Alola! That's Hello and what the region is called. Welcome to a whole new Pokemon experience taking you from island to island but instead of challenging gyms you challenge the Island trials which are very different from what it used to be. As a reward for completing each island trial you get a z-crystal and 1 step closer to the Pokemon league. What's a z-crystal you might ask? Well, it adds a whole new way of battling with super strong moves you use with your partner. This region you can choose one of 3 starters. The Grass-type Rowlet, The Fire-type Litten and the Water-type Popple.
