A new TV commercial for The Legend of Zelda: Breath of the Wild has just gone live in Japan and it contains the usual mixture of sweeping scenery, epic set-pieces and action-packed gameplay.

It also features a pretty juicy reveal which hasn't been seen in any other footage so far, so here's another spoiler warning.

What are your theories on this mythical beast? Could it be a major character in the story, or a boss battle? A descendent of Volgavia? Let us know your predictions by posting a comment.
