Is Weezing Good in Let's Go Pikachu & Eevee Playthrough?
Only in Let's Go Eevee. Weezing has decent bulk, but Poison coverage struggles to find relevance against the gym and E4 lineup. A defensive option that doesn't hit hard enough to earn the slot.

How to Get Shiny Weezing in Let's Go Pikachu & Eevee
In Let's Go Pikachu & Eevee, the strongest route to a Shiny Weezing is Catch Combo, which reaches about 1 in 274 at full boosts. Pick a method and tune your setup below to see live odds. Compare Shiny Weezing odds across every game
Let's Go Pikachu & Eevee Shiny Weezing Calculator
2 MethodsThe best route is Catch Combo at full boosts, about 1 in 274 on each try. Tune it below.
Catch Combo: Catch one species back-to-back. A Lure stacks on top of a 31-plus combo.
Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.
How many you have done, or plan to do.
| Chance | Encounters |
|---|---|
| 10%lucky few | 29 |
| 25%one in four | 79 |
| 50%coin flip | 190 |
| 90%very likely | 630 |
How is this calculated?
Every encounter has the same shiny chance, the Shiny Odds Per Try shown above. Each one is a separate roll that does not care how many you have already done, so the more you hunt, the higher your overall chance of at least one shiny. The formula below turns your odds and your number of tries into that combined chance.
chance after N tries = 1 − (1 − p)^N, where p = 1 / odds per try
Example at 1 in 8,192 (classic full odds): about 864 encounters for a 10 percent chance, 5,678 for 50 percent, and 18,862 for 90 percent.
The table above flips that around: it shows how many encounters it takes to reach a 10, 25, 50, and 90 percent chance at your current odds. Turning on boosts like the Shiny Charm, sandwiches, or chains improves your odds, so the encounter numbers drop.
These are estimates, not promises. Most games have no pity counter, meaning no guaranteed shiny no matter how many you hunt, so even Very Likely is not guaranteed: some hunters find one early, others go well past that point.
For time estimates and charm math, open the Let's Go Pikachu & Eevee shiny odds calculator with Weezing already selected.
Weezing Weakness
Type-wise, Weezing takes extra damage from Ground and Psychic. The Poison typing picks up 5 resistances to work with. Weezing's physical bulk (base 120 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Ground, Psychic |
| 0.5x (Resist) | Grass, Fighting, Poison, Bug, Fairy |
Weezing Evolutions
Weezing is what Koffing becomes, and it doesn't evolve any further. The evolution from Koffing pushed Weezing to 490 total stats. HP saw the largest single gain at +25. View every chain in the Evolution Chart.
How to Evolve
Let's Go Weezing Best Moveset
120 Defense at 90 Attack behind Poison typing. AbilityLevitate in standard play negated Ground weakness entirely, the one type that should hit Poison super-effectively. Without it, the moveset is vulnerable to Ground, the most common offensive type in the format. Physical Poison TermStab hits from real bulk, but the lost immunity changes everything.
Best Build

Relaxed raises Defense and lowers Speed. Madam Celadon sets this nature when you pick Yellow, then Pink. It costs 10,000 Pokedollars and lasts for the rest of the day.
Candy for Weezing
Koffing Candy
Tough Candy
Tough Candy L
Tough Candy XL
Koffing Candy raises every stat, but only Koffing and Weezing can eat it. The stat candy that goes with Weezing is Tough Candy (Defense), and any Pokemon can eat it; Tough Candy L needs level 30 and Tough Candy XL needs level 60 or higher.
Master Trainer
Donnie battles with one level 75 Weezing that knows Flamethrower, Thunderbolt and Taunt. It takes extra damage from Ground and Psychic moves. Win to earn the Weezing Master title. Find Donnie in Rocket Hideout.
Moves List
The level-up pool tells the story here. Weezing learns Self-Destruct and Sludge Bomb naturally, plus enough variety that TMs feel like bonuses. Psychic and Normal coverage and more extends the reach beyond that.
