Sham
The Guardian of Ruin and Birth
I wished the Sun and Moon anime emphasized more on how rare Z-Crystals were than they did. I realize some Z Crystals are available via finding them on the ground but I felt like the scarceness of them were taken away once adapted into the anime. I think the most jarring part was when Hapu pulled out an entire box of them and just let Ash/Pika choose.
