Interesting take of the Fiend Character.
You can add Bray himself to the list since the Fiend was more of a return to what made Bray successful in his first run prior to his defeat to Cena at WM 30.
When you let the Fiend in you return to your true self.
The other easter egg that was found online (not sure if this has been validated) was that when The Fiend was fighting Cena, Rollins, Balor, and Miz (who he turned heel) he used his "hurt" gloved hand when he was pummeling them, and with Bryan (who turned face) he initially used his "heal" hand.
