Charjabug or Vikavolt: Which Grubbin evolution to use in which format of Pokemon GO Battle League?

Charjabug is the preferred choice for the Pokemon GO Battle League's Great League and ranks #37 in the Switch category and #68 in the overall category, according to PvPoke. It can take down popular meta picks such as Umbreon, Azumarill, Registeel, Lanturn, and even Medicham in a one-on-one bout with both shields in play on either side of the field.

Charjabug has a humble base Attack stat of 145 compared to Vikavolt's 254. This means in limited CP formats like the Great League, it can have higher Defense and Stamina than Vikavolt, whose CP is inflated due to its much higher Attack stat. For more information on the process of CP calculation, check out our article on it.

Vikavolt is the better option for the Ultra or Master League. That said, it is not a good choice for either. Even with Volt Switch, the creature is not able to make a mark in the higher-leveled formats of GO Battle League. This makes Grubbin's final evolution a lackluster choice for Pokemon GO PvP.

Best PvP moveset for Charjabug and Vikavolt in Pokemon GO

Both Charjabug and Vikavolt have the same preferred attacks, which consist of the following:

• Fast Attack: Volt Switch
• Charged Attack: Discharge and X-Scissor

Volt Switch is the best Fast Attack for Grubbin's evolved forms. It deals 3.6 damage per turn and generates four energy. With this move in play, Charjabug and Vikavolt reach both X-Scissor and Discharge in three turns.

X-Scissor is a Bug-type attack that deals 78 damage (STAB included) and costs 40 energy, while Discharge is Electric-type and deals 78 damage (STAB included) and costs 45 energy.

To conclude, Charjabug is a decent choice for the Great League if you are looking for some spicy picks in the format. Vikavolt may work out as a good attacker in Gyms or Raids in Pokemon GO, but it is not very good in trainer battles.

You should still play the Community Day event, as it gives you many fantastic bonuses and an easy chance to add the Shiny Grubbin family to your collection.
