Is Gengar Good in Let's Go Pikachu & Eevee Playthrough?

Gengar hits like a freight train with top-tier Special Attack and Speed. Ghost/Poison gives it dominant matchups against Sabrina and Agatha. Ground-type moves are a real threat though, so pick your fights carefully. Mega Gengar in postgame is one of the most devastating options available in Let's Go.

How to Get Shiny Gengar in Let's Go Pikachu & Eevee

In Let's Go Pikachu & Eevee, the strongest route to a Shiny Gengar is Catch Combo, which reaches about 1 in 274 at full boosts. Shininess carries through evolution, so hunting an earlier stage and evolving it counts too. Pick a method and tune your setup below to see live odds. Compare Shiny Gengar odds across every game

Fastest Path

The best route is Catch Combo at full boosts, about 1 in 274 on each try. Tune it below.

Step 1 · Encounter Method2 in Let's Go Pikachu & Eevee

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 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.

Gengar Weakness

Type-wise, Gengar takes extra damage from Ground, Psychic, Ghost, and Dark. Normal and Fighting moves do nothing thanks to a full immunity. 4 resistances help offset the weaknesses. At base 110 Speed, Gengar outspeeds most threats and doesn't need to tank what it can outrun.

Let's Go Gengar Best Moveset

Mega Gengar reaches 170 Sp. Atk, but Let's Go has no abilities, so Shadow Tag never stops opponents from switching. Ghost/Poison TermStab at that power still creates a moveset that forces KOs. Without the Mega, 130/110 in Sp. Atk and Speed is still fast and dangerous, just with less power behind it.

Mild raises Sp. Atk and lowers Defense. Madam Celadon sets this nature when you pick Blue, then Yellow. It costs 10,000 Pokedollars and lasts for the rest of the day.

Candy for Gengar

Gastly Candy raises every stat, but only Gastly, Haunter and Gengar can eat it. The stat candy that goes with Gengar is Smart Candy (Sp. Atk), and any Pokemon can eat it; Smart Candy L needs level 30 and Smart Candy XL needs level 60 or higher.
