Marshtomp has the ability Torrent. With this ability, the power of Marshtomp's Water-Type attacks increases by 50% once its HP falls below one-third of its maximum. Marshtomp from the Dream World can have a second ability, called Damp. With this ability, no Pokémon will be able to use Selfdestruct and Explosion while the Pokémon with the Damp Ability is on the field because Damp nullifies these moves.
Marshtomp takes the appearance of a blue mudfish with four legs. Its cheeks and stomach are orange, and the fins on its head and tail are grey in color.
