How to Evolve Grubbin in Pokémon Sun and Moon

Last Updated: January 26, 2022

Want to learn exactly how to evolve Grubbin through all of its forms in Pokémon Sun and Moon? Once you reach level 20, Grubbin can evolve into Charjabug, which later evolves into the Bug/Electric-type Vikavolt. We'll walk you through Grubbin's evolution all the way through Vikavolt!

Steps

1
Get a Grubbin. You have a 10% chance of finding Grubbin on Route 1, Route 4, Route 5, and Route 6, so finding one may take a while. You'll find one at anywhere from level 3 to level 17, depending on the route in which you are searching.^{[1]

- Net Balls are a good ball to catch Grubbin with since they work best on Bug and Water-type Pokémon. If you're at the beginning of the game, all Poké Balls have a 100% catch rate on Route 1 (note that this won't be the case later on in the game).
2
Level up your Grubbin to level 20. Since Grubbin is a Bug-type Pokémon, it is super effective against Grass, Dark, and Psychic-type Pokémon.
- If Grubbin keeps fainting in battle, turn on Exp. Share, which you can find in your bag.^{[2]

Go to Vast Poni Canyon on Poni Island. This is the last island you'll encounter in the game. You'll need to be inside the canyon to evolve your Charjabug.^{[4]

Level up your Charjabug inside Vast Poni Canyon to evolve into Vikavolt. This works at any level except for level 100, so you can have a Vikavolt as low as level 21.
- You'll find Fighting-type Pokémon like Machoke, Dark/Flying-type Pokémon like Murkrow, Steel/Flying-type Pokémon like Skarmory, Rock-type Pokémon like Boldore and Lycanroc, Rock/Fairy-type Pokémon like Carbink, and Dragon-type Pokémon like Jangmo-o in the canyon. Battle these to gain experience and level.
- You can also give your Charjabug a Rare Candy to gain a level.^{[5]

Top Answerer

Cosmog evolves into Cosmoem at level 43, and then either Solgaleo or Lunala (Solgaleo if you have Pokemon Sun, and Lunala if you have Pokemon Moon) at level 53.

Try turning the experience share on and battling with your other Pokemon, or switching Grubbin out immediately when you go into battle.
Question

In Sun, I completed the whole Ultra Beast quest and I tried to get Necrozma. When I went to its spawn, no matter how long I tried, it would not spawn. Did I do something wrong?

Use a max repel, make sure the Pokemon in the first slot in your team is under level 75, and run around in the grass in Ten Carat Hills' farthest hollow until Necrozma shows up.
