The accident happened when danny was 8 and got transported into the ghost zone then the portal exploded trapping danny in the ghost zone His parent quit ghost hunting after that but they still build there ecto-weapons to occupy themselves 9 years later danny returns to Amity park but it's not the same danny everyone remembers (Chapters may be short since I'm not the best when it comes to long plots I more of just come up with idea's) ART DOES NOT BELONG TO ME UNLESS SAID OTHERWISE!! DANNY PHANTOM DOESN'T BELONG TO ME!!
