Cascoon sits in the middle of its evolution line — stronger than Wurmple but not yet at full power. Most trainers push through to Dustox as fast as possible. Only weak to Fire, Flying, and Rock. Known as the Cocoon Pokemon.

Defense and HP carry most of Cascoon's stat budget. Speed's the obvious dump stat. Common in the wild and yields 2 Defense EVs. Follows a medium-fast 1M XP curve.

CASCOON makes its protective cocoon by wrapping its body entirely with a fine silk from its mouth. Once the silk goes around its body, it hardens. This POKéMON prepares for its evolution inside the cocoon.

Ruby

If it is attacked, CASCOON remains motionless however badly it may be hurt. It does so because if it were to move, its body would be weak upon evolution. This POKéMON will also not forget the pain it endured.

Cascoon Weakness

Avg

Cascoon is weak to Fire, Flying, and Rock-type moves. Cascoon's physical bulk (base 55 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Not a lot to pick from. Cascoon gets Bug STAB for same-type damage, and Poison and Normal coverage rounds things out. You're building around what's available rather than choosing from a deep bench.

    or evolve from Wurmple (Step 1)

  • Cascoon is meant to evolve into Beautifly. At 205 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.

  • Cascoon's biggest threats include Arcanine (Fire), Salamence (Flying), and Golem (Rock), all carrying super-effective STAB moves. At base 15 Speed, Cascoon won't outrun any of these threats so switching to a resist is usually the safer play.

  • Wurmple evolves into Cascoon at level 7. Cascoon evolves into Dustox at level 10. Cascoon is a middle-stage evolution in the Wurmple line.

  • Shed Skin is the go-to ability for Cascoon. It has a 33% chance of curing any major status ailment after each turn. It's Cascoon's only ability.

  • Base 15 Speed is low. Priority moves or Trick Room are the way to go. On offense, Cascoon is leaning toward the physical side (base 35 Attack). Defensively? Fragile — can't afford to take many hits.

  • Cascoon appears in 14 games, including Ruby & Sapphire, FireRed & LeafGreen, and Emerald.

Available in 14 titles since its debut in Ruby & Sapphire, Cascoon spans 7 generations of Pokemon games. It's accessible through catching or hatching as a base form in a solid number of games.
