Pokémon has announced the evolutions of the starter Pokémon in 'Sun' and 'Moon'.

The special demo for 'Pokémon: Sun' and 'Pokémon: Moon' will hit the Nintendo eShop on October 18, and the developers have now released details of the evolutions for each of the three starter Pokémon.

Rowlett will evolve into grass and flying type Dartrix, Litten evolves into fire type Torracat, and Popplio will evolve into Brionne, a water type.

The description of the evolutions on the official Pokémon website says: "Dartrix cares a great deal about its appearance, grooming its feathers in every spare moment. At times, this Pokémon feels so bothered by its dirty or ruffled feathers that it can't focus on battle. It's up to each Trainer to help Dartrix overcome this troublesome stage. If this Pokémon is with a Trainer who helps it through, its strength will grow hugely!

"Torracat has a great love for battle and will attack so relentlessly that its opponents lose the will to fight. And yet it sometimes behaves like spoiled child in front of Trainers or Pokémon with whom it has built a relationship of trust.

"Brionne always acts cheery and positive. Even when it's feeling sad, this Pokémon doesn't allow its sorrow to show. It's said that Brionne will only reveal a sad expression to a Pokémon or Trainer to whom it has opened its heart completely."

Alongside the evolution news, Pokémon developers have also released details of the game's new features.

'Pokémon: Sun' and 'Pokémon: Moon' allows players to see other people playing near them and connect to them via the new Festival Plaza. Interacting with other players in this area earns coins that can be used in exchange for rewards.

The newly added 'Poke Pelago' offers an area of islands specifically for Pokémon stored in a player's PC box. Pokémon here can explore a variety of islands, with the chance of bringing back interesting items.

Pokémon developers also answered a question that fans have been asking since the announcement of the new games, by confirming that Mega Evolution will indeed feature in 'Sun' and 'Moon'. All the Pokémon that were able to Mega Evolve in the last games will also be able to Mega Evolve in the new set.

'Pokémon: Sun' and 'Pokémon: Moon' will be available for demo on October 18, with the full game released on November 18.
