What it does on the ladder
Jolteon appears on 0.23% of Regulation M-B teams, which
is 139th of the 282 Pokémon with enough games to measure.
The move it almost always carries is Protect, on 59.3% of sets.
The item is usually Life Orb at 44.8%.
The ability is split: Volt Absorb on 94.2% and Quick Feet on 5.8%.
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
Jolteon is number 135 in the National Dex, a Kanto Pokémon, Electric
with a base stat total of 525 — 60th of the 234 Pokémon
legal in this regulation. Its best stat is Speed at 130, 3rd
in the format; its weakest is Defense at 60, 210th.
It can have Volt Absorb and Quick Feet.
The Champions module tiers it UU.
It sits in a 2-stage line: Eevee → Jolteon.
Not all of that line is legal in this regulation — Eevee is not.
What gets through
As Electric, 1 of the eighteen attacking types do extra damage to it. It
resists 3. The board above
has all of it. 7 other legal Pokémon share the same typing and the same board: Raichu, Bellibolt, Pikachu, Luxray, Manectric and others.
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 Jolteon takes extra damage from.
- Garchomp — Earthquake (Ground, ×2), on 85.7% of its sets
- Swampert-Mega — Earthquake (Ground, ×2), on 73.4% of its sets
- Venusaur — Earth Power (Ground, ×2), on 77% of its sets
- Venusaur-Mega — Earth Power (Ground, ×2), on 95.6% of its sets
- Hydreigon — Earth Power (Ground, ×2), on 58.8% of its sets
- Excadrill — High Horsepower (Ground, ×2), on 56.9% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Jolteon reaches
200 Speed; left uninvested with a neutral nature it sits at
150. Invested, it outruns 18 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 24.5 kg, so Grass Knot and Low Kick hit it for 40 base
power. That is a real consideration in a format where both are common.
Its move pool
Jolteon learns 101 moves in the Champions data.
50 of them do damage, across 11 of the eighteen
types, and 12 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Zap Cannon at 120 base power, though the biggest number in the pool is Giga Impact at 150.
It also has priority: Quick Attack at +1.
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.
