When Vlad Plasmius accidentally awakens the most powerful ghost of them all -- Pariah Dark, the King of all Ghosts -- Danny quickly finds himself the pawn in an action-packed, suspenseful game of chess. The only way to defeat the Ghost King seems to be a brand new Ecto-Skeleton battle suit that Jack and Maddie have constructed, but there's one big problem: wearing the suit can be fatal and only Danny can use it to defeat the Ghost King . With time running out, and the entire town of Amity Park sucked into the Ghost Zone, Danny Phantom must battle the all-powerful Ghost King to save his family, his friends, and even his enemies.
