The seventh generation of Pokémon games is dominated by Pokémon Sun and Moon (along with the Alola region), but this era includes more titles than that. In particular, Gen 7 (2016 to 2018) included three games in its lifetime: Sun and Moon, Ultra Sun and Ultra Moon, and, finally, Let's Go, Pikachu, and Eevee. The latter is an updated remake of Pokémon Yellow with a mixed element from the mobile game Pokémon GO.
In Pokémon Sun & Moon, who are the starters?
The Pokémon starters for Gen 7 may not be the most famous among all the characters in the franchise (that honor belongs to Gen 1 starters), but they are well-known in their own right, especially due to their simpler but functional designs.
Rowlet is a Grass/Flying-type Pokémon that looks like a plain owl with a bow tie made of leaves. It then evolves into Dartrix at level 17, and then into Decidueye, the Grass/Ghost-type Pokémon, which launches at level 34. With its awesome Ghost-type and signature arrow shot, Decidueye has the coolest final evolution design of the group as well (never mind that it isn't the most powerful).
Litten is a Fire-type cat Pokémon that has a unique color palette. At level 17, it evolves into Torracat, and finally into the powerful Fire/Dark-type Incineroar starting at level 34.
Popplio is a water-type Pokémon that resembles a happy seal. It evolves first into the water-type Pop Star Pokémon Brionne at level 17, then into the water-type Primarina at level 34. Primarina is probably the best dual type in the list, with little to no resistance and access to Fairy-type moves that are a destructive force of their own.
In Pokémon Let's Go, who are the starters?
Both Pokémon: Let's Go, Pikachu! and Let's Go, Eevee! feature Gen 1 Pokémon as the games take place in the Kanto region. The starters are each of the game's namesakes: Pikachu or Eevee. Both have higher base stats than the regular Pikachu and Eevee that can be seen in the field.
