Gulpin

Not many things happened for Gulpin in this generation. It still has a similar movepool and the same counters, but it can hold its own. With great HP, high defenses and access to Stockpile to boost them even higher, Gulpin can be a great wall. Along with great defensive stats, Gulpin gets a useful defensive ability, Liquid Ooze. This makes Pokemon take damage from absorbing moves such as Giga Drain or Leech Seed, which is useful against Pokemon such as Ferroseed. With the ability to run a decent amount of sets, it can fit its way into a variety of teams. Gulpin's Poison-type is very beneficial, as absorbing Toxic Spikes works out well in the long run and helps out teammates such as Wynaut and Thick Fat Munchlax, and gives Gulpin weaknesses to only Ground- and Psychic-type attacks. Thankfully, these are easily covered. All in all, it's a sure thing that this little venomous blob will keep marching on, devouring any foes that dare stand in its way.
