This guide answers the type-chart part of searches such as “Mega Starmie weakness.” It separates confirmed Pokémon GO event details from Type Matchup's standard type-chart planning. It does not assume a moveset, counter lineup, damage breakpoint, group size, or encounter result.

Official facts vs. Type Matchup planning

Officially confirmed: The Starmie Super Mega Raid Day runs August 22 from 11:00 a.m. to 5:00 p.m. local time. Mega Starmie will debut in Pokémon GO's Super Mega Raids. The announcement also specifies up to six free Raid Passes, increased Rare Candy XL chances, and an increased Remote Raid Pass limit for the event window.

Type Matchup planning: Starmie is Water/Psychic-type in the official Pokédex. The weakness notes below apply the standard type chart to that typing as a planning baseline. Pokémon GO's live moves, battle values, Super Mega Raid mechanics, and your group can change the practical result. The official event announcement does not name best counters, a moveset, damage breakpoints, or a minimum group size.

What is Mega Starmie weak to?

For standard Water/Psychic-type planning, start with these attacking types:

• Electric: super effective against Water.
• Grass: super effective against Water.
• Bug: super effective against Psychic.
• Ghost: super effective against Psychic.
• Dark: super effective against Psychic.
• Fire, Water, Ice, Fighting, Psychic, and Steel: are resisted by the Water/Psychic combination in the standard type chart, so they are not the type advantage to prioritize from a type-only perspective.

Review the full Water type guide and Psychic type guide, then compare possible coverage in the type matchup calculator. You can also check Electric, Grass, Bug, Ghost, and Dark before planning your team.

August 22 Mega Starmie raid checklist

Pokémon GO says the event includes an increased chance of Rare Candy XL from Raid Battles and a Remote Raid Pass limit of 20 from August 21 at 2:00 p.m. through August 22 at 8:00 p.m. PDT. The announced paid ticket has separate benefits, including additional Raid Passes; availability and pricing can vary by region.

For a type-focused plan:

1. Confirm your local event time in Pokémon GO: August 22, 11:00 a.m. to 5:00 p.m.
2. Start with Electric, Grass, Bug, Ghost, or Dark coverage, then check the live moves and Super Mega Raid mechanics.
3. Spin Gym Photo Discs during the event to access the announced allowance of up to six free Raid Passes.
4. Compare the rest of your team in the team weakness calculator, rather than treating a standard-chart advantage as a complete battle plan.
