Strong point: Attack — higher than 92% of species. This is the final form of its line — it does not evolve any further. On defense it has 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.
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.

How players use it
Data from 574,541 ranked battles on Smogon (Gen 9 OU, 2026-09). These are not numbers from the game — they are player habits.
Rank 20 among 309 Pokémon in use — it is on 9.69% 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

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.
TCG cards (12)
All Rillaboom cards →Rillaboom has 12 cards in 6 sets. The oldest of them are shown below.
Breeding
All Egg Groups →Offspring can come from 351 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.
