Gastrodon#423

Its greatest asset is HP — higher than 95% of species. Weak point: Speed — lower than 83% of species. This is the final form of its line — it does not evolve any further. Defensively it can rely on 1 weakness, 4 resistances and 1 full immunity. Watch out for the Grass type — damage from it is quadrupled.

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

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

Which nature to choose

Attack (83) and Sp. Atk (92) are nearly equal, so neither of these two stats can be lowered for free. The price has to be paid in defense — in the weaker one, because Defense does not stop anything here anyway.

  • Quiet +SpA · −Spe Slow and attacking on both sides — the cheapest thing to give up is what it does not have. Under Trick Room this drop actually helps.

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

TCG cards (6)

All Gastrodon cards →

Gastrodon has 6 cards in 4 sets. The oldest of them are shown below.

Offspring can come from 165 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.
