gear 4 was expected seeing how since the timeskip luffy was able to use gear 2nd or 3rd on a whim like that. remember he had to go in that stance to activate gear 2nd... no its just "red hawk" on "red hawl" off and an instant elephant gun too. The other gears are like normal attacks to luffy now so gear 4 is gonna be his new all out mode so to speak
