Shellder is technically a pre-evolution of Cloyster, but it can still hold its own in battle. Only weak to Electric and Grass. Flexible enough to run physical or special sets. Been around since Gen 1.

Shellder's spread isn't flashy. Defense leads, Sp. Def trails, 1 stats clear the bar. Common in the wild and worth 1 Defense stat exp, on a slow 1.25M XP grind.

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

Gen 2 build content has limited support (no abilities).

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

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

  • Shellder fills the balanced role. It's a special attacker with base 45 Sp. Atk. 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.
