Strong point: Defense — higher than 98% of species. Its weakest point is Sp. Def — lower than 71% of species. It does not evolve: it does not come from anything and does not change into anything. On defense it has 3 weaknesses, 10 resistances and 1 full immunity. Poison-type moves do nothing to it at all.
Base stats
Last column: what percentage of 1084 species and regional forms have a lower value. Strong point: Defense.
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 (85) is 25 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.

How players use it
Data from 44,274 ranked battles on Smogon (Gen 9 UU, 2026-07). These are not numbers from the game — they are player habits. Gen 9 UU is one tier lower: it is played without the Pokémon most often used in OU, so the same species hold completely different places here.
Rank 176 among 274 Pokémon in use — it is on 0.1% of teams.
Each row is a separate distribution, not a single set: the most common item and the most common move do not have to appear on the same Pokémon.
Pokédex entry
When attacked, this Pokémon will wield the tendrils on its body like fists and pelt the opponent with a storm of punches.

Variant gallery
The gallery shows only the appearance variants that exist for this Pokémon. Every image shows the same character and differs in source — a Pokémon HOME render or a pixel sprite — and in coloring, regular or shiny.
Breeding
All Egg Groups →Offspring can come from 275 species from the same Egg Groups (with opposite genders) or from Ditto. Below are the first 12 by Pokédex number.
The Egg hatches after 35 cycles, which is roughly 9,200 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.
