Gator Tooth Wiki

Arachne is a Spider Girl and occurring villain of the Ghost series. She tried to brainwash Casey into being her boyfriend and kill Penelope.


Arachne is taunting, selfish and arrogant. She is very lethal and has abilities of a Black-Widow Spider, capable of injecting mind-control venom into the bloodstream and form her own army of mind-controlled henchmen.
