How to Get Omastar in Diamond & Pearl
Omastar follows from reviving an Omanyte and leveling it to 40. The spiral Pokemon has no wild appearance, so the whole line traces back to a Helix Fossil dug out of the Underground.

How to Get Shiny Omastar in Diamond & Pearl
Omastar evolves from Omanyte, so breed that pre-evo Masuda-style at 1 in 1,638 and raise the spiral shell. Compare Shiny Omastar odds across every game
Diamond & Pearl Shiny Omastar 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.
Soft Reset: Save in front of a static, gift, or legendary encounter, then reset until it sparkles.

| 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 Omastar.
Omastar Weakness
Omastar's Rock/Water typing leaves it vulnerable to Grass, Electric, Fighting, and Ground. Grass hits land at 4x, so they're the biggest threat. 5 resistances help offset the weaknesses. Omastar's physical bulk (base 125 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
| Damage | Types |
|---|---|
| 4x (Critical) | Grass |
| 2x (Weak) | Electric, Fighting, Ground |
| 0.5x (Resist) | Normal, Ice, Poison, Flying |
| 0.25x (Resist) | Fire |
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)

Omastar Diamond & Pearl Guide
Yes. Omastar is a post-game Pokemon. You need to defeat the Elite Four and enter the Hall of Fame first. Omastar becomes available after the main story is complete in Diamond & Pearl.
In Diamond & Pearl, use Omastar as a wallbreaker. Special attacks are the main output. Not the fastest, Surf is the primary attack.
For Diamond & Pearl, run Modest on Omastar. +Sp. Atk is what matters, and the -Attack cut doesn't hurt this set. Fits the wallbreaker role.
Game Availability
One of the original 151, Omastar has appeared in 19 games: most mainline games. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
