What Mega Evolution changes
Dragonite, number 149 in the National Dex and a Kanto Pokémon,
holds Dragoninite to become Mega Dragonite,
taking its total from 600 to 700. The biggest single gain is 45 Sp. Atk, followed by 25 Sp. Def. It also loses 10 Attack.
The typing does not change — it is Dragon and Flying before and after — so the Mega is the same defensive problem as the base form, only bigger. The ability stays Multiscale.
What gets through
As Dragon and Flying, 4 of the eighteen attacking types get through for extra damage, and Ice lands for quadruple. It resists 5 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 Dragonite is played on 2.4% of teams in the Regulation M-B VGC
ladder, which puts it 54th of the 282 Pokémon with enough games to
measure. The move almost every one of them carries is Protect at 64.9%.
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 Dragonite takes extra damage from.
- Garchomp — Dragon Claw (Dragon, ×2), on 91.6% 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
- Archaludon — Dragon Pulse (Dragon, ×2), on 82.8% of its sets
- Grimmsnarl — Spirit Break (Fairy, ×2), on 59.3% of its sets
- Aerodactyl-Mega — Rock Slide (Rock, ×2), on 99.8% of its sets
Where it sits among the Megas
Of the 91 Mega forms in the dex, Mega Dragonite is 7th by base
stat total. Its best stat is Sp. Atk at 145, which is 23rd
among Megas; its worst is HP at 91, 19th.
2 other Megas share the Dragon and Flying typing and therefore this exact matchup board: Mega Rayquaza, Mega Salamence.
The unevolved Dragonite is itself on 2.5% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Dragonite 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
145 points of
Special Attack actually change a
knockout.
