Spectra Vondergeist (originally trademarked as "Spectra Von Hauntington) is a fictional character in the Monster High franchise. She is the daughter of the ghosts, and is 16 in monster years, the same age as Ghoulia Yelps. She is voiced by Erin Fitzgerald. Her fashion motif is chains, balls and handcuffs. She has a pet ferret by the name of Rhuen.
She is mysterious, clueless and loves gossip. Through her indulgence in the latter she has started and keeps posting on a blog known as "Ghostly Gossip", though it is notorious for giving others the wrong impressions of what she sees and hears As she is prone to jump to conclusions, this leaves her blog muddying the lines between what is rumor and what is really occurring.
While her history - presumably in a former, human life - was quite tragic (though not revealed to the viewer), she has failed to move on, forcing her to remain a ghost. To cope she has constructed an elaborate and fanciful, albeit mysterious, false history about herself, which she has begun to even convince herself to it being true.
