Mid-stage Pokemon like Charjabug rarely see competitive play outside of special formats. It's a waypoint on the road to Vikavolt, which is where the real potential kicks in. Works well under Trick Room. Only weak to Fire and Rock.

Charjabug's built to absorb hits, not race for knockouts. Physical bulk with Defense doing the heavy lifting. And the medium-fast 1M XP curve means it won't take forever to bring up, worth 2 Defense EVs.

Best Build

No build content available for this Pokemon in Gen 7.

Try selecting a different game/generation filter, or check back later.

Don't skip the egg moves. Charjabug picks up Electroweb and Endure only through breeding, and both fill gaps the natural movepool can't. STAB runs through Thunderbolt and Wild Charge while Dark and Ground coverage and more adds range.

    or evolve from Grubbin (Step 1)

  • At 400 BST, Charjabug is firmly in pre-evolution territory. Evolve it into Vikavolt before bringing it to any serious fight.

  • Watch for Blaziken (Fire) and Golem (Rock) when using Charjabug. They all hit it super-effectively with STAB. Only 2 weaknesses means fewer dedicated counters to worry about. At base 36 Speed, Charjabug won't outrun any of these threats so switching to a resist is usually the safer play.

  • Grubbin evolves into Charjabug at level 20. Charjabug evolves into Vikavolt using a Thunder Stone. Charjabug is a middle-stage evolution in the Grubbin line.

  • Battery ally Pokémon's moves have their power increased to 1.3× — that's the one you want on Charjabug. It's the only ability Charjabug has.

  • Charjabug is a physical attacker with base 82 Attack. Enough bulk to take a hit or two, too. But the speed tells the real story — base 36 Speed is low. Priority moves or Trick Room are the way to go. Fits the trick room role.

  • Charjabug can be found in Scarlet & Violet, Sword & Shield, Sun & Moon, and Ultra Sun & Ultra Moon.

Since Sun & Moon, Charjabug has been obtainable in 4 games. A Generation 7 debut means a shorter history, but Charjabug has appeared steadily across every generation since.
