How to Get Forretress in Diamond & Pearl

Since Pineco rarely shows outside honey trees, Forretress takes some patience to build toward. Slather a tree, catch the bag bug, and level it to 31, as the steel form never appears wild.

Catch Pineco at any of these 5 spots to eventually evolve into Forretress.

3 Methods
Fastest Path

The best route is PokeRadar Chain at full boosts, about 1 in 200 on each try. Tune it below.

Step 1 · Encounter Method3 in Diamond & Pearl

PokeRadar Chain: Chain shaking-grass patches without breaking the combo. The rate peaks at a chain of 40.

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.

Step 2 · Boost Your Oddstap to add

ChanceEncountersTime

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.

Where these shiny odds come from: Read our full methodology

For time estimates and charm math, open the Diamond & Pearl shiny odds calculator with Forretress already selected.

Forretress Weakness

Fire moves hit Forretress for super-effective damage. Fire hits land at 4x, so they're the biggest threat. The upside? Poison-type moves can't touch it at all. With 9 resistances, the defensive profile is strong. Forretress's physical bulk (base 140 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokemon Diamond / Pokemon Pearl

Forretress Diamond & Pearl Guide

  • In Diamond & Pearl, use Forretress as a hazard setter. Physical side carries the damage. It's slow, so Trick Room or priority moves are key.

  • For Diamond & Pearl, build your team around Gyarados, Jirachi, and Latias. These have the highest co-usage rates with Forretress in competitive formats. They cover each other's weaknesses.

  • For Diamond & Pearl, run Impish on Forretress. +Defense is what matters, and the -Sp. Atk cut doesn't hurt this set. Fits the hazard setter role.

Game Availability

Available in 16 titles since its debut in Gold & Silver, Forretress spans 8 generations of Pokemon games. It's accessible through wild encounters in most mainline games.
