What it does

The Pokemon at the user's position steals 1/8 of the target's maximum HP, rounded down, at the end of each turn. If Big Root is held by the recipient, the HP recovered is 1.3x normal, rounded half down. If the target uses Baton Pass, the replacement will continue being leeched. If the target switches out or uses Mortal Spin or Rapid Spin successfully, the effect ends. Grass-type Pokemon are immune to this move on use, but not its effect.

Who carrys it

9 of the 282 Pokémon measured on the Regulation M-B ladder carry Leech Seed. The one that matters most is Venusaur, which is on 12.1% of teams and carrys it on 3.7% of its sets. The full list is above, ordered by how much of the format each one is.

What it hits

As a Grass move it is super effective against Ground, Rock and Water, resisted by Bug, Dragon, Fire, Flying, Grass, Poison and Steel. 7 other Grass moves appear in this format: Solar Beam, Sleep Powder, Giga Drain, Leaf Storm, Energy Ball, Grass Knot and others.

Who could and does not

21 Pokémon legal in this regulation can learn Leech Seed at all, against the 9 that actually bring it. The gap is the interesting number: it is the set of Pokémon that have the option and decline it. The most-played of those are Whimsicott, Meowscarada, Serperior, Sceptile, Gourgeist-Large and Leafeon — each of them measured on the ladder, each of them leaving this move on the shelf.

How concentrated it is

Across the ladder, Leech Seed accounts for an expected 0.02 of the six slots on an average team, which makes it the 110th most-brought of the 126 moves this format runs. 22% of that comes from Venusaur alone, so it is spread across the field rather than propped up by one Pokémon. Its carriers are mostly Grass (9), Poison (2) and Ghost (2).

Where these numbers come from

Usage is Smogon's published statistics for the Regulation M-B VGC ladder, and the description is the one shipped in the Pokémon Showdown data set. Both are regenerated on every build rather than written by hand, so this page follows the format instead of trailing it. Take any of it to the team builder or the damage calculator.
