Pokémon Jupiter (Japanese: ポケットモンスター木星 Pocket Monsters Jupiter) and Pokémon Saturn (Japanese: ポケットモンスターズサターン Pocket Monsters Saturn) are the second paired versions of Generation VII and are the sequels of Pokémon Sun and Moon, as well as serving as continuations/sequels to Pokémon Red, Green, Blue and Yellow, respectively. They are set in the new Fija region, a neighboring region of Alola. The Fija region was inspired by the real life "island country" Fiji.
They were revealed by Tatsumi Kimishima via Pokémon Direct (Nintendo Direct) on July 25, 2017.
The Fija Guardian Pokémon Mapo Ko'na rules over Jupiter and Saturn, whom lends its power to Solgaleo and Lunala in order for them to achieve their Eclipse forms, which align with Jupiter and Saturn.
Solgaleo's Eclipse form is the mascot of Pokémon Jupiter, while Lunala's Eclipse form is featured in Pokémon Saturn. Their types change, becoming Fire/Steel and Dark/Ghost, both losing the Psychic-type, respectively. They receive Z-Crystals with their new forms (Ecliolgalium Z and Ecliunalium Z) and Z-Moves (which they can only use if they are in their Eclipse forms with the move Eternal Eclipse); Infuriating Jupiter Inferno for Solgaleo and Overshadowing Saturn Spectre for Lunala.
Bulbasaur, Charmander and Squirtle return as starters for the Fija region with their new Fijan forms. Bulbasaur becomes Poison/Fairy, Charmander is now a Ghost-type (Ghost/Dragon upon evolution), and Squirtle is a Rock-type (Rock/Steel when evolved). You can receive their original forms (with their Hidden Abilities) from Professor Kukui in the postgame. Each of their final evolutions receive their own Z-Crystals (Fijavenusium Z, Fijacharizium Z and Fijablastium Z) and Z-Moves; Malignant Poison Purge for Fijan Venusaur, Spiritual Dragonbound for Fijan Charizard, and Prehistoric Powerblast for Fijan Blastoise.
The Fija region is heavily inspired by Fiji and its culture. Fiji isn't very far from Hawaii (which Alola is based on). As Fija is next to the Alola region, you can go to Alola in the postgame.
Regional Variants return in Pokémon Jupiter and Saturn, with the Kanto starters' Fijan forms being an example to this. Many Pokémon will receive new Fijan forms, such as Butterfree for example, who becomes Bug/Ghost.
Gyms and Gym Leaders
There are only five Gyms in the Fija region, and each of them give out Stamps instead of Badges.

The Champion is instead titled "Challenger" and is actually unveiled to be the Guardian of the entire Fija region—Mapo Ko'na, a Ghost/Flying Pokémon. It uses five Pokémon (as it is controlling them by telling them what moves to use, etc) before battling against the player by itself as the sixth Pokémon. Mapo Ko'na had chosen Emory, Audrey, Sloan and Lelea to be the Elite Four (in a ceremony) to test Trainers who may be "worthy". If the player happens to defeat Mapo Ko'na, it will bless them and name them as the "Warrior" of the Fija region.

Pokémon Jupiter and Saturn features 25 new Pokémon in the Fija region.
The Baqan Clan are the region's villainous team, who happen to be a newly-resurrected tribe of possessed civilians who want to summon Solgaleo/Lunala and access their Eclipse forms in order to "create new planets". The T.X. Company also serve as the secondary villains, whom are a company who sell "delicious goods"; however, the "goods" have poison and hypnotizing candy inside of them, designed to control the customer.
