What it does on the ladder
Umbreon appears on 0.26% of Regulation M-B teams, which
is 131st of the 282 Pokémon with enough games to measure.
The move it almost always carries is Foul Play, on 94.8% of sets.
The item is usually Leftovers at 70.9%.
The ability is split: Inner Focus on 96.1% and Synchronize on 3.9%.
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
Umbreon is number 197 in the National Dex, a Johto Pokémon, Dark
with a base stat total of 525 — 59th of the 234 Pokémon
legal in this regulation. Its best stat is Sp. Def at 130, 9th
in the format; its weakest is Sp. Atk at 60, 173rd.
It can have Synchronize and Inner Focus.
The Champions module tiers it UU.
It sits in a 2-stage line: Eevee → Umbreon.
Not all of that line is legal in this regulation — Eevee is not.
What gets through
As Dark, 3 of the eighteen attacking types do extra damage to it. It
resists 2 and is immune to 1. The board above
has all of it. 3 other legal Pokémon share the same typing and the same board: Liepard, Zoroark, Absol.
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 Umbreon takes extra damage from.
- Whimsicott — Moonblast (Fairy, ×2), on 93.9% of its sets
- Sneasler — Close Combat (Fighting, ×2), on 99.7% of its sets
- Floette-Mega — Dazzling Gleam (Fairy, ×2), on 95.9% of its sets
- Staraptor-Mega — Close Combat (Fighting, ×2), on 100% of its sets
- Grimmsnarl — Spirit Break (Fairy, ×2), on 59.3% of its sets
- Blastoise-Mega — Aura Sphere (Fighting, ×2), on 34.2% of its sets
Speed and weight
At level 50 with a boosting nature and full investment, Umbreon reaches
128 Speed; left uninvested with a neutral nature it sits at
85. Invested, it outruns 5 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 27 kg, so Grass Knot and Low Kick hit it for 60 base
power. That is a real consideration in a format where both are common.
Its move pool
Umbreon learns 103 moves in the Champions data.
46 of them do damage, across 9 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 Foul Play at 95 base power, though the biggest number in the pool is Giga Impact at 150.
It also has priority: Sucker Punch at +1 and 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.
