Stats & Training
Tentacool's spread isn't flashy. Sp. Def leads, Defense trails, 1 stats clear the bar. Common in the wild and worth 1 Sp. Def EV, on a slow 1.25M XP grind.
When the tide goes out, dehydrated TENTACOOL remains can be found washed up on the shore.
It drifts aimlessly in waves. Very difficult to see in water, it may not be noticed until it stings.
Tentacool Weakness
Tentacool is weak to Electric, Ground, and Psychic. 7 resistances give it solid defensive coverage on top of that. Tentacool's special bulk (base 100 Sp.Def) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.
| Damage | Types |
|---|---|
| 2x (Weak) | Electric, Ground, Psychic |
| 0.5x (Resist) | Fire, Water, Ice, Fighting, Poison, Bug, Steel |
- Fairy type does not exist — Dragon has fewer checks
- Physical / Special split now per-move (introduced Gen IV)
