Weezing's stats are solid on their own, but Levitate is what pushes it over the line. It gives it a Ground immunity. Only weak to Ground and Psychic. Flexible enough to run physical or special sets. A longtime staple going back to Gen 1.

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

If one of the twin KOFFING inflates, the other one deflates. It constantly mixes its poisonous gases.

Weezing Weakness

Avg

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

Weezing is what Koffing becomes. Breed it for Koffing eggs (average hatch time). A decent partner pool for breeding via one egg group. Eggs are average hatch time. The evolution from Koffing pushed Weezing to 490 total stats. HP saw the largest single gain at +25.

Fire and Electric coverage keeps opponents guessing about Weezing's real targets. Black Sludge provides Poison-type passive recovery while max HP and Defense EVs and Bold nature handle the stat profile. Levitate ties it together.

Breeding's the move. Curse and Destiny Bond give Weezing options it can't learn any other way, and coverage across 8 types already covers a decent range on top of Sludge Bomb and Sludge. The egg moves push it further.

You're catching Koffing first, not Weezing. Koffing appears at solid rates in the encounters below. The step cards map the full 2-stage line with evolution methods between each stage.

How to Obtain Weezing in HeartGold & SoulSilver

To get Weezing, start by catching Koffing through walking and fixed encounters at Lv. 14-21. The chain covers 1 catchable stage before reaching the final form.

    Step 2Weezing
  • Weezing looks average on paper at 490 BST. But Levitate is why it sees play — build around that and it pulls its weight. B-Tier on our tier list.

  • 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 gets Levitate, Neutralizing Gas, and Stench. But Levitate is the one that matters — it's the centerpiece of every viable set. Build around that.

  • Weezing is leaning toward the physical side (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.
