Last column: what percentage of 1084 species and regional forms have a lower value. Strong point: Defense; weak point: Sp. Def.

A nature can improve this entry further: its boost hits hardest on Defense, the stat in which this species already leads. Which nature does that — see the list of natures.

Which nature to choose

It hits physically: its Attack (95) is 10 points higher than its Sp. Atk. So the drop hits a stat the set usually does not use at all.

  • Adamant +Atk · −SpA The default choice: the boost goes where this species is already strong.
  • Jolly +Spe · −SpA Mid-range Speed means the turn order is still worth fighting for — check exactly whom you will outspeed before you give up power.
  • Hidden Power and Weather Ball still deal damage based on Sp. Atk. If either of them is going into the set, lowering Sp. Atk is no longer free.

A conclusion drawn from base stats alone — a specific moveset can reverse it. All 25 natures.

TCG cards (11)

All Cloyster cards →

Cloyster has 11 cards in 10 sets. The oldest of them are shown below.

Offspring can come from 34 species from the same Egg Groups (with opposite genders) or from Ditto. Below are the first 12 by Pokédex number.

The Egg hatches after 20 cycles, which is roughly 5,400 steps. The exact cycle length depends on the game — newer titles shortened it noticeably — so treat this number as an order of magnitude, not a countdown. Having the Flame Body Ability in your party halves the wait.
