Lol, today was horror. I had to wait in the car for like almost three hours...so I kinda decided to draw my attention to this as much as possible. Fierce Deity Link is only typically seen in Majora's Mask, Hyrule Warriors, Breath of the Wild, and is referenced in Triforce Heros. A lot of theories have gone around, and I think it's more than a theory. The FD Mask is obviously much more powerful than Majora's Mask itself..that being said a lot believe it can lose control just as much. Due to Link's courageous heart, however, he's able to control it. Buuuut- it doesn't hurt to bring out something where he kinda loses it from time to time. I like suspense and drama in my games, rp's and movies, so it's honestly interesting for me.
