What Mega Evolution changes
Charizard, number 6 in the National Dex and a Kanto Pokémon,
holds Charizardite Y to become Mega Charizard Y,
taking its total from 534 to 634. The biggest single gain is 50 Sp. Atk, followed by 30 Sp. Def. Nothing goes down — HP, Defense and Speed stay exactly where they were.
The typing does not change — it is Fire and Flying before and after — so the Mega is the same defensive problem as the base form, only bigger. Mega Evolving replaces Blaze and Solar Power with Drought.
What gets through
As Fire and Flying, 3 of the eighteen attacking types get through for extra damage, and Rock lands for quadruple. It resists 6 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 Charizard Y is played on 26.5% of teams in the Regulation M-B VGC
ladder, which puts it 6th of the 277 Pokémon with enough games to
measure. The move almost every one of them carries is Heat Wave at 99.9%.
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 Y takes extra damage from.
- Garchomp — Rock Slide (Rock, ×4), on 84% of its sets
- Basculegion — Aqua Jet (Water, ×2), on 96.8% of its sets
- Farigiraf — Thunderbolt (Electric, ×2), on 44.8% of its sets
- Raichu-Mega-Y — Zap Cannon (Electric, ×2), on 99.7% of its sets
- Blastoise-Mega — Water Spout (Water, ×2), on 90.6% of its sets
- Archaludon — Electro Shot (Electric, ×2), on 97.9% of its sets
Where it sits among the Megas
Of the 93 Mega forms in the dex, Mega Charizard Y is 22nd by base
stat total. Its best stat is Sp. Atk at 159, which is 17th
among Megas; its worst is Defense at 78, 76th.
No other Mega Evolution has the Fire and Flying typing, so this matchup board is unique to it.
The unevolved Charizard is itself on 0.02% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Charizard Y 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
159 points of
Special Attack actually change a
knockout.
