So, taking into account how the Pokebeach leaks that talked about possible dual typed moves, as in getting STAB from one type and dealing damage as another.

The fact that the leaks said Fennekin's evo was Fire/Psy leads me to believe that Glow Punch might be the first revealed Dual type move, being Psy, but dealing damage as Fighting!

on a side note, there was a "leaker" that wrote that Fennekin gets a Psy move that is SE against Dark.
