As a Poison-type, Swalot fills a straightforward role. Only weak to Ground and Psychic. Known as the Poison Bag Pokémon. Relies on priority moves or Scarf to keep up. Known as the Poison Bag Pokemon.
Swalot's built to absorb hits, not race for knockouts. Balanced defenses with HP doing the heavy lifting. And the standard growth curve means it won't take forever to bring up, worth 2 HP EVs.
It swallows anything whole. It sweats toxic fluids from its follicles to douse foes.

Swalot is what Gulpin becomes. Breed it for Gulpin eggs (average hatch time). A decent partner pool for breeding via one egg group. Eggs are average hatch time. The evolution from Gulpin pushed Swalot to 467 total stats. HP saw the largest single gain at +30.
How to Evolve
Breed with Swalot to get Gulpin eggs easily using 31 partners from the Indeterminate egg group. Notable egg moves include Acid Armor, Curse, Destiny Bond and 3 more.
