>>38707170The anime has always been notorious for foreshadowing, ever since Ho-Oh in episode 1.
Out of all possible Pokemon faces they could have slapped on that box, they chose Axew. Don't know what the point of the Axew face on the box is even supposed to be for (food? Axew being imported to the islands?), but it's a nice means of subtle foreshadowing.
But we won't know til something happens.
