An upcoming animation sequel, based on Madness Combat and My Little Pony: Friendship is Magic crossroad. They appear to be very close enemies, in which they are featured fighting, called A.A.P. VS MLP. It hasn't got any release date or month, not even a season (maybe spring).
Sit tight bronies and pegasisters...and stay tuned to watch your favourite characters fighting men from Nevada, who appear to be inhabitants and lovers of unreality and MADNESS!
