Which Generation VII Pokemon evolves into Charjabug?

Grubbin is the Generation VII Pokémon that evolves into Charjabug. It is a Bug-type Pokémon introduced in "Pokémon Sun" and "Pokémon Moon," the main games that launched Generation VII.

Grubbin is listed as National Pokédex number 736, while Charjabug is number 737. In the Generation VII games, Grubbin evolves into Charjabug when it reaches level 20. Charjabug can then evolve into the powerful Bug/Electric-type Pokémon Vikavolt in a special magnetic-field location.

The evolutionary line is built around electricity: Grubbin is a larva-like Pokémon that uses its strong jaws and produces sticky silk, while Charjabug resembles a living battery. The most common mix-up is reversing the direction and saying Charjabug evolves into Grubbin. The correct sequence is Grubbin first, then Charjabug, then Vikavolt. Later games changed some evolution requirements, but they did not change which Pokémon evolves into Charjabug.
