Tentacool is technically a pre-evolution of Tentacruel, but it holds its own in formats where Eviolite is allowed. Only weak to Electric, Ground, and Psychic. Known as the Jellyfish Pokemon. Flexible enough to run physical or special sets.
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.
Its eyes are as transparent as crystals. From them, it shoots mysterious beams of light.
Drifts in shallow seas. Anglers who hook them by accident are often punished by their stingers.
Tentacool Weakness
GoodTentacool is weak to Electric, Ground, and Psychic-type moves. 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.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
