What it does on the ladder
Bastiodon appears on 0.02% of Regulation M-B teams, which
is 266th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Body Press, on 88.6% of sets.
The item is usually Chople Berry at 47.3%.
The ability is split: Sturdy on 84.4% and Soundproof on 15.6%.
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
Bastiodon is number 411 in the National Dex, a Sinnoh Pokémon, Rock and Steel
with a base stat total of 495 — 137th of the 234 Pokémon
legal in this regulation. Its best stat is Defense at 168, 5th
in the format; its weakest is Speed at 30, 227th.
It can have Sturdy and Soundproof.
The Champions module tiers it UU.
It sits in a 2-stage line: Shieldon → Bastiodon.
Not all of that line is legal in this regulation — Shieldon is not.
What gets through
As Rock and Steel, 3 of the eighteen attacking types do extra damage to it, and Fighting and Ground land for quadruple. It
resists 8 and is immune to 1. The board above
has all of it. One other legal Pokémon shares the same typing and the same board: Aggron.
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 Bastiodon takes extra damage from.
- Garchomp — Earthquake (Ground, ×4), on 85.7% of its sets
- Basculegion — Aqua Jet (Water, ×2), on 96.6% of its sets
- Sneasler — Close Combat (Fighting, ×4), on 99.7% of its sets
- Staraptor-Mega — Close Combat (Fighting, ×4), on 100% of its sets
- Blastoise-Mega — Water Spout (Water, ×2), on 96.4% of its sets
- Swampert-Mega — Wave Crash (Water, ×2), on 97.6% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Bastiodon reaches
90 Speed; left uninvested with a neutral nature it sits at
50. Invested, it outruns 0 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 149.5 kg, so Grass Knot and Low Kick hit it for 100 base
power. That is a real consideration in a format where both are common.
Its move pool
Bastiodon learns 89 moves in the Champions data.
49 of them do damage, across 11 of the eighteen
types, and 13 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Steel Beam at 140 base power, though the biggest number in the pool is Giga Impact at 150.
It has no priority move, so it moves in Speed order every turn.
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.
