What Mega Evolution changes
Medicham, number 308 in the National Dex and a Hoenn Pokémon,
holds Medichamite to become Mega Medicham,
taking its total from 410 to 510. The biggest single gain is 40 Attack, followed by 20 Sp. Atk. Nothing goes down — HP stays exactly where it was.
The typing does not change — it is Fighting and Psychic before and after — so the Mega is the same defensive problem as the base form, only bigger. The ability stays Pure Power.
What gets through
As Fighting and Psychic, 3 of the eighteen attacking types get through for extra damage. It resists 2. 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 Medicham is played on 0.07% of teams in the Regulation M-B VGC
ladder, which puts it 208th of the 282 Pokémon with enough games to
measure. The move almost every one of them carries is Fake Out at 92.3%.
The Champions module tiers it UUBL.
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 Medicham takes extra damage from.
- Basculegion — Last Respects (Ghost, ×2), on 99.9% of its sets
- Whimsicott — Moonblast (Fairy, ×2), on 93.9% of its sets
- Floette-Mega — Dazzling Gleam (Fairy, ×2), on 95.9% of its sets
- Pelipper — Hurricane (Flying, ×2), on 98.1% of its sets
- Staraptor-Mega — Brave Bird (Flying, ×2), on 83.4% of its sets
- Grimmsnarl — Spirit Break (Fairy, ×2), on 59.3% of its sets
Where it sits among the Megas
Of the 91 Mega forms in the dex, Mega Medicham is 88th by base
stat total. Its best stat is Attack at 100, which is 67th
among Megas; its worst is HP at 60, 87th.
2 other Megas share the Fighting and Psychic typing and therefore this exact matchup board: Mega Gallade, Mega Mewtwo X.
The unevolved Medicham is itself on 0.10% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Medicham 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
100 points of
Attack actually change a
knockout.
