What Mega Evolution changes
Sharpedo, number 319 in the National Dex and a Hoenn Pokémon,
holds Sharpedonite to become Mega Sharpedo,
taking its total from 460 to 560. The biggest single gain is 30 Defense, followed by 25 Sp. Def. Nothing goes down — HP stays exactly where it was.
The typing does not change — it is Water and Dark before and after — so the Mega is the same defensive problem as the base form, only bigger. Mega Evolving replaces Rough Skin and Speed Boost with Strong Jaw.
What gets through
As Water and Dark, 5 of the eighteen attacking types get through for extra damage. 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 Sharpedo is played on 0.03% of teams in the Regulation M-B VGC
ladder, which puts it 252th of the 282 Pokémon with enough games to
measure. The move almost every one of them carries is Protect at 99.9%.
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 Sharpedo takes extra damage from.
- Charizard-Mega-Y — Solar Beam (Grass, ×2), on 82.2% of its sets
- Sinistcha — Matcha Gotcha (Grass, ×2), on 97.9% of its sets
- Whimsicott — Moonblast (Fairy, ×2), on 93.9% of its sets
- Sneasler — Close Combat (Fighting, ×2), on 99.7% of its sets
- Farigiraf — Thunderbolt (Electric, ×2), on 59.2% of its sets
- Floette-Mega — Dazzling Gleam (Fairy, ×2), on 95.9% of its sets
Where it sits among the Megas
Of the 91 Mega forms in the dex, Mega Sharpedo is 84th by base
stat total. Its best stat is Attack at 140, which is 35th
among Megas; its worst is Sp. Def at 65, 89th.
2 other Megas share the Water and Dark typing and therefore this exact matchup board: Mega Gyarados, Mega Greninja.
The unevolved Sharpedo is itself on 0.03% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Sharpedo 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
140 points of
Attack actually change a
knockout.
