Marshtomp

Say it: MARSH-tomp

Kids summary (simpler)Tap to expand

Marshtomp is the Mud Fish Pokémon — Water and Ground middle stage between Mudkip and Swampert. In Pokémon GO it is usually candy on the way to Swampert — not a finished raid attacker. Water/Ground hits Fire, Electric, Rock, and Steel well; Grass hits it for 4×. Evolve Mudkip up the line. Hydro Cannon from Mudkip Community Day belongs on Swampert.

Say it: MARSH-tomp

Marshtomp (#259) is a Water / Ground Pokémon in Pokémon GO — the middle evolution of Mudkip. Trainers almost never power Marshtomp for raids; the value is candy and IVs for Swampert (and Mega Swampert). Against Marshtomp, lead with Grass (best).
