How to Get Lairon in Ruby & Sapphire
One deep cave room is all Lairon claims in the wild, uncommon at levels 40 to 44. Evolving a level-32 Aron is far less of a slog than digging that deep for the higher-level spawns.
Wild Lairon may be holding when caught:

How to Get Shiny Lairon in Ruby & Sapphire
Lairon roams Victory Road as an uncommon wild encounter, so meet enough of them and one may turn up shiny. Compare Shiny Lairon odds across every game
Ruby & Sapphire Shiny Lairon Calculator
2 MethodsBoth methods here share the same odds, about 1 in 8,192 on each try. Pick whichever fits how you play.
Full Odds: Walk through grass, surf, or fish. Every encounter is its own independent shiny roll.
Breeding: Hatch eggs of this line; each egg rolls at the base shiny rate (no Masuda before Gen IV).
How many you have done, or plan to do.
| Chance | Encounters | Time |
|---|---|---|
| 10%lucky few | 864-- | -- |
| 25%one in four | 2,357-- | -- |
| 50%coin flip | 5,678-- | -- |
| 90%very likely | 18,862-- | -- |
Time assumes -- at your pace and does not change your shiny odds.
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.
Curious how fast a hunt could go? Work out your Ruby & Sapphire shiny odds for Lairon.
Lairon Weakness
Fighting, Ground, and Water moves hit Lairon for super-effective damage. Fighting and Ground hits land at 4x, so they're the biggest threat. The upside? Poison-type moves can't touch it at all. It resists 9 types, so it can switch into a lot of moves safely. Lairon's physical bulk (base 140 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 4x (Critical) | Fighting, Ground |
| 2x (Weak) | Water |
| 0.5x (Resist) | Ice, Psychic, Bug, Rock, Ghost, Dragon, Dark |
| 0.25x (Resist) | Normal, Flying |
| 0x (Immune) | Poison |
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move

LAIRON feeds on iron contained in rocks and water. It makes its nest on mountains where iron ore is buried. As a result, the POKéMON often clashes with humans mining the iron ore.
