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

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.

Onix Weakness
Onix's Rock/Ground typing leaves it vulnerable to Water, Grass, Ice, Fighting, Ground, and Steel. Water and Grass hits land at 4x, so they're the biggest threat. It shrugs off Electric-type attacks completely. The Rock/Ground typing picks up 5 resistances to work with. Onix's physical bulk (base 160 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 4x (Critical) | Water, Grass |
| 2x (Weak) | Ice, Fighting, Ground, Steel |
| 0.5x (Resist) | Normal, Fire, Flying, Rock |
| 0.25x (Resist) | Poison |
| 0x (Immune) | Electric |

Onix Evolutions
Onix is a single-stage Rock/Ground type. There's nothing to evolve, so its 385 base stats are what you build around. View every chain in the Evolution Chart.
How to Evolve
Let's Go Onix Best Moveset
160 Defense on a Rock/Ground frame with 35 HP and 45 Attack. The physical wall looks massive until the HP reveals how little total damage it actually absorbs. The moveset has no offensive output. No Steelix evolution exists in this format either.
Best Build
Impish raises Defense and lowers Sp. Atk. Madam Celadon sets this nature when you pick Yellow, then Blue. It costs 10,000 Pokedollars and lasts for the rest of the day.

Moves List
The level-up pool tells the story here. Onix learns Earthquake and Iron Tail naturally, plus enough variety that TMs feel like bonuses. Normal and Steel coverage extends the reach beyond that.
