count summoned the God Hand. Her name is borrowed from A. E. van Vogt's Slan.

Golden Age Arc
During the Eclipse, Slan along with the rest of the God Hand welcomes Griffith as one of them as he becomes Femto. Afterward, Slan watched as Casca is raped while Guts is forced to watch, she wept reveling in the "beauty" of the pain and misery of the Band of Hawk.

The Black Swordsman Arc
She appears when the God Hand is summoned by the Count in order to prevent his own impending death. Slan became interested in Guts when she saw Guts's determination to kill Griffith despite the pain of his brand from approaching the newly born God Hand. Slan expressed that it would be great if Guts could join them, but the others reminded her that his brand made that impossible.

Tower of Conviction Arc
During the Incarnation Ceremony, Slan, along with the other members of the God Hand, briefly manifested using the dead body of The Bubblehead (one of Mozgus' disciples) and several of the evil spirits that had gathered in order to witness Femto's rebirth.

Slan was also shown during the World Transformation.
