What it does on the ladder
Chesnaught appears on 0.02% of Regulation M-B teams, which
is 253rd of the 277 Pokémon with enough games to measure.
The move it almost always carries is Body Press, on 91.9% of sets.
The item is usually Leftovers at 91.3%.
The ability is split: Bulletproof on 96.2% and Overgrow on 3.8%.
Those are Smogon's published usage figures, not anything measured here, and they describe what
the ladder plays rather than what is strongest. The full set is in the panel above.
The Pokémon itself
Chesnaught is number 652 in the National Dex, a Kalos Pokémon, Grass and Fighting
with a base stat total of 530 — 48th of the 234 Pokémon
legal in this regulation. Its best stat is Defense at 122, 23rd
in the format; its weakest is Speed at 64, 163rd.
It can have Overgrow and Bulletproof.
The Champions module tiers it UU.
It sits in a 3-stage line: Chespin → Quilladin → Chesnaught.
Not all of that line is legal in this regulation — Chespin and Quilladin are not.
What gets through
As Grass and Fighting, 6 of the eighteen attacking types do extra damage to it, and Flying lands for quadruple. It
resists 6. The board above
has all of it. One other legal Pokémon shares the same typing and the same board: Decidueye-Hisui.
What threatens it
Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is
computed, not measured: the most-played Regulation M-B Pokémon carrying a damaging
move of a type Chesnaught takes extra damage from.
- Incineroar — Flare Blitz (Fire, ×2), on 91.1% of its sets
- Sneasler — Dire Claw (Poison, ×2), on 73.9% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.9% of its sets
- Whimsicott — Moonblast (Fairy, ×2), on 96.7% of its sets
- Farigiraf — Psychic (Psychic, ×2), on 72.4% of its sets
- Floette-Mega — Dazzling Gleam (Fairy, ×2), on 97.8% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Chesnaught reaches
127 Speed; left uninvested with a neutral nature it sits at
84. Invested, it outruns 4 of the 20
most-used Pokémon in the regulation when they are invested too — which is the comparison that
decides who moves first.
It weighs 90 kg, so Grass Knot and Low Kick hit it for 80 base
power. That is a real consideration in a format where both are common.
Its move pool
Chesnaught learns 119 moves in the Champions data.
71 of them do damage, across 14 of the eighteen
types, and 25 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Focus Punch at 150 base power.
It also has priority: Feint at +2.
That pool is what the team builder reads from when you seat it, and the
damage calculator will take it as the attacker with
the form already chosen.
