How to Get Shiny Mega Aggron in Omega Ruby & Alpha Sapphire

In Omega Ruby & Alpha Sapphire, the strongest route to a Shiny Aggron is DexNav Search, which reaches about 1 in 37 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 Aggron odds across every game

Omega Ruby & Alpha Sapphire Shiny Aggron Calculator
4 MethodsThe best route is DexNav Search at full boosts, about 1 in 37 on each try. Tune it below.
DexNav Search: Sneak up on hidden Pokemon to raise the species Search Level toward 999, then keep a chain going. Every 5th link and the 50 and 100 catch milestones stack extra shiny checks.
Horde Encounter: Every horde throws five Pokemon at you at once, so each battle rolls five shiny chances in one encounter.
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 |
|---|---|
| 10%lucky few | 4 |
| 25%one in four | 11 |
| 50%coin flip | 26 |
| 90%very likely | 85 |
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.

Mega Aggron Weakness
Type-wise, Mega Aggron takes extra damage from Fire, Fighting, and Ground. Poison moves do nothing thanks to a full immunity. 10 resistances give it solid defensive coverage on top of that. Filter reduces SE moves damage, further improving the defensive spread. Mega Aggron's physical bulk (base 230 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 2x (Weak) | Fire, Fighting, Ground |
| 0.5x (Resist) | Normal, Grass, Ice, Flying, Psychic, Bug, Rock, Dragon, Steel, Fairy |
| 0x (Immune) | Poison |
