Its greatest asset is Attack — higher than 92% of species. Defensively it can rely on 5 weaknesses and 4 resistances.
Base stats
Last column: what percentage of 1084 species and regional forms have a lower value. Strong point: Attack.
A nature can improve this entry further: its boost hits hardest on Attack, the stat in which this species already leads. Which nature does that — see the list of natures.
Gigantamax does not change any of these numbers — all 34 forms have the same stats, types and abilities as the base form.
Which nature to choose
It hits physically: its Attack (125) is 65 points higher than its Sp. Atk. So the drop hits a stat the set usually does not use at all.
- Jolly +Spe · −SpA Its Speed is higher than 70% of species — ten percent more lifts it past some of the benchmarks that decide who moves first.
- Adamant +Atk · −SpA If you already outspeed what you want to outspeed, those ten percent are better spent on hitting 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.
