What Mega Evolution changes
Swampert, number 260 in the National Dex and a Hoenn Pokémon,
holds Swampertite to become Mega Swampert,
taking its total from 535 to 635. The biggest single gain is 40 Attack, followed by 20 Defense. Nothing goes down — HP stays exactly where it was.
The typing does not change — it is Water and Ground before and after — so the Mega is the same defensive problem as the base form, only bigger. Mega Evolving replaces Torrent and Damp with Swift Swim.
What gets through
As Water and Ground, 1 of the eighteen attacking types get through for extra damage, and Grass lands for quadruple. It resists 4 and is outright immune to 1. The full board is above; the short version is that the
types listed under ×2 and ×4 are the ones worth planning around.
On the Regulation M-B ladder
Mega Swampert is played on 7.2% of teams in the Regulation M-B VGC
ladder, which puts it 22th of the 277 Pokémon with enough games to
measure. The move almost every one of them carries is Protect at 99%.
The Champions module tiers it OU.
Those figures come from Smogon's published usage statistics rather than from anything measured
here, and they describe what the ladder plays, not what is strongest.
What threatens it
Smogon publishes no head-to-head checks-and-counters data for doubles formats, so this list is
computed, not measured: these are the most-played Regulation M-B Pokémon carrying
a damaging move of a type Mega Swampert takes extra damage from.
- Charizard-Mega-Y — Solar Beam (Grass, ×4), on 64.4% of its sets
- Sinistcha — Matcha Gotcha (Grass, ×4), on 97.8% of its sets
- Venusaur — Leaf Storm (Grass, ×4), on 59.2% of its sets
- Scovillain-Mega — Giga Drain (Grass, ×4), on 67% of its sets
- Venusaur-Mega — Giga Drain (Grass, ×4), on 82.9% of its sets
- Meowscarada — Flower Trick (Grass, ×4), on 99.2% of its sets
Where it sits among the Megas
Of the 93 Mega forms in the dex, Mega Swampert is 21st by base
stat total. Its best stat is Attack at 150, which is 19th
among Megas; its worst is Speed at 70, 72nd.
No other Mega Evolution has the Water and Ground typing, so this matchup board is unique to it.
The unevolved Swampert is itself on 1.2% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Swampert would have
wanted from an item, it does not get. Drop it into the
team builder to see what the rest of the six then have to cover,
or take it to the damage calculator to find out whether those
150 points of
Attack actually change a
knockout.
