Mudkip
The Mud Fish Pokémon
Type: Water
Official Registration #: 258
Entry: One of three pokémon traditionally offered to new trainers at the beginning of their journeys in Hoenn. A small, amphibious pokémon native to Hoennian rivers. It uses its large head fin to sense the flow of water and its large back fin to propel itself through turbulent currents with surprising power for its size. Likewise, the large gills on its cheek allow it to breathe even in the murkiest, muddiest depths, and its physical strength alone allows it to pick up and push boulders along river bottoms. In general, mudkip is a fascinating pokémon, and this is because the species itself carries a number of interesting qualities, not because someone “herd u liek it.”

Marshtomp
The Mud Fish Pokémon
Type: Water/Ground
Official Registration #: 259
Entry: The evolved form of mudkip, by battle experience. An amphibious pokémon primarily native to rivers and banks, marshtomp had to develop strong, bulky legs to compensate for the fact that its habitat lacks stable footing. Thus, marshtomp is capable of literally standing through even the fiercest earthquakes, the likes of which routinely plague its volcanic home region of Hoenn. A less composed young researcher would likely say that marshtomp has had the foresight to “not skip leg day,” but luckily, the writer is not the storage system administrator of Sinnoh.

Swampert
The Mud Fish Pokémon
Type: Water/Ground
Official Registration #: 260
Entry: The evolved form of marshtomp, by battle experience. Never let its seemingly cute species name fool you. In actuality, swampert is a four-foot-tall mass of pure, sea-tempered muscle. It is powerful enough to tow ships to shore, rend boulders in two with one swipe of its bulky arms, swim against the current of stormy waves, dive to the depths of the Hoennian sea, and spew jets of water that can tear holes in the hull of the ships it had towed to shore at the beginning of this list. About the only thing cute about it is the fact that it still wears a perpetual grin and enjoys belly rubs and literally sucking down insect prey, just like its ancestral cousin, quagsire.

Mega Swampert
The Mud Fish Pokémon
Type: Water/Ground
Official Registration #: 260+
Entry: The advanced form of swampert, via swampertite. Mega swampert is the only starter that doesn’t change drastically in terms of physiology or elemental affinity upon mega evolution. It simply becomes more muscular and adept at punching things … which is why it’s perhaps a bad idea to imply its mega evolution isn’t as interesting as its peers’ while it’s within earshot.
