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 |
- Dark and Steel types added — Fairy does not exist yet

Base Stats
TENTACOOL’s body is largely composed of water. If it is removed from the sea, it dries up like parchment. If this POKéMON happens to become dehydrated, put it back into the sea.
TENTACOOL absorbs sunlight and refracts it using water inside its body to convert it into beam energy. This POKéMON shoots beams from its crystal-like eyes.
