Mareanie's stats barely vary. None sit in respectable range with no real gaps. It's a blank slate for EV investment. Worth 1 Defense EV, medium-fast 1M XP curve to max.
This Pokémon wanders the seaside looking for food. It often gets electric shocks from broken Pincurchin spines that it tries to eat.
It has excellent regenerative capabilities. Legs that a Mareanie has lost have a very bitter, astringent flavor—they’re not suitable as food.
Mareanie's Poison/Water typing leaves it vulnerable to Electric, Ground, and Psychic. 8 resistances give it solid defensive coverage on top of that.
| Damage | Types |
|---|---|
| 2x (Weak) | Electric, Ground, Psychic |
| 0.5x (Resist) | Fire, Water, Ice, Fighting, Poison, Bug, Steel, Fairy |
