Danny Fenton, is involved in an accident in his parent's Basement/Laboratory. Danny's parents, Jack and Maddie Fenton's construction of a 'Ghost portal', an artificial gateway into the 'ghost zone', where-in Danny, standing inside his parents 'ghost portal' when it activated, is infused with ectoplasm all the way down to Danny's molecular level--the end result is Danny's is rendered with a variety of 'ghost powers'.

The Ghost Zone coexists with the physical world, there mutual existence is interlinked; they are the proverbial 'flip-side-of-the-coin' to each other. The 'Ghost Zone' is a dimension composed of variations of ectoplasm where 'ghosts' exsist and through naturally occuring portals can cross-over into the human world, hoping to make a scene or one way or another take over mankind.
