Dagan had his little empire in Prometheus labs. Then a Houdini accidentally teleports him to Equestria, pissing him off to no end. Clad in his Alpha-Daddy style suit, he captures a 'Little Sister' called Scootaloo and decides to 'Harvest the ADAM' of Ponyville.

Its a story about a Splicer in Equestria, inspired/based on the Minion of Ares and that other big daddy story that I can't remember.
