Can't believe there isn't already a thread for this!
14 year old Danny Fenton lives in a house that pretty much exists to fight ghosts. After his friends, Tucker and Sam convince him to take a look inside his parent's Ghost portal, he gets shocked and his DNA merges with ghost ectoplasm, creating what is known in the Ghost Zone, a 'halfa'. Half-Ghost, Half-Human. Between his parent's crazed obsession with attacking ghosts to the ghosts that keep leaking out of the Ghost Zone, he's got his hands full! Add on top of that schoolwork and being the favorite punching-bag of local bully Dash Baxter, and it's a good thing (his sister) Jazz, Sam and Tucker are there to help!
Danny Phantom started in 2004, and had 3 seasons, cancelled midway through the 3rd and it concluded with a special, "Phantom Planet" in 2007, leaving many cliffhangers from previous episodes. Despite fans protests and efforts to keep Danny Phantom going, the series ended due to financial issues and Nickelodeon refusing to support it. Butch Hartman has stated that he is willing to make new episodes if the series picks up again, and that "People still love Danny". There is a rumor going around that it will pick up again in 2013.
