Sun and Moon's Alola Pokedex replaces gyms with Island Trials and Totem Pokemon. Z-Moves give every Pokemon one big nuke per battle. Alolan forms turn Gen 1 classics like Ninetales (now Ice/Fairy) into new typings entirely. No Mega Stones until postgame. Use the type filter to browse Alolan forms and new Gen 7 species side by side.

802 total. The Alola Pokedex is split into four island-specific dexes covering around 300 Pokemon available during the story. The rest require trading or transferring from other games via Pokemon Bank.
Z-Moves are powered-up attacks you can use once per battle. A Pokemon needs to hold a Z-Crystal matching its type (or a species-specific crystal). Offensive Z-Moves deal massive damage, and support Z-Moves boost stats or apply unique effects. Every type has a Z-Crystal, so any Pokemon can use one.
Alolan forms are regional variants of Gen 1 Pokemon that adapted to the Alola region. Alolan Ninetales is Ice/Fairy instead of Fire. Alolan Marowak is Fire/Ghost instead of Ground. They have different types, stats, abilities, and movepools. Only Kanto Pokemon got Alolan forms.
Gen 7. Nintendo 3DS, 2016. Sun and Moon ditched the gym formula for Island Trials and Totem Pokemon. Z-Moves and Alolan forms debuted here. The Alola region is based on Hawaii, and the pacing is story-heavy compared to older entries.
Island Trials replace traditional gyms. Each trial is a challenge (finding items, answering questions, battling through an area) ending in a fight against a Totem Pokemon, a buffed wild Pokemon with stat boosts and ally support. After clearing all trials on an island, you battle the island's Kahuna. Four islands, seven trials.
