What Mega Evolution changes
Charizard, number 6 in the National Dex and a Kanto Pokémon,
holds Charizardite X to become Mega Charizard X,
taking its total from 534 to 634. The biggest single gain is 46 Attack, followed by 33 Defense. Nothing goes down — HP, Sp. Def and Speed stay exactly where they were.
The typing changes: it gains Dragon and drops Flying, which rewrites every matchup below. Mega Evolving replaces Blaze and Solar Power with Tough Claws.
What gets through
As Fire and Dragon, 3 of the eighteen attacking types get through for extra damage. It resists 5. 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 Charizard X is played on 0.79% of teams in the Regulation M-B VGC
ladder, which puts it 78th of the 282 Pokémon with enough games to
measure. The move almost every one of them carries is Protect at 97%.
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 Charizard X takes extra damage from.
- Garchomp — Dragon Claw (Dragon, ×2), on 91.6% of its sets
- Archaludon — Dragon Pulse (Dragon, ×2), on 82.8% of its sets
- Aerodactyl-Mega — Rock Slide (Rock, ×2), on 99.8% of its sets
- Swampert-Mega — Earthquake (Ground, ×2), on 73.4% of its sets
- Venusaur — Earth Power (Ground, ×2), on 77% of its sets
- Mawile-Mega — Rock Slide (Rock, ×2), on 35.4% of its sets
Where it sits among the Megas
Of the 91 Mega forms in the dex, Mega Charizard X is 24th by base
stat total. Its best stat is Attack at 130, which is 45th
among Megas; its worst is HP at 78, 46th.
No other Mega Evolution has the Fire and Dragon typing, so this matchup board is unique to it.
The unevolved Charizard is itself on 0.08% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Charizard X 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
130 points of
Attack actually change a
knockout.
