What Mega Evolution changes
Slowbro, number 80 in the National Dex and a Kanto Pokémon,
holds Slowbronite to become Mega Slowbro,
taking its total from 490 to 590. The biggest single gain is 70 Defense, followed by 30 Sp. Atk. Nothing goes down — HP, Attack, Sp. Def and Speed stay exactly where they were.
The typing does not change — it is Water and Psychic before and after — so the Mega is the same defensive problem as the base form, only bigger. Mega Evolving replaces Oblivious, Own Tempo and Regenerator with Shell Armor.
What gets through
As Water and Psychic, 5 of the eighteen attacking types get through for extra damage. It resists 6. 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 Slowbro is played on 0.15% of teams in the Regulation M-B VGC
ladder, which puts it 163th of the 277 Pokémon with enough games to
measure. The move almost every one of them carries is Slack Off at 54.4%.
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 Slowbro takes extra damage from.
- Kingambit — Sucker Punch (Dark, ×2), on 99.9% of its sets
- Incineroar — Throat Chop (Dark, ×2), on 51.4% of its sets
- Basculegion — Last Respects (Ghost, ×2), on 99.9% of its sets
- Charizard-Mega-Y — Solar Beam (Grass, ×2), on 64.4% of its sets
- Sinistcha — Matcha Gotcha (Grass, ×2), on 97.8% of its sets
- Farigiraf — Thunderbolt (Electric, ×2), on 44.8% of its sets
Where it sits among the Megas
Of the 93 Mega forms in the dex, Mega Slowbro is 62nd by base
stat total. Its best stat is Defense at 180, which is 3rd
among Megas; its worst is Speed at 30, 91st.
One other Mega shares the Water and Psychic typing and therefore this exact matchup board: Mega Starmie.
The unevolved Slowbro is itself on 0.05% of teams.
Putting it on a team
A Mega slot is a commitment: the stone occupies the held item, so whatever Mega Slowbro 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
Special Attack actually change a
knockout.
