Fluttershy's father is the father of Fluttershy in Dragone Baby Gone that was brutally killed by his daughter. In an episode, Rarity was making a dress, then Pinkie's portal made him come back to life after Rarity mentions that "she could kill Fluttershy's father for more of those blue scales". It is unknown why Rarity made a dress with his "blue scales", because he does not have any blue on him.
