About the AUEdit
In this AU, the Big Four are featured as characters in the show Pushing Daisies. In Pushing Daisies, a pie-maker named Ned has the mysterious ability to resurrect the dead through touch, who works with ace detective Emerson Cod to solve murder cases. Along the way, Ned uses his powers to resurrect his childhood friend Chuck as they solve her murder and slowly rekindle what they had.
In most cases, fanfic writers and artists have one of the characters have Ned's powers and other characters being people he has resurrected.
Most commonly, Hiccup is portrayed as the parallel to Ned, having the same awkward stance and undead powers as him.
In more than one instance, Jack is portrayed as a male version of Chuck, revived by the Ned-equivalent, his white hair being a trait either by dying it to remain inconspicuous or caused by his deceased state (through embalming or stress).
