How to Get Shiny Lairon in Diamond & Pearl
Lairon comes between forms, so chain a shiny Aron at the Fuego Ironworks and let it armor up. Compare Shiny Lairon odds across every game
Diamond & Pearl Shiny Lairon Calculator
2 MethodsThe best route is Masuda Method, about 1 in 1,639 on each try.
Masuda Method: Breed with a parent from a different-language game. Works on any breedable line.
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 | Time |
|---|---|---|
| 10%lucky few | 173-- | -- |
| 25%one in four | 472-- | -- |
| 50%coin flip | 1,136-- | -- |
| 90%very likely | 3,773-- | -- |
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 Diamond & Pearl 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 |
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)

Lairon Diamond & Pearl Guide
In Diamond & Pearl, for a casual playthrough, Lairon works as a placeholder. Steel/Rock coverage is useful early. The real payoff is Aggron. That's where the stats start mattering.
In Diamond & Pearl, use Lairon as a trick room. Physical side carries the damage. It's slow, so Trick Room or priority moves are key.
For Diamond & Pearl, run Adamant on Lairon. +Attack is what matters, and the -Sp. Atk cut doesn't hurt this set. Fits the trick room role.
Game Availability
Debuting in Ruby & Sapphire, Lairon appears in 15 games across 7 generations. A reliable presence in most mainline games, typically found through catching or hatching as a base form.
