Monster Hunter Stories was released recently for the Nintendo 3DS on 9/8/2017, and they already have some Zelda DLC that will be released tomorrow (9/28/2017). I don’t know much about the Monster Hunter franchise as I have yet to play a game, but from the short trailer posted on Nintendo’s Youtube channel, it appears that the DLC will feature the characters Link, Epona, and Skull Kid (or just Majora’s Mask). You will be able to fight with both Epona and Link and there will also be fishing! To me, it appears that Skull Kid (or Majora’s Mask) will be some kind of sidekick to Link.
