What it does on the ladder
Rotom-Fan appears on 0.01% of Regulation M-B teams, which
is 266th of the 277 Pokémon with enough games to measure.
The move it almost always carries is Volt Switch, on 88.8% of sets.
The item is usually Choice Scarf at 90.6%.
Every one of them runs Levitate.
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
Rotom-Fan is number 479 in the National Dex, a Sinnoh Pokémon, Electric and Flying
with a base stat total of 520 — 82nd of the 234 Pokémon
legal in this regulation. Its best stat is Defense at 107, 42nd
in the format; its weakest is HP at 50, 230th.
Its only ability is Levitate.
The Champions module tiers it UU.
It has no evolutions on either side; what you see is the whole line.
What gets through
As Electric and Flying, 2 of the eighteen attacking types do extra damage to it. It
resists 5 and is immune to 1. The board above
has all of it. One other legal Pokémon shares the same typing and the same board: Emolga.
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 Rotom-Fan takes extra damage from.
- Garchomp — Rock Slide (Rock, ×2), on 84% of its sets
- Froslass-Mega — Blizzard (Ice, ×2), on 99.2% of its sets
- Aerodactyl-Mega — Rock Slide (Rock, ×2), on 99.4% of its sets
- Swampert-Mega — Ice Punch (Ice, ×2), on 82.6% of its sets
- Ninetales-Alola — Blizzard (Ice, ×2), on 98.3% of its sets
- Milotic — Icy Wind (Ice, ×2), on 49.5% of its sets
Against its own formes
Rotom has 6 legal formes in this regulation and they share a
typing, so the only thing separating them is the stat line.
This one has the highest Attack at 65, Defense at 107, Sp. Atk at 105 and Sp. Def at 107 of the 6.
It has the lowest Speed at 86.
The others are Rotom-Wash, Rotom-Heat, Rotom-Mow, Rotom-Frost and Rotom.
Speed and weight
At level 50 with a boosting nature and full investment, Rotom-Fan reaches
151 Speed; left uninvested with a neutral nature it sits at
106. Invested, it outruns 10 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 0.3 kg, so Grass Knot and Low Kick hit it for 20 base
power. That is a real consideration in a format where both are common.
Its move pool
Rotom-Fan learns 43 moves in the Champions data.
20 of them do damage, across 6 of the eighteen
types, and 8 share a type with it and so get the same-type bonus.
Its hardest-hitting same-type move is Thunder at 110 base power.
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.
