Stats & Training
Bastiodon's all-in on Defense at the expense of Speed. The mixed lean is obvious from the bars. Yields 2 Defense EVs and follows a standard growth curve.
Any frontal attack is repulsed. It is a docile Pokémon that feeds on grass and berries.
When attacked, they form a wall with their shieldlike faces to protect their young.
Bastiodon Weakness
Bastiodon's Rock/Steel typing leaves it vulnerable to Fighting, Ground, and Water. Fighting and Ground hits land at 4x, so they're the biggest threat. It shrugs off Poison-type attacks completely. 9 resistances give it solid defensive coverage on top of that. Bastiodon's physical bulk (base 168 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)
In Diamond & Pearl, Infernape can KO Bastiodon with Close Combat (142-167%). Flygon threatens a KO with Earthquake (115-135%). Swampert's Earthquake also KOs at 99-117%.

Bastiodon Guide
In Diamond & Pearl, Bastiodon has a 495 base stat total and ranks as C-Tier: a niche pick in Diamond & Pearl's meta. It works best as a support. Stealth Rock with Leftovers is the standard set.
In Diamond & Pearl, watch for Lucario (Fighting), Garchomp (Ground), and Milotic (Water) when using Bastiodon. They all hit it super-effectively with STAB. Lucario is the most dangerous since Fighting moves deal 4x damage. At base 30 Speed, Bastiodon won't outrun any of these threats so switching to a resist is usually the safer play.
Sturdy prevents being KOed from full HP, leaving 1 HP instead. That's the one you want on Bastiodon. Soundproof is the hidden ability. Niche, but it has its uses.
In Diamond & Pearl, Bastiodon fills the support role. It's a physical attacker with base 52 Attack. Base 30 Speed is low. Priority moves or Trick Room are the way to go. And it's tanky enough to absorb a few hits.
In Diamond & Pearl, run Stealth Rock, Roar, Metalburst, and Protect on Bastiodon. Stealth Rock is the most common pick at 19% usage. This set covers the support role with a mix of damage and utility.
