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

Weezing Weakness

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.

HeartGold & SoulSilver Weezing Best Moveset

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.

Moves

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.

Weezing Guide

  • In HeartGold & SoulSilver, Weezing looks average on paper at 490 BST. But Levitate is why it sees play. Build around that and it pulls its weight. C-Tier on our tier list. Will O Wisp with Black Sludge is the standard set.

  • In HeartGold & SoulSilver, 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.

  • 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 a special attacker with base 85 Sp. Atk. Enough bulk to take a hit or two, too. Speed tells the real story. At base 60 Speed, it won't be moving first often.

  • For HeartGold & SoulSilver, the core moveset is Will O Wisp, Flamethrower, Painsplit, and Thunderbolt. Will O Wisp leads at 23% usage. This set covers the balanced role with a mix of damage and utility.

Game Availability

Available since Red & Blue, Weezing appears in 20 games spanning 10 generations. Beyond its original form, it gained a Galarian form in Generation 8.
