What Mega Evolution changes
Glalie, number 362 in the National Dex and a Hoenn Pokémon,
holds Glalitite to become Mega Glalie,
taking its total from 480 to 580. The biggest single gain is 40 Attack, followed by 40 Sp. Atk. Nothing goes down — HP, Defense and Sp. Def stay exactly where they were.
The typing does not change — it is Ice before and after — so the Mega is the same defensive problem as the base form, only bigger. Mega Evolving replaces Inner Focus, Ice Body and Moody with Refrigerate.
What gets through
As Ice, 4 of the eighteen attacking types get through for extra damage. It resists 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 Glalie is played on 0.03% of teams in the Regulation M-B VGC
ladder, which puts it 248th of the 282 Pokémon with enough games to
measure. The move almost every one of them carries is Protect at 95.2%.
The Champions module tiers it UU.
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 Glalie takes extra damage from.
- Kingambit — Iron Head (Steel, ×2), on 67.8% of its sets
- Incineroar — Flare Blitz (Fire, ×2), on 91.2% of its sets
- Garchomp — Rock Slide (Rock, ×2), on 75.9% of its sets
- Charizard-Mega-Y — Heat Wave (Fire, ×2), on 99.2% of its sets
- Sneasler — Close Combat (Fighting, ×2), on 99.7% of its sets
- Archaludon — Flash Cannon (Steel, ×2), on 94.9% of its sets
Where it sits among the Megas
Of the 91 Mega forms in the dex, Mega Glalie is 75th by base
stat total. Its best stat is Attack at 120, which is 55th
among Megas; its worst is Sp. Def at 80, 83rd.
No other Mega Evolution has the Ice typing, so this matchup board is unique to it.
The unevolved Glalie is itself on 0.01% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Glalie 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
120 points of
Attack actually change a
knockout.
