While most trainers evolve Piloswine into Mamoswine immediately, the unevolved form can still contribute in the right matchup. Electric moves can't touch it, which offsets the 5 weaknesses somewhat. A longtime staple going back to Gen 2. Relies on priority moves or Scarf to keep up.
Nothing fancy in Piloswine's spread. It leans physical with HP out front. And you'll get 2 HP and Attack EVs per KO for it. Follows a slow 1.25M XP grind.
Because the long hair all over its body obscures its sight, it just keeps charging repeatedly.
If it charges at an enemy, the hairs on its back stand up straight. It is very sensitive to sound.
Piloswine Weakness
FragileFire, Water, Grass, Fighting, and Steel-type moves hit Piloswine for super-effective damage. The upside? Electric-type moves can't touch it at all. Thick Fat reduces Fire/Ice damage, further improving the defensive spread.
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)

Step 2Piloswine ✓
At 450 BST, Piloswine is firmly in pre-evolution territory. Evolve it into Mamoswine before bringing it to any serious fight.
Piloswine gets Thick Fat, Oblivious, and Snow Cloak. But Thick Fat is the one that matters — it's the centerpiece of every viable set. Build around that.
Piloswine is a physical attacker with base 100 Attack. Enough bulk to take a hit or two, too. But the speed tells the real story — base 50 Speed is low. Priority moves or Trick Room are the way to go. Fits the attacker role.
Piloswine appears in 18 games, including Gold & Silver, Crystal, and Ruby & Sapphire.
Debuting in Gold & Silver, Piloswine appears in 18 games across 8 generations. A reliable presence in most mainline games, typically found through catching or hatching as a base form.
