the end of the tenrojima arc. I'm talking about the moment when Acnologia and fairy tail fight. then the moment where they realize they can't win. then the part where they all hold hands and Acnologia just sinks the island. and u see everyone from zeref to the council watching this happen powerlessly. it's also in this moment we see dragons are around and we see Gildarts the strongest wizard be fearful. this moment changed the show and was amazing.
