EVIL SECTAURS OF THE DARK DOMAIN!
Meet SKULK, the Dark Domain's multi-eyed master of terror and mayhem! Abandoned as an infant, SKULK was raised by DEVORA, the Dark Domain's ruling empress. Sly and stealthy, SKULK prefers to operate from the shadows with his scuttling spider TRANCULA — a wriggling, hairy menace in the dark! Together, they pledge their vile allegiance to GENERAL SPIDRAX and his Dark Domain.
