Grubbin is one of the first new Pokémon that we were introduced to for the upcoming Pokémon Sun/Moon Nintendo 3DS game. Grubbin is a Bug Type Pokémon that evolves into Charjabug, a Bug and Electric type Pokémon. The final evolution of this trio is Vikavolt, also a Bug and Electric type Pokémon. This trio seems to match up with the Caterpie, Metapod and Butterfree evolution chain. This trio of bug type evolutions at the beginning of the game seems to be a trend in Pokémon games and I am happy that the game is still keep some aspects the same. My prediction is that Grubbin will evolve at Level 7 and Charjabug will evolve at Level 10 into Vikavolt!
CHARJABUG (Level 7)
VIKAVOLT (Level 10)
