Weezing doesn't stand out in any single area, but it gets the job done for in-game teams. Only weak to Ground and Psychic. Been around since Gen 1. Flexible enough to run physical or special sets. It relies on good prediction to keep up.

Nothing fancy in Weezing's spread. It leans mixed with Defense out front. And you'll get 2 Defense stat exp per KO for it. Follows a medium-fast 1M XP curve.

When it inhales poisonous gases from garbage, its body expands, and its insides smell much worse.

Weezing Weakness

Avg

Type-wise, Weezing takes extra damage from Ground and Psychic. The Poison typing picks up 4 resistances to work with. Weezing's physical bulk (base 120 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Breeding's the move. Destiny Bond and Pain Split give Weezing options it can't learn any other way, and Normal and Fire coverage and more already covers a decent range on top of Sludge Bomb and Sludge. The egg moves push it further.

    CHALLENGING
    or evolve from Koffing (Step 1)

  • Weezing brings 490 BST to the table. C-Tier on our list — a situational pick that fills a niche. That 120 base Defense does the heavy lifting.

  • Weezing's biggest threats include Golem (Ground) and Starmie (Psychic), all carrying super-effective STAB moves. Only 2 weaknesses means fewer dedicated counters to worry about.

  • Koffing evolves into Weezing at level 35. Weezing is the final evolution in a 3-stage line starting from Koffing. At 490 BST, it's got solid stats to work with.

  • Weezing is a physical attacker with base 90 Attack. Enough bulk to take a hit or two, too. But the speed tells the real story — at base 60 Speed, it won't be moving first often.

  • Weezing appears in 20 games, including Yellow, Red & Blue, and Gold & Silver.

Available since Red & Blue, Weezing appears in 20 games spanning 9 generations. Beyond its original form, it gained a Galarian form in Generation 8.
