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

Gyarados is a top-tier pick even without abilities. No Intimidate means it takes more physical damage than in other games, but the offensive power is still outstanding. Water/Flying handles Blaine, Giovanni, and pressures Lance. Mega Gyarados adds Dark typing in postgame for even wider coverage.

In Let's Go Pikachu & Eevee, the strongest route to a Shiny Gyarados is Catch Combo, which reaches about 1 in 274 at full boosts.

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.

Gyarados Weakness

Type-wise, Gyarados takes extra damage from Electric and Rock. Watch out for Electric attacks, those deal 4x damage. Ground moves do nothing thanks to a full immunity. 5 resistances help offset the weaknesses. With 95 HP and balanced defenses, Gyarados can afford to eat a neutral hit or two.

Let's Go Gyarados Best Moveset

Mega Gyarados shifts to Water/Dark at 155 Attack. Let's Go has no abilities, Megas included, so the stat boost and the new typing are the whole upgrade. 155 Attack behind dual TermStab devastates from the moveset. Without Mega, 125 Attack at 81 Speed has no Intimidate to lean on but still hits hard.
