“Mudsdale is known for its powerful body as well as its emotional fortitude, which keeps it from being agitated by anything. It never cries out, no matter what kind of trouble it’s in, and it defeats its opponents with a single powerful blow. Its legs are coated in protective mud, and the weight of this coating increases the force of its kicks. One kick, and a car is a pile of scrap! Mudsdale’s running speed is not too swift, but it has excellent power and stamina. It can carry on for three days and three nights despite dragging loads of over 10 tons! When Mudsdale gallops in earnest, the power of each hoof-clop can dig out huge holes, even in asphalt. Mudsdale is forbidden to run on some of Alola’s public roads. Mudsdale can have the new Stamina Ability, an Ability that no other Pokémon has had before. With the Stamina Ability, this Pokémon’s Defense goes up by 1 when it’s hit by an attack.”
Mudsdale is a large, equine Pokémon with short, brown fur and a black-and-red mane and tail. It has heavy-lidded, black eyes with a red rim along the bottom, a red blaze on its muzzle, and long, pointed black ears with brown insides. This Pokémon’s mane extends down around its eyes. Along the top of its neck, its mane is black with red at the tip and stands up straight. On either side of its neck, the mane forms three thick structures similar to dreadlocks with red mud around the tips. The mane extends all the way down Mudsdale's back in a thin line before becoming its tail. The tail appears similar to its dreadlocks. The tail is much larger than the dreadlocks on its mane, but still has mud around the tip. However, there are several black notches missing from the mud. Around its hooves is a protective coating of red mud, which has three notches around the bottom.
Mudsdale is known for both its powerful body and emotional fortitude, which prevents it from becoming agitated. Regardless of the trouble it is in, it will never cry out and defeats opponents with a single blow. The mud around its legs gives its kicks extra force; one kick can turn a car into a scrap pile. When galloping, its hooves can dig holes in asphalt. While it is not swift, it has excellent stamina and can continue on for three days and three nights while dragging over 10 tons.
Mudsdale appears as a downloadable fighter in Pokkén Tournament 2, being a new Power fighter. Mudsdale is a close-quarters fighter, whose attacks are generally slower but much more powerful compared to those of other Pokémon.
