Is Bastiodon Good in Ultra Sun & Ultra Moon Playthrough?

Rock/Steel with among the highest defenses in the game. Resists 10 types but deals almost no damage. Quad weak to Fighting and Ground, which Molayne's E4 and Hapu both exploit. More of a wall than a team member.

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. 8 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.

Pokedex Entry

The bones of its face are huge and hard, so they were mistaken for its spine until after this Pokémon was successfully restored.

This Pokémon is from roughly 100 million years ago. Its terrifyingly tough face is harder than steel.

Bastiodon Ultra Sun & Ultra Moon Guide

  • In Ultra Sun & Ultra Moon, Bastiodon has a 495 base stat total and ranks as C-Tier: a niche pick in Ultra Sun & Ultra Moon's meta. It works best as a support. Stealth Rock with Magoberry is the standard set.

  • In Ultra Sun & Ultra Moon, 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 Ultra Sun & Ultra Moon, 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 Ultra Sun & Ultra Moon, run Stealth Rock, Toxic, Metalburst, and Roar on Bastiodon. Stealth Rock is the most common pick at 0% usage. This set covers the support role with a mix of damage and utility.

Game Availability

Bastiodon first appeared in Diamond & Pearl and has been available in 12 games across 7 generations. Obtainable through wild encounters in most titles where it appears.
