Pokémon Light and Dark Versions

Pokémon Light Version and Pokémon Dark Version are the tertiary paired versions of Generation VI. The games are available on the Nintendo 3DU. The games take place in the new Rabow region.

Both games were revealed during a worldwide announcement by Satoru Iwata through a Nintendo Direct at 3pm GMT on January 1st, 2018. The paired versions were released worldwide (except for certain countries) on December 1st and are available at stores and the eShop. All copies of the game are playable in all seven of the languages that the Pokémon games are released in: Japanese, English, German, Spanish, French, Italian, and Korean.

New Pokémon
There aren't very many new Pokémon in Pokémon Light and Dark, however the new Pokémon are awesome (if you like Eevee)!

The new Pokémon in Pokémon Light and Dark are:

722 Apheon (Bug-type Eeveelution)

723 Aveon (Flying-type Eeveelution)

724 Brawleon (Fighting-type Eeveelution)

725 Draceon (Dragon-type Eeveelution)

726 Eeveeon (Normal-type Eeveelution)

727 Litheon (Rock-type Eeveelution)

728 Obliveon (Ghost-type Eeveelution)

729 Sabreon (Steel-type Eeveelution)

730 Terreon (Ground-type Eeveelution)

731 Venneon (Poison-type Eeveelution)

Rainbow type
The Rainbow type is a new type introduced to balance the Fairy type, which was previously only weak to Poison and Steel. Rainbow type attacks are strong against Fairy types and are resisted by itself and Steel; Rainbow-type Pokémon are weak to Normal-type attacks, resist Fairy- and Rainbow-type attacks and are immune to Bug-type attacks.

Gyms
The gyms are mostly the same as before, but now there are 18 gyms (one per type). The Gym Leaders are: Whitney (Normal), Korrina (Fighting), Falkner (Flying), Janine (Poison), Clay (Ground), Roxanne (Rock), Viola (Bug), Shauntal (Ghost), Jasmine (Steel), Chilli (Fire), Cress (Water), Cilan (Grass), Elesa (Electric), Sabrina (Psychic), Wulfric (Ice), Clair (Dragon), Karen (Dark) and Valerie (Fairy)

Exp. and Levelling
The Exp. mechanics work a bit differently in Pokémon Light and Dark. The max level is Lv. 2000, so you get Exp. faster (the calculations are currently unknown).

Shadow Pokémon
Shadow Pokémon return from Colosseum and XD in a slightly different way. Shadow Pokémon do not appear initially, but after you've beat N, get the Aura Reader from Korrina and the Snag Machine from Jasmine and now, any Johto Pokémon a trainer had (except for Gym Leaders and Elite Four members) are now Shadow Pokémon. Once a trainer's Shadow Pokémon is snagged, it's replaced by an identical version of that Pokémon, minus the Shadow moves. The Shadow moves are: Shadow Rush (typeless, physical, 90 power and deals 25% of the damage dealt to the opponent to you) and Shadow Blast (same as Shadow Rush, except is special instead).
