Silcoon sits in the middle of its evolution line — stronger than Wurmple but not yet at full power. Most trainers push through to Beautifly as fast as possible. Part of the Gen 3 roster. Only weak to Fire, Flying, and Rock.
Nothing fancy in Silcoon's spread. It leans mixed with Defense out front. And you'll get 2 Defense EVs per KO for it. Follows a medium-fast 1M XP curve.
It prepares for evolution using the energy it stored while it was a WURMPLE. It keeps watch over the surroundings with its two eyes.
Silcoon Weakness
AvgType-wise, Silcoon takes extra damage from Fire, Flying, and Rock. Silcoon's physical bulk (base 55 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move

At 205 BST, Silcoon is firmly in pre-evolution territory. Evolve it into Cascoon before bringing it to any serious fight.
Silcoon's biggest threats include Blaziken (Fire), Dodrio (Flying), and Aerodactyl (Rock), all carrying super-effective STAB moves. At base 15 Speed, Silcoon won't outrun any of these threats so switching to a resist is usually the safer play.
Shed Skin is the go-to ability for Silcoon. It has a 33% chance of curing any major status ailment after each turn. It's Silcoon's only ability.
Silcoon is leaning toward the physical side (base 35 Attack). Fragile — can't afford to take many hits, too. But the speed tells the real story — base 15 Speed is low. Priority moves or Trick Room are the way to go.
