Shield

Shellder Weakness

Good

Type-wise, Shellder takes extra damage from Electric and Grass. It resists 4 types, giving it decent defensive coverage. Shellder's physical bulk (base 100 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Best Build

No build content available for this Pokemon in Gen 8.

Try selecting a different game/generation filter, or check back later.

The egg pool carries weight here. Aqua Ring and Bubble Beam aren't available any other way for Shellder, and they meaningfully change what it threatens. Stack those on top of Hydro Pump and Surf for solid options.

  • Shellder isn't fully evolved, so it's not built for competitive play. You'll want to evolve it into Cloyster to unlock its full potential. At 305 BST, it's a stepping stone rather than a team anchor.

  • Shellder's biggest threats include Jolteon (Electric) and Exeggutor (Grass), all carrying super-effective STAB moves. Only 2 weaknesses means fewer dedicated counters to worry about. At base 40 Speed, Shellder won't outrun any of these threats so switching to a resist is usually the safer play.

  • Shellder evolves into Cloyster using a Water Stone. Shellder is the base form of this evolutionary line.

  • Shell Armor is the go-to ability for Shellder. It protects against critical hits. Its hidden ability Overcoat can work in specific setups. Skill Link is the other option — pick based on what your team needs.

  • Shellder fills the balanced role. It's a physical attacker with base 65 Attack. Base 40 Speed is low. Priority moves or Trick Room are the way to go. And it's fragile — can't afford to take many hits.

  • Shellder appears in 20 games, including Yellow, Red & Blue, and Gold & Silver.

Shellder has been part of the series since Red & Blue, appearing in 20 titles across all 9 generations. As a Gen 1 original, it's one of the most consistently available Pokemon in the franchise.
